Audio recording laws in the United States

With so much great technology on the market these days, it is easier to record conversations than ever before – either over a land line, on a mobile phone or even in-person with a hidden recording device. Recorded conversations (either tape or digital) are often very helpful in a variety of scenarios. These audio recordings may assist in an investigation of employee misconduct or in business or personal lawsuits, even in potential criminal investigations.
It is very important, however, to make sure that any recording, either of a phone conversation or an in-person conversation, complies with federal and state laws.  Otherwise, you may very well open yourself up to criminal charges or civil suits.  And it is unlikely that you will be legally able to use the recording for your original purpose.
So, if you’re thinking about recording some phone calls or placing a voice-activated recorder in a room to record conversations, you’ll need to take a look at the applicable laws.  The first place to look is at the federal wiretapping statute – also known as the Electronic Communications Privacy Act.  Federal law allows phone calls (traditional, cellular and cordless) and other electronic communication to be recorded with the consent of at least one party to the conversation.
This means that if you are one of the people taking part in the conversation, it can be recorded (because one person – you – has consented to the recording).  If you are not taking part in the conversation, at least one of the people in the conversation must know about and consent to the recording.
You can’t stop, however, after considering federal law and assume that your recording passes muster.  Each state and territory has its own statutes regarding the recording of conversations.  Most state wiretapping and eavesdropping laws are based upon the federal law and allow recording with the consent of one party to the conversation.
The 37 states which allow “one party consent” recording of oral communications are: Alaska, Arkansas, Colorado, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, West Virginia, Wisconsin and Wyoming.  The District of Columbia also allows people to record conversations with the consent of only one party.  Nevada has a one party consent statute but there is some question as to how the law should be interpreted by the courts – it could be considered an “all party consent” state.
The 12 states which definitely require all parties to a conversation to consent before it can be recorded are: California, Connecticut, Delaware, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania and Washington.  (In California, there is an exception – you can record a conversation with the consent of only one party if certain criminal activity (kidnapping, extortion, bribery or a violent felony) is involved.)

So, the basic rule is that it is illegal to record conversations or communications in which you are not a participant, unless you have consent of at least one, if not all, of the participants.  The obvious exception to this general rule is that law enforcement officials can seek permission from a court to perform no-consent wiretaps as part of a criminal investigation.  For the finer points of your own state’s laws and requirements, you should always consult with an attorney.

How to detect if there is a hidden voice recorder

If you suspect that someone is spying on you, you might want to know how to detect spy devices. There are tools you can use, which are essentially high-frequency scanners, that will tell you when someone is watching you or listening in on your conversations. These tools can be used to detect cameras, cell phones or microphones.

1. Choose your radio frequency (RF) scanner. There are a number of scanners available that will detect both audio and video transmissions of both wired and wireless devices. These devices come in various sizes and strengths. Some of them will fit on a key chain while the more professional ones will fit in the palm of your hand. As of 2009, these devices range in price from $50 to $700, depending on your needs.  

2.Scan your office or home using a spy detection device. These are very easy to use. You simply wave it around the area that you wish to scan and when it detects a signal-transmitting device on a high frequency, such as those emitted by a cellular phone or peeping camera, an LED will light up and there will be a beeping sound that will become more rapid as the signal gets stronger.

3.Adjust the device to your preference. Some scanners can detect both digital and analog signals and will detect signals from 1-6 GHZ, which is typically the frequency people use to communicate. Some scanners can be set to vibrate mode so that you do not alert those who are listening that they are being scanned. This way you can provide misinformation if you want.

Reasons why I need a GPS Tracker

It's always been difficult to know when to invest in a new piece of technology. Undoubtedly, in years long past, farmers fretted over whether they could afford a McCormick reaper, or whether it really was time to buy a car and see what the livery's giving for a used horse.
Of course, this has only accelerated in recent years. These days, you can't go six months without someone telling you about some new future technology that's suddenly here after all. This is great if you like high tech, but the market reality is that this rapid innovation also leaves many husks of failed products in its wake.
So, if your transportation  is looking for new ways to save money on your fleet, it's understandable if you were reticent to add more gadgets to them as a solution. However, fleet tracking is a technology that is here to stay.
GSM GPS Tracker Technologies Are Stable
GSM GPS Tracker Systems combine two long-established technologies into a single solution that gives you unparalleled oversight of your fleet. At heart, all they do is take the GPS satellite navigation data for your vehicle, and relay it to you through the standard GSM cell phone network. The tracker itself is long-lived, unobtrusive, and inexpensive, and everything else is handled by the mapping software back in the office.
As far as longevity goes, this is nearly as rock-solid as it gets. The GPS system required putting satellites into orbit, and is used in nearly every country on Earth. It's not going anywhere. Similarly, the GSM bands aren't leaving any time soon, given how ubiquitous cell phone use has become. Even if the voice market shifted to something with more bandwidth, GSM would continue to be perfect for industrial applications.
In short, this is a technology your vehicles should be able to rely on for years, if not decades, to come.
Five Solid Reasons To Invest In GSM GPS Tracker Systems
These fleet tracking technologies can solve a number of different issues within a fleet operation. Here are a few of the scenarios where GSM GPS trackers make sense:

1. Maintenance issues with your vehicles tend to rear their head unexpectedly, making for costly additions to your budget. A GPS tracker includes sensors for a number of vehicle functions, allowing the system to track the performance of each vehicle over time. Subtle clues such as an increase in fuel use can tip you off before a small problem becomes a big one.
   
2. If you're having trouble with getting complete data sets to submit, whether for reimbursement or government bureaucracy, GPS vehicle fleet tracking gives you all the data you need. Besides having precise numbers, it enables the creation of detailed reports covering numerous aspects of your vehicles.
   
3. Those simply looking to save money can also harness the data being tracked. You'll get a detailed view of your fuel and maintenance costs. By examining them, you'll be able to put together more detailed recommendations for driver procedures, based on hard data gathered in the field.
   
4. Performance reviews also become far easier, as you'll now truly know what your drivers are doing in the field. Those who regularly break speed limits or internal policies can be flagged, and those with exemplary driving can be praised or rewarded for it. It takes the guess work out of performance reviews by giving you and your drivers the data you need to improve.
   
5. Cargo can also be tracked.  Add on RFID readers and you can track exactly where and when your cargo was loaded and unloaded.
   

Adding GSM GPS tracker systems to your fleet is an idea that has certainly come into its time. It's a solid piece of technology that will continue to be in use well into the foreseeable future, based on technologies that already have decades behind them.

How Do I Know If My Cell Phone Has Been Bugged

How do you find out if your cell phone is tapped? Well, someone who is wondering why the battery life on that newly purchased cell phone is shorter than expected or suspecting that weird sound the phone makes has something to do with privacy meaning their cell phone being tapped, they have hit the nail on the head!
Unless that person is involved in a crime, breach of trust, unpleasant activities or feeling some discomfort, there is nothing to worry about but to stay cool and get going.
Of course, no one really wants their cell phone to be tapped so here is some more information on how you can tell if your cell phone is tapped and what exactly you can do about it.

What to Look for When Suspicious

Although it is illegal to tap someone’s cell phone without their consent, the advent of high-tech has shown those culprits who are looking into intruding personal space of an unsuspecting victim in order to steal that critical information or call records, various sophisticated ways to do it without leaving a trace. Following is a list of signs to look for, that might indicate that the cell phone security has been compromised:

• The cell phone battery feels warmer than usual room temperature when not in use
• The cell phone goes on or off without operating it, unless the battery is too low
• Static noise heard with regular intervals, clicking or other background sounds
• The cell phone needs frequent charging which is unusual when the device is new
• The switch off time long enough to make someone frustrated is another sign, unless the phone is experiencing hardware glitches
• Screen distortion
• Strange numbers on the display or monthly statement

Victims of Cell Phone Tapping

The chances are high that a well-mannered person’s cell phone is clean and free from malicious stuffs but one need to be highly vigilant when it comes to protecting privacy as there are many reasons to believe why it was invaded in the first place. Some of the potential suspects to make note of are:

• Spouse of dubious nature
• A nosy boss
• A random prankster
• Marketing spammers
• Investigating departments

It is most likely that the person whose cell phone gets tapped is either unaware of any signs of phone tapping or just leading a busy life.

Techniques to Tap a Cell Phone

A broad knowledge in the abuse of hi-tech gadgets is as important to one as the fancy usage of them. Taking that into mind, though it is not recommended, calls and other details from a cell phone can be tapped using various techniques as explained below:

1. The Multi-track system, an external device manufactured and distributed by some surveillance product companies or Spy data extractor similar to USB drive can be used to read the data from the Cell Phone into the computer which then reveals all the messages and numbers that has been deleted from the phone and in some cases, recorded conversations.
2. Another option is to purchase a call recorder card that can be filled in with minutes during purchase and the phone number to be tapped is entered according to the instructions given, while all the calls that are received by the phone being tapped are forwarded to a switch provided by the company which are retrieved later.
3. Certain softwares like FlexiSpy and RecordiaPro installed into the cell phone, makes the conversation available in real time or records it for later usage by accessing the relevant system. Other software that are coupled with GPS features make it possible for someone to track down the exact location of the device at a fingertip.
4. Online surveillance providers let the user track the phone by entering the number in their website thus pin-pointing the geographic position of the device.

How to Protect a Cell Phone from Being Tapped

Just like every problem has a solution and every virus has an anti-virus, a tapped cell phone has an easy way out of all the mess if one knows how to dot all the i’s and cross all the t’s. Here are a few:

• Reporting the intrusion to anti-crime squads or private investigating agencies will save a lot of time and energy spent in figuring out the possibility.
• Taking a chance by asking the suspect directly is another way to get through it.
• Service providers normally are equipped with all the required technology to find out the breach and provide them to customers upon request. The providers can then completely wipe out the bugs and restore the device manufacturer settings.
• Having a password enabled lock system or taking the battery out when not in use is recommended too.
• Phones and devices that are less sophisticated and less experimented with are a better option if one is really concerned about the security issues because the software for such devices are either outdated or hard to find making it hard for the intruder to break through it precisely.
• Leaving the cell phone around to bask in the sun or warm-up at the gym or listen to the rest of the speech will make it easier for the culprit to get a hand on it. Hence it is always good to be on the safe side than to repent later.

Last but not least, only authorized Government agents are allowed to tap a cell phone. For the rest of the population doing such a thing is highly illegal which in fact could land them in jail.
Many cell phone tapping crimes happening each and every day some of which go unnoticed and untraced, adversely affect the life of both personal users and large scale businesses. While most monetary losses can be compensated with proper backup or insurance, the ones that are irreplaceable, like trust, are lost forever.

How A GPS Tracker Works

GPS tracking devices can be used to track people, vehicles and other assets, anywhere on Earth. Currently, there are 27 satellites orbiting the earth, 24 are operational, the other three will become operational if one of the satellites happen to fail. At any given time there are at least three satellites that are visible in the sky from a location. These satellites then triangulate on the position of the GPS tracking device. By continuing to triangulate the coordinates at regular intervals, the satellites can determine the speed of an object, the distance traveled and how long it has been stationary.
There are two main types of GPS tracking systems currently on the market today. They are classified as Passive and Active/Live (real-time) Tracking.
KJB Security's passive GPS tracking devices include the I Trail historical tracker.
US Fleet Tracking's active GPS tracking systems include the PT-X5 real-time GPS tracker and the OBD-X5 tracker.
Not all GPS tracking devices are created equal. When considering the purchase of a GPS tracking unit, comparisons should be made based on accuracy, sensitivity, frequency of sampling points, power sources, reliability, and the software that translates the data into an understandable, easy-to-use format.

GPS Tracking Accuracy

All Us Fleet Tracking GPS tracking devices, whether they are active or passive, provide locations that are accurate within 2.5 meters (or roughly 7 feet).

GPS Tracking Sensitivity

Since GPS Tracking for many users is covert in nature, the tracking device needs to be manufactured in a way that maximizes GPS reception. Most traditional GPS devices need a clear view of the sky and will lose GPS reception if placed in some concealed positions. The Us Fleet Tracking line of GPS tracking devices have been designed with that concern in mind. They are sensitive enough that they can be hidden in covert locations while retaining and maintaing good reception.

GPS Tracking Frequency of Sampling Points

The KJB Security passive I Trail GPS Tracking device capture and store GPS signals including time, position, and speed once every second. Competing products capture data once every five (5) to ten (10) seconds per sampling. The second-by-second data represents a better flow of information that can be used to generate greater and more detailed reports.

GPS Tracking Power Sources

Since the majority of GPS tracking customers prefer portability from their units, it is critical for the devices to be able to manage power efficiently. All of Us Fleet Tracking's devices provide a minimum of 20 hours of wheels in motion tracking. Internal sensors put the device into sleep mode when the vehicle is not in motion, which helps in extending battery life. Users of the device can expect to receive days or even weeks of tracking ability. Results will vary based on the number of hours in motion per day.

GPS Tracking Reliability

All Us Fleet Tracking products go through extensive pre-development research and testing to ensure that our customers are purchasing products that are at the forefront of GPS tracking technology. These strict requirements have helped in establishing Us Fleet Tracking as an industry leader, making our GPS tracking solutions the systems of choice, regardless of customer type.

GPS Tracking Software

Us Fleet Tracking's vehicle tracking software offers three ways to view and evaluate tracking data in a user-friendly package that will appeal to both novices and advanced computer users.

• Digital street map: Gives a historical, moment-by-moment replay. Shows when and where the vehicle traveled. Screen shows animated tools, including speedometer, clock with second hand and compass.
• Google Earth satellite map: Accurately displays the driving path and stops on a satellite image.
• Text activity report: Gives a daily summary, divides driving activity into segments with detailed descriptions including starting address, departure time, time en route, arrival time, miles traveled and how long the vehicle stayed at each location.

The significance of second by second data is critical in providing a comprehensive, fluid replay of any and all historical tracking data. Any device providing less than second by second recording falls short of these expectations. As an example, Kjb Security Product's Passive GPS Tracking devices are able to record 3,600 positions per driving hour whereas competing devices recording every 5 seconds, which only provides 720 positions per driving hour.

How to find a good Private Investigator

A good private investigator is essential for a number of jobs, and there are several qualities that a professional should have.

Need For A Good Private Investigator

Private detectives are often used by lawyers, and they can research material that is used in a criminal defense case. Police departments have teams of detectives, but a defense lawyer needs a way to research a case on their own.
Detectives are also useful in a divorce and come in handy in a number of specialized situations. Finding an exceptional detective is made easy when shoppers rely on some of the following attributes that should be found in a good private investigator.

Powers of Observation and Concentration

Detectives often have to follow people and need to pay attention to their activities. For this reason, it is essential to find a professional who is astute and catches on very quickly.
This trait is essential and will help investigators find out more about the person or subject that they are investigating. Investigators often have to look past the obvious in order to find the missing link. This is essential when it comes to finding reclusive people.

Communication and Listening Skills

Investigators need to be able to listen closely to their clients, and they must communicate their findings. Searching for a detective that has these attributes will make it easy to retain the right professional.
There are plenty of times when these skills come in handy. Most detectives get paid a good hourly rate, and communication that is short and effective is the key to finding a great investigator at an economical price.

Ability to Keep Secrets

Lots of detectives work in secretive areas, and they may find out a number of disturbing or illegal things about the people who they watch. Privacy is crucial for most people, and clients should be sure that their detective has the discretion to keep everything to themselves.
Most detectives usually operate according to the code of silence, but it is imperative to make sure of this. Communicating this issue from the onset will assist in the selection process.
Imagine if your detective tells your wife you paid him to follow her. This could lead to a disaster, and this is why it is imperative to find a detective who can keep a secret.

Master of Technology

There are plenty of innovations in technology that can be used by investigators to make their jobs more efficient.
Finding a detective that has and knows how to use GPS systems is essential. Chips can now be left on cars, and they will transmit detailed reports as to the vehicle’s whereabouts. This makes it easy to follow anyone and see where they go.
Technology can also be used to perform skip tracing and find missing people. This is the same type of software that is used by professional collection agents. It can provide names and addresses and often tracks people down through third parties. This is the most economical way to find anyone who has dropped off the grid.
Surveillance cameras are another essential component of the job. The latest recording devices can do audio and video, and they are easy to hide in any location. Their data can be downloaded to a computer, and the entire system is incredibly sneaky. This is a great way to track anyone through their entire days.

Organization and Analytical Skills

Often, investigators use their analytical powers to help them break open hard to crack cases.
For instance, cheating spouses usually work hard to disguise their activities. They may buy another cell phone, and they keep their private conversations to this line. They sneak around and meet in out of the way places, and they work hard not to be seen.
Detectives need to be able to see through the smoke and mirrors and track people using their intuition.

Finding an Exceptionally Good Private Investigator
There are many detectives that have some or a combination of these traits. They are often effective at many jobs, but there are times when a person really needs the best.
Detectives should be able to integrate all of the above qualities, and it is ideal when they have a good team to work with. This makes it easy for them to track multiple people at the same time and finish any job quickly.
Divorces, legal proceedings and other issues often cause people to need to learn more about a person. Trusting a good private investigator is the best way for anyone to track someone down or find out some secrets.
Most people have secrets, but a good private investigator can find them out. There are several qualities that the consummate professional should have, and intelligence and analytical ability are two traits that come in handy.

How a Bug Detector Works

Bug detectors are RF (radio frequency) finders. Bug detectors will respond to any wireless device within its range.  This make searching for a bug difficult but not impossible.

Lets first look at what ranges a Bug detector will cover. Many detectors cover from 50MHz - 6.0GHz. This covers the normal frequencies that wireless devices use.
50 MHZ (megahertz) is the low end of the scale this is where you will find most voice transmitters. As you move up the scale to the GHZ (gigahertz) you get into the wireless camera frequencies.
MHz and GHz are just frequency denominators IE: 1000 MHZ is equal to 1 GHZ so a 2.4 GIG camera can also be considered to be a 2400 MHZ and a 5.8 GHZ can be a 5800 MHZ.
This is not to be confused with say a 10 meter radio that runs around 29.0 (lower than the range) or 27.0 (cb radio).

Between 50 and 6000 MHz are where most spy devices are located. The federal government uses between 406- 420 MHZ ( approx).

The process for locating bugs is simple but time consuming. You need to be aware of all the wireless devices you possess. This can include but is not limited to,
Baby monitors 900 - 1200 MHZ (many others)
Wireless Routers 802.11 -(close to 2.4 GHZ)
Cordless phones 5.8-6 GHZ
Some Cell Phones (approx) 900MHz
Wireless Keyboards and Mice
Wireless speakers
There are many other wireless devices that can set off a bug detector so everything that you know to be wireless needs to be turned off, so you can avoid false signals. Other things to keep in mind are that your neighbours may have wireless devices such as routers and cordless phones.

So to start the process turn off everything that you know is wireless. The simple conclusion here is that what ever else you find is a bug or a wireless camera but that is not always true. You need to take interference into account. There is RF everywhere and our bug detectors are sensitive enough to pick it up. RF is generated by microwaves TVs high power lines ans so on.  Di you ever walk under a high power line , like the big towers that run through the US. The feeling you get is RF so much rf that you can feel it. An experiment we used to do is hold a florescet bulb under the power line and it will light up. The RF activates the gas in the tube causing light.

How do you know if you find a bug? Well if you cant use the sensitivity setting on a detector to tune out the alarm . Then you start looking for devices. Bug detectors will not just light up and point to the bug, it is a process. If you get a reading from a solid wall go to the other side of that wall and make sure that ther are no other wireless devices in the area r that the house or apartment next door does not have a wireless router.

Remember that who ever put the bug is had to have access for a certain amount of time, you must take into account wether they had time to open a wall and then repair it so well that you cant tell. Look for more obvious places like in or around cluttered areas or under furniture. that is a much more likely location.

In most cases, children do conduct parties whenever their parents are not home. In that case, you can find out what your son or daughter does when

What is 960H Resolution

960H is the new analog technology allow cameras and DVRs to capture up to 700TVL, the highest TVL available to date. 960H represents the number of horizontal pixels in the CCD image sensor. 960H is the highest resolution available for analog CCTV and provides a 30% increase in resolution in comparison to D1. The greater the resolution, the higher the definition of the video image. 960H enables the CCTV camera to obtain high resolutions of up to 700 TVL. A 960H DVR must complement the 960H camera to realize the high resolution video.
With previous D1 DVRs, although you may have a 650TVL analog camera, you can only record at D1 resolution which can clearly discern only up to 540TVL. With the new 960H DVR, not only can it capture high-resolution 700TVL cameras, but it can also enhance the recording quality of the existing cameras as its full resolution of up to 700TVL will be realized.
Some of the key points of 960H

• an increase in the number of pixels of nearly 30% resulting in significantly enhanced picture detail
• 700TVL highest resolution currently available in Analog
• Backward compatible with D1 cameras and DVRs
• Easily replaces existing analog installations
• Cost increase is minimal (5% to 10%)

What is the average cost of installing a CCTV system in your home

Closed Circuit Television or CCTV has been commonplace in pubs, car parks and shops for many years. Now, however, due mainly to the reduced purchase and installation price, they are becoming more popular with householders who wish to increase the security of their home. If you are thinking of installing CCTV in your home there are a few considerations to be made to ensure you end up with the best system for your needs.

Factors to consider

Before choosing a CCTV system you need to consider what you want it for. CCTV systems are available for four types of function; Monitoring, detecting, recognition and identification. In a monitoring image you will be able to see a wide area on the screen. You will be able to see people and cars moving about, but will not be able to tell what they are doing or who they are. In a detection image you will be able to see any major actions carried out by the person on the screen, such as a fight breaking out or a brick being thrown, but not smaller actions such as the lock on a car door being forced. You will not be able to identify the person in the image, or even whether they are male or female. A recognition image allows you to see more detail. If the person is known to you, you will probably be able to tell who it is, but if it is a stranger you won't be able to make out detailed facial features. You will, however, be able to clearly see what they are doing, so this option is a popular choice for homeowners wanting to see what people approaching their property are doing. Finally, the identification level image shows clear detail of the persons face. This is a good system to use, for example, on a door intercom where you want to record who is entering and leaving a building. This is the only level of CCTV image which is widely accepted in a court of law as evidence of a person's identity. The locations of the CCTV units are also an important consideration. The camera cannot be located on another person's property, for instance a tree or a lamppost, without the written consent of the responsible person or authority. You also need to check if the cameras are included on your home insurance or if they need to be named items, as they are targets for vandalism. You may want to look into liability insurance in case a camera falls and injures a third party. The siting of cameras should allow them to only observe activity on your own property. Viewing public space or other people's property is an infringement of privacy laws and could lead to prosecution. It is advisable to discuss your plans to install CCTV with your neighbours to diffuse any concerns they may have at the outset. You will need to think about what you want the CCTV to do. Systems are available which are motion sensitive and only record when something is moving in their field of vision. Others have built in infra red lighting so they can operate in the dark. Cameras required to monitor wide areas, such as a garden, work better with a fish eye lens, which produces a panoramic view of the area.

The siting of cameras should allow them to only observe activity on your own property. A recognition image allows you to see more detail. It is advisable to discuss your plans to install CCTV with your neighbours to diffuse any concerns they may have at the outset.

Costs to consider

The initial outlay for installing CCTV will entirely depend on the specifications you require, as well as whether you are installing it yourself or using a professional installer to do the job. As well as the initial outlay there are ongoing costs to consider. To keep a CCTV system working well they need to be serviced regularly. For many systems this will just be a clean of the camera lenses and a check of wiring etc. but VCR systems will also require a head clean to function effectively long term. Around 7 days worth of images should be stored at any one time, so 7 days worth of storage needs to be available, either in the form of data storage or VCR tapes. VCR tapes can only be recorded over around 12 times before they lose quality, so if you are choosing a VCR system you will need to factor in this ongoing cost as well. Finally, the CCTV monitoring equipment should be kept in a secure place, as having a theft take place that includes the CCTV equipment would defeat the object of the system, so the purchase of a secure cupboard also needs to be factored in to overall cost.

Around 7 days worth of images should be stored at any one time.

What is the cost of a Home Security Camera System

A home security camera system lets you see who's at the front door before opening it, watch a "blind" spot on the side of your house, keep an eye on your vacation home from a distance or tape a child-care provider . In the past these systems were most often designed and installed by professionals, but changes in low-cost technology provide many more low-cost do-it-yourself options. A modern closed circuit television (CCTV) system usually includes multiple cameras, a DVR (digital video recorder), cables and a monitor.
Typical costs:

• A stand-alone Internet security camera that sends images to your web browser starts around $30-$50, but expect to pay $75-$250 for a useable basic camera, and it can be $300-$1,000 and up for a high-resolution, durable-construction model. Prices increase depending on the image quality, and features such as color, audio, pan/tilt and e-mail alerts. These cameras work independently from a computer, allowing you to watch real-time images via cell phone or the Internet. Cameras in the low- and medium-price ranges deliver fairly low-quality images and often run on batteries.
• An install-it-yourself closed-circuit television (CCTV) preassembled kit with four cameras starts around $200-$400; averages $500-$1,000 depending on the quality of the components and features such as night vision, remote monitoring; and high-end kits can cost $1,000-$1,800 or more with extras such as extra large hard-drive storage capacity. You might require additional cable or other materials to adapt a kit to your specific circumstances.
• Instead of a preassembled kit, some people prefer to buy all the components separately so they can get exactly the system they need (number of cameras, cable lengths, etc.) Cameras are available for around $50-$250 each, depending on type and size; concealed cameras (in smoke detectors, clocks, signs, etc.) can be $200-$400; DVRs run $250-$1,000 or more; and monitor screens start around $100-$500 but can be $500-$4,500 ; and cables average about $15-$50 each, depending on length. A Popular Mechanics writer^[1] tried out a $300 starter kit with one camera, adding five additional cameras at $230-$250 each for a total cost around $1,500, then spent $4,000 on a do-it-yourself installation with multiple high-end cameras and extensive hard-drive storage capacity.
• Hiring a security company to design and install a complete CCTV camera system (including the cost of the equipment) starts around $1,000-$2,000 for a small, basic system (1-4 low-end cameras) but a professionally installed system can easily run $2,000-$9,000 or more. One advantage of hiring professional installers is that they will help you fine-tune what can be a complex system until it meets your needs. What should be included:
• Your choice of systems will depend on the quality of images you need and how much you're willing to spend. A stand-alone Internet camera is the least expensive option, but usually has the lowest quality images and a shorter battery lifespan. Whether they're do-it-yourself or professionally installed, most CCTV system cameras have either a combined video/power cord or, if they're wireless, just a power cord. CCTV systems generally have better images than low-cost Internet cameras, and let you watch several images on a monitor, then select the one you want to enlarge and view as needed.
• Some systems are triggered by motion detectors, so you only watch or record when there's action. Spyshopsusa.com describes the various types of CCTV cameras.
• If you're installing your own system, draw a diagram of your home's layout to determine where you want cameras and how many, required cable lengths, obstacles that might block wireless signals, and other variables. If you hire a company to design and install a camera system, they will tour your home with you to determine exactly what's needed.
• Once the number and position of cameras and other equipment is decided, installation usually involves screwing in mounting brackets, running wires, drilling holes through walls or floors and connecting the equipment.

What are the benefits of Dummy/Imitation Cameras

Homeowners increasingly recognize the need for effective security in and around their property and this includes for many a surveillance system or the appearance of one for the deterrent element it affords. Equally, when businesses struggle in a difficult economy, more and more owners turn to a CCTV camera system or the use of a dummy CCTV camera set up as a tool to help keep honest people honest, and keep dishonest people away from their premises. Full property surveillance can be cost prohibitive and in the case of business may also require extra staff to monitor the system. With a dummy CCTV camera, homeowners and business owners alike can give potential pilferers the impression that some or all of the home or business is covered by 24/7 video security.
Pros of Dummy Security Cameras
Dummy CCTV cameras provide a way for those who are not technically savvy, or those that are on a very limited budget to put a veil of security in place for their home or business. These cameras are virtually indistinguishable from real security camera system devices. Units are shaped like a real camera, come in various designs, even come with the blinking lights people associate with security cameras, although the reality is that a camera with a blinking light is more likely a CCTV dummy camera than it is a real CCTV camera.
More important than the lights and the shapes are the mock cabling that clearly define the dummy CCTV security camera as one with the potential to provide video feed to a security system. Despite the growing availability of wireless CCTV kits, the presence of cabling lends more credibility than a simple camera that does not appear to be attached to a recording device.

Other advantages exist beyond the cost of the actual cameras. Installation is much easier on a dummy CCTV camera, requiring less time or involvement of a professional installer. There is no cabling to pull and connect, just the short cables required to make the camera look like a real security camera. These cameras tend to modify behavior best when used in conjunction with signage and stickers warning people that they are under surveillance.
A commonly accepted positive influence of incorporating fake CCTV cameras into a real security camera system is that it extends coverage. The most value you realize from dummy cameras is the keeping honest people honest effect. A true criminal will attempt to outwit a security system, regardless of its expense or comprehensiveness of coverage.

Mock warnings and dummy cameras keep people who would normally be honest but are tempted for some reason to follow their natural tendencies instead of the pressure to get something for nothing or misbehave in some manner. Thinking that they are under surveillance can push people to do the right thing and not engage in illegal activities.
Possible downsides of a Dummy CCTV Camera
The fact of the matter is that installing dummy security camera is really so much decoration. Because it is not recording, it provides neither increased visibility of what is going on around your premises nor does it provide material for the police or an investigator to use in the course of apprehending real criminals.
The largest risk comes if the “fake” nature of your security cameras becomes known. Some thieves are well educated in the true design and installation of real security systems. These masters of the break-in recognize quickly when a home or business is not making use of or monitoring a real camera system. By testing security system responses, he or she may quickly come to the conclusion your cameras are fake. If it is discovered, you may find that thieves and other criminals talk to one another and your business or home could suffer from a terrible run of theft and vandalism if those are problems in your area. Sadly of course, a fake CCTV camera will naturally not provide the evidence needed for prosecution either.
Any camera system, real or dummy, is most effective against property crime. If the crimes in your area tend to be either violent or alcohol related, no camera will impact the likelihood of these crimes. This is because violent or drunk people generally do not care about consequences or consider the implications of their crime being caught on tape. It is only the rational criminal that worries about this type of security coverage.
In the end, a real and dummy CCTV kit will have similar preventative effects for certain types of crime. If you have concerns about protecting your home from burglars, or crime in a public place, such as inside a store or in the parking lot of a business, these dummy cameras may be an inexpensive way to gain the benefits enjoyed by more comprehensive security systems. Properly deployed, installed and with attention called to them by appropriate signage, these are just one tool in reducing the cost of shrink and increasing the overall site security of your home or business.

How long can your home or business DVR record for

It's not easy to choose the suitable DVR for your home surveillance or business.
How long my DVR will record and store video ? This is a very common question when people try to choose the DVR.
The times of record and store of DVR depends on following factors:
1. Record Mode
2. Record Image Quality
3. The record size.
4. The size of Hard drive
5. Frame Rate
1. Most of DVR can support 24 hours and Motion detection, Alarm detection record methods.
When use different method for record, the strogage time will be different. 24 hours means the DVR record in every second, never stop, It will requre the biggest storeage space (due to the video files is continuelly filling harddirve space).
Motion detection recording means only record when video camera detect movement, then it will start to record, no motion, then no record. Motion detection & Alarm detection method can save more space that means with more record time.
2. Record image quality means the video file size, low quality image will occupy less space, and extend more record time. High resolution quality images means big file size, it will occupy more storage space and with less record time.
3. When record video, DVR can select the record size (or image size), record size changes the amount of data place in the harddrive.
Commonly DVR record video at CIF (352 * 288), now some DVR can support record size of D1(704*480). The big size of image, the less time DVR can record.
4. For Harddrive, the bigger storage size of the drive, the longer of record time. Typically for harddrive, it should start from 500 GB and it can reach to 2 TB. Most of DVRs can connect to 2 pcs of 2TB SATA harddrive.
Some big size DVR can put into 4 pcs of harddrive (like 97 series DVR).
5. Frame Rate, movie records and plays at 24 fps (pictures/frames per second). Real time recording for DVR systems is 30 fps. Most of time 15 frames a second looks good but may miss some details that would provide help in theft, slip and fall, and many other incidents. Unless storage time is a real problem we recommend 30 fps. Basically, more frames means more pictures and more pictures means more data, also means less record time.
At last, how many days can record of 500GB DVR with 4 camera at CIF record mode ?
For CIF record mode, each camera take almost 300M per hour, then 4 camera X300M= 1.2GB, 500GB DVR approximately 18 days.

How to create a static Ip address for your dvr

You must choose "Static" on the DVR

For example, you first choose DHCP on the DVR to automatically obtain the proper settings such as DNS, Subnet Mask Default Gateway etc... Write these down. Then choose Static IP on the DVR and manually enter all of the DHCP settings "except the IP Address" The IP address needs to be changed to an IP OUTSIDE of the range of the DHCP such as 103 if the DHCP is Default Gateway - 192.168.2.1 / Beginning 192.168.2.2 with a maximum of 100 this would leave 192.168.2.2 to 192.168.2.102 as the range for DHCP leases. You need to choose a Static IP outside of this range such as 192.168.2.103to ensure the IP does not conflict or change when the DVR reboots or another CPU is issued an identical IP address. You can get this information from the router itself while logged into the main page. It tells you the maximum, just need to know a little math =) To ensure the Static IP you choose is not in use go the the START Button and click Run and Type CMD or Search and Type CMD. On Run it will pop up, on Search you have to right click CMD and choose "Run as Administrator" after Windows finds it. Type PING*space*192.168.2.XXX it should NOT Respond. If it does that IP is in use and you have to choose another. (Do this before you Port Forward). You may need to unplug the DVR from the Router while you do this, then plug it back in.

Each Port needs to be forwarded to the Chosen Internal Static I

Remember to forward ALL ports required. Sometimes you can have more than 1. Example (Port 9000 - Media) (Port 7777 - Command) (Port 80 - HTTP) (Port 0100 - Mobile) Refer to your DVR manual under "Network" for specifics. Remember the IP needs to be Static on your DVR.
Go to portforward.com for a list of routers and specific step by step directions on forwarding ports on your router.

Adjust the Bandwidth Setting

Ensure that the Bandwith setting on your DVR is set at or below the maximum allowed bandwidth for the DVR locations ISP. Example: Contact the ISP and get the Bandwidth setting (256k, 384k, 512k etc.) and set the DVR at or below this number or it may not load at the offsite location. Some DVR's only allow access to this setting via the web interface. Access it locally while plugged directly into the router by typing in the DVR's Static IP in you web Browser (usually only Internet Explorer works) to access the DVR and change the setting there.

Operating System Issues

Most DVR's do not work with MAC unless there is a parallel Windows Operating System installed and Internet Explorer is used.

Bridging the Router

It is suggested that the Router have a "Full Bridge" to the Modem. If you can plug directly into the Modem and access the Internet you are halfway there. Contact your ISP and have them remotely access your "Laptop" that is plugged directly into the Modem. They need to do some specific setting adjustments this way. They will guide you through the process of setting the router up also. Just make sure you insist on a "Full Bridge" between the Modem and Router and ensure that you can access at least 3 websites from the Modem "with the Patch Cable plugged in" YOU MUST USE A LAPTOP to do this.

Which is better Cat5 or RG59?

Which is better, Cat5 or Coax ?
The answer is neither. Each has it’s own benefits. For simplicity coax wins, it is also a more rugged solution and for self install comes in pre-made lengths, often with the DC power attached.
Cat5 is particulary well suited to situations where you need ot run a number of feeds to the same place. We had a customer who had a DVR located in his main workshop and office but who had a satellite workshop some distance away in the same building where he wanted to install a number of cameras. In this instance Cat5 was perfect. Run a 4 camera feed in a single wire from the DVR to a distribution hub in the satellite workshop and feed the cameras into the distribution hub. It saved running 4 long coaxial cables. The cameras were all powered locally.
That’s the one downside of cat5 cable, it’s relatively small cross section makes running power over long distance impractical if voltage drop is to be avoided, particularly with powerful infra red cameras.

Video Surveillance trends to look out for in 2014

IHS has come out this its 2014 prediction of video surveillance trends to look out for in 2014. Of particular interest, is what IHS calls the "crowd sourcing" of video data collection, ie they way video was collected and analyzed from many different sources following the Boston Marathon bombing. There's been a ton of talk about the legacy of how that tragedy was handled, and I think IHS has summed it up well and obviously pointed out a trend to watch.
In terms of products that are selling and vertical markets that are hot, IHS points to "fixed-dome and 180/360 degree network cameras," and, not surprisingly, city surveillance and maybe a less-obvious one--utilities/energy sectors.
Thermal cameras are getting some attention. This is a topic we've written about, most recently in a market trends report.
Are you paying for video analytics? According to IHS, you will be if "the end-user needs advanced reliable analytics." Doesn't everyone need reliable analytics?
Audio capabiities will come into play more in 2014 too, IHS says.
Below is an overview of the trends that IHS put out yesterday:
IHS has recently released its fifth annual white paper on the key trends for the video surveillance industry. 2014 is all set to be another exciting year for the industry, with big data, thermal cameras, embedded audio capabilities and the rise of the cloud in China just a few of the trends to watch out for during the next 12 months.

The trends are:

1. Video Surveillance: The Star Markets for 2014
2. Big Data: Crowd Sourcing Video Surveillance and Social Media Analytics
3. Cloud Based Video Surveillance Opens Markets in China
4. Thermal Cameras Hit the Commercial Market
5. Panoramic Cameras – Providing the Full Picture
6. Power over Ethernet: Watt’s the Story?
7. Is it Time for a Different View on Live Video and Mobile Access?
8. Video Analytics Market Reaches a Fork in the Road
9. Security Cameras to Make Some Noise in 2014
10. Video Surveillance Vendors Enter New Markets


1. Video Surveillance: The Star Markets for 2014

IHS has been researching the video surveillance equipment market for more than 10 years. During this time, the market has grown quickly, most years at a double digit rate. The year 2014 will be no exception. IHS forecasts that the global market will grow by more than 12 percent. Within the global market, IHS has identified fixed-dome and 180/360 degree network cameras as the fastest growing product segments, and the city surveillance and utilities/energy sectors as the vertical markets to watch.

2.Big Data: Crowd Sourcing Video Surveillance and Social Media Analytics

The prevalence of smart phones, with cameras and internet connectivity—combined with social media apps such as Vine or Instagram—has led to the first “crowd sourced” data collection for an investigation in 2013, following the Boston Marathon bombings.

Now that the trend has begun, IHS predicts it is likely that police forces will increasingly request, and need to manage, crowd sourced video surveillance data. While this will allow law enforcement agencies to react more quickly, especially with the use of social media monitoring, it will also create data analysis and manipulation challenges. Meeting these challenges will provide systems integrators and software vendors with a new opportunity to create solutions that improve police incident responses in 2014 and beyond.

3. Cloud-Based Video Surveillance Opens Markets in China

In China, the concept of the cloud is becoming increasingly popular, especially as the telecom infrastructure matures. As network bandwidth improves and network product pricing declines, cloud based video surveillance solutions are drawing the attention of more suppliers. While a cloud based solution is not a compulsory choice, it does represent a great opportunity to leverage the massive demand for civil video surveillance.

With more attention and an increasing customer base, IHS predicts that cloud based video surveillance solutions will be defined by the value created in the applications it offers to customers. With more than 1 billion potential users in China, getting the right mix of product and security features will be a successful combination.

4. Thermal Cameras Hit the Commercial Market

IHS forecasts that the video surveillance product market that will see the largest average selling price (ASP) decline during the next few years will be the un-cooled thermal camera market. While the number of un-cooled thermal camera units shipped to the commercial security industry suggests that the market has not yet been commoditized, increased competition, new products and new end-user markets will mean 2014 is a breakthrough year for the technology.

5. Panoramic Cameras – Providing the Full Picture

The big video surveillance camera category winner in 2014 will be 180/360 degree panoramic network cameras, with global unit shipments forecast to increase by more than 60 percent year-on-year, according to IHS. In particular, the cameras are predicted to gain market share in verticals such as retail, airports and casinos, where monitoring wide indoor areas is a key requirement of the video surveillance system.

6.     Power over Ethernet: Watt’s the Story?

As the transition towards network video surveillance continues, increasing focus is being placed on the supporting network infrastructure, and a crucial element to this is power. Recent developments in power over Ethernet (POE) standards and products make the technology a much more viable option for security managers. Looking forward, IHS expects that security camera manufacturers will expand and develop their portfolios of low-powered cameras to conform to the POE+ standard. Technologies that overcome the distance limitations of Ethernet and POE also will find general market acceptance.

7.     Is it Time for a Different View on Live Video and Mobile Access?

Following the events of the school shooting in Sandy Hook 12 months ago, there has been renewed focus on the idea of facility security managers securely sharing live video footage with law enforcement in the event of an incident. The technology needed to provide this already exists, yet issues over ongoing cost—and more importantly, who pays for the system—have meant that market penetration has been limited. However, with costs dropping and a refocus on protection of assets of both the physical and human kind in the post-Sandy Hook era, 2014 could be the year where live streaming of video surveillance to law enforcement becomes the norm.

8.  Video Analytics Market Reaches a Fork in the Road

For some time now, video surveillance device vendors have been embedding low-end video analytics applications in their devices and offering them as “free” features. A question has therefore been raised: Will there continue to be a market for video analytics, or will all applications simply be offered for free? As the market reaches this fork in the road, it’s clear that vendors can no longer charge for basic algorithms. That said, in 2014, the market for video surveillance devices with chargeable VCA will remain a viable market in applications where the end-user needs advanced reliable analytics.

9.  Security Cameras to Make Some Noise in 2014

More than 70 percent of network cameras shipped globally in 2013 had either unidirectional or multidirectional audio capability, according to a new analysis from IHS. However, the consensus from security systems integrators is that these capabilities are rarely used. Nonetheless, with increasing awareness of embedded audio analytics and even sound source localization, market penetration could be about to rise. With much of the technology already available and the constant need to differentiate products and increase system efficiency, IHS predicts that the market will see greater emphasis on the audio capabilities of video surveillance systems in 2014.

10. Video Surveillance Vendors to Enter New Markets

Contrary to popular belief, the physical security market is not consolidating, at least not in the near future. However, video surveillance vendors are beginning to look at new markets as they invest the profits made from years of fast market growth. Following the announcements of new products from companies like Milestone Systems and Axis Communications and new services from Hikvision and Dahua during 2013, IHS expects this trend to continue into 2014 with more new product and service announcements from network focused security companies, as they seek to add new revenue streams to their portfolio.

Is a bullet camera better than a dome camera

There is a wide range of security cameras on today’s market. You can pretty much get anything you want like a PTZ camera, dome camera, IP camera, box cameras and even bullet cameras. But which one is the best? Determining what the best camera is is all very personal. It depends on your situation, what you want monitored, how much you are willing to spend etc… However, when people compare cameras they tend to compare two types specifically, bullet and dome cameras. So which is better?
Bullet cameras have long since been the favorite among consumers. Back in the day, c-mount cameras were the most widely used and could be seen being used by government organizations, celebrities and for private security. Bullet cameras really took off back in 2000 but, like dome cameras, they have always been around. Dome cameras have been popular in places like malls and other commercial settings.
But how do you determine which one is better? Are there any real, overwhelming differences between the two? The answer to that question is no. They are made up of primarily the same things including a lens, circuit board, chip-set and casing. But as to which one is better, it really depends on your situation and how you wish to use them.
According to the opinion of one of our security camera professionals here at our store, dome cameras are tentatively better. His reasoning is that with a dome camera, your camera is more compact and easier to conceal . Our professional also states that dome cameras are easier to set up and install than bullet cameras. Wiring and mounting for a bullet or dome camera is simple and easy.
Choosing one over the other ultimately depends on your situation and what you want to record.

How to install a Security Camera System

Rain, sleet, snow, wind and even high temperatures can all interfere with the workings of a surveillance camera if it's not weatherproof. Here's how to install weatherproof surveillance cameras.
Instructions
1.  Create a surveillance diagram of the exterior of your property and plan where to position your cameras. Shade any areas that will fall in the line of sight of the cameras. (The camera's range should be indicated in the device's literature.) Remember to incorporate the total area of sight if the camera can pan.
2. Install weatherproof surveillance cameras by securely attaching the mounting apparatus to the exterior walls. Use screws appropriate to the surface you are working with. You want the camera to be as stable as possible to prevent it from falling down in high winds.

3. Attach weatherproof wiring to the cameras. Even wireless cameras typically need wiring to run to the power source and the antenna.

4. Run wires for wired cameras (or install the receiver if using wireless cameras) to the recording or monitoring devices. Protect the wires from being cut by running them overhead or installing a protective casing around them.

5.Install and set up the program to monitor your exterior cameras. You can program when you want to record and set up remote monitoring via the Internet. You may have to purchase additional software.

Understanding what a Varifocal Security Camera is

What Is A Varifocal Security Camera?
One of the best values in security cameras are those equipped with a varifocal lens. These lenses come for a variety of camera styles with the two most popular choices being very-focal lenses on dome cameras and box cameras.
Varifocal Lenses Are Great For Businesses That Plan to Expand
These lenses are perfect in many situations. The first situation is a business that plans to expand to a new location someday. When a camera is equipped with a varifocal lens, then the business owner can easily move the camera to a new location. Adjusting the camera at the new location can easily be accomplished just by adjusting the focal length of the lens.
Varifocal Lenses Are Great For Homeowners On The Move
Many homeowners enjoy this benefit as the camera equipped with a varifocal lens can easily be packed up and moved to a new location. The homeowner may choose to move the camera when they move to a larger property or a smaller property and the lens can easily be adjusted to the new location.
Varifocal Lenses Provide Flexibility
The varifocal lens also makes a great choice for business owners and homeowners who may not be exactly sure what size of lens they need. With fixed distance lenses, the business owner or homeowner must guess at what length of lens that they need. If they guess wrong, then the whole unit must be returned if allowed or sold as a second hand camera costing both time and frustration.
Change Location Of Recording Without Anyone Knowing
These lenses are also super at changing what the camera is recording without having to change the camera position. Without moving the camera, it is possible to record many different situations. This is particularly useful in a commercial setting when you may want to watch one situation one day and another situation the next. The lens will also allow you to change the angle at which you see a situation.
Many people are familiar with the zoom feature of a digital camera and the varifocal lens on a security system works very similar to the lens on that camera. Just like having more zoom ability on a digital camera, the wider the range of objects this camera can be focused on, usually by turning a knob on the outside of the camera’s housing.
Dome Varifocal Security Cameras
Dome security cameras can be equipped with varifocal lenses for both indoor and outdoor use depending on the housing chosen. The most common varifocal lens on dome cameras is the 3.6 mm to 8 mm lens. Remember that the wider the range of numbers the more choices you have when using the camera. Cameras with a 3.6 mm to 8 mm lens have a maximum angle of viewing of 79.22 degrees and a minimum angle of viewing of 33.4 degrees. It is important to look at the distance that you want to install the dome security camera from where the action will likely occur. The smaller the millimeter number the closer the camera will need to be to the action, but the camera will have a wide area where it will record the action. The larger the millimeters number the smaller the area that the camera will record the action, but the action can be recorded from further away.
In order to determine the right focal length consider these facts. If you are watching a parking lot with a lower millimeter lens setting, then you will be able to see about six cars parked about 15 feet away. You will be able to see the make and model of the car, but very little else. If you use a camera with a higher millimeter lens, you will be able to see more details, such as car license plates and face details, but you will be able to see very little space.

Infrared Dome Security Camera with Varifocal Lenses
These cameras can be equipped with different types of operating systems. For example, many business owners and homeowners choose infrared security camera with varifocal lenses. These cameras offer the owner the ability to use the camera when no light is available. These cameras emit a small LED light that provides enough light for the camera to operate. It is important to look for a camera with IR power that matches the focal length, as the lights will only broadcast so far.
Day/Night Dome Security Cameras with Varifocal Lenses
Others choose day/night cameras with varifocal lenses. These cameras are equipped with special mirrors that collect any available light and use it to produce the footage. As more light is available, the camera will take colored pictures, but in low light situations, the pictures will have a green tint.
Daytime Dome Security Cameras with Varifocal Lenses
These cameras operate with the available light, so if there are no light these cameras will not operate. They are great in many situations where light is available all the time. An example would be inside a retail store where the lights are left on even at night.
Other Considerations When Buying Dome Security Cameras With Varifocal Lenses
Whichever dome security cameras with a varifocal lens the user chooses to buy, the buyer needs to think about other aspects. The buyer needs to think about how the footage will be viewed. There are several viewing options including a dedicated VCR, connecting it to a computer monitor or watching it on a smart phone. It is also important to consider who will monitor the footage. Some business owners will choose to monitor their own, some will assign a staff person to do this job and others will hire an outside company to do the monitoring.
Resolution on Dome Security Cameras with Varifocal Lenses
The buyer of a security system will want to consider the security systems resolution. This is measured in either TV lines or in megapixels. The higher the cameras resolution, the better the details that can be seen in the footage. The colors will also be truer to real life. A 1.2MP camera has 3.5 times the resolution of an analog camera in its largest format. Therefore most users find megapixels cameras the better buy.
Sensors on Dome Security Cameras with Varifocal Lenses
A very important consideration when buying a dome security camera with varifocal lens is the size of the sensor. The smaller the sensor, often called a CCD chip, the narrower the angle of view. Sensors in these cameras usually come in four different sizes, which are ¼ inch, 1/3 inch, ½ inch and 2/3 inch. If you choose a camera with a ¼ inch sensor then the maximum angle of the field of view is 57.77 degrees and the minimum field of view is 22.62 degrees. If you choose the 1/3 inch sensor, then the maximum angle of the field of view is 79.22 degrees and the minimum is 33.4 degrees. If you choose the half-inch sensor, then the maximum angle of the field of view is 95.63 degrees and the minimum field of view is 43.6 degrees. When you choose the largest sensor, the largest field of view is 113.22 degrees and the smallest field of view is 57.62 degrees.
Varifocal Lens Box Camera
Many homeowners and business owners prefer box cameras. These cameras are great because they deter many criminals because of the mere sight of the camera. The most common varifocal lens on the box camera is the 3millimeter to 15millimeter. This gives the user a wide range of angles to choose from when installing the camera inside or outside in protective housing. Just like with the dome cameras, varifocal lenses on box cameras smallest settings give the widest field of view with 15 millimeters giving the narrowest point of view.
Varifocal Lens Box Camera Sensors
It is important to consider the sensor when buying a varifocal lens box camera sensor. Again, like with the dome security camera the user generally has four choices. It is important to notice that the sensor controls the distance the camera can be placed from the target.

Varifocal Lens Bullet Camera
Bullet security cameras can also be equipped with varifocal lenses with the most common being 2.8 to 10mm. These cameras can also be equipped with the four different size sensors. It is important to consider the different combinations for this camera.
Costs
Most varifocal lenses cost about 20 to 30 percent more than a fixed lens camera, but consider the flexibility that is afforded with these lenses. One can move the camera to accommodate different situations. One can adjust the length of the lens to get the best picture. Furthermore, a person can buy cameras with different sensors to further expand their flexibility. Making sure that you buy the best camera for your money will assure that you are happy with the choice that you made.
The best process to use when choosing a camera is to choose the location that you want to put the camera in and then choose the style of camera that you want to install. Next, consider buying a camera with a varifocal lens. Then choose the size of sensor that is best for what you want to accomplish now and in the future. Finally, consider the resolution you want in the camera.
