For the novice, security cameras choices may seem confusing. One question often asked by customers is what is a Vari-Focal Lens? There are two basic types of CCTV lenses. You can either get a fixed lens,
or a vari-focal lens. A fixed lens has a set aperture that cannot be
changed. They can be used for overviews or for close up detail, but they
cannot be used for both or be adjusted. When you purchase a fixed lens,
you will want to use a lens caluculator to make sure you are getting a
lens with the correct aperture since you cannot adjust it once you
install it.
A Vari-Focal lens is usually more expensive, but it allows you to
adjust the aperture on the fly. This leaves less room for error and
would also allow you to make changes to the view at a later date.
Varifocal lenses come in various apertures. These are the general lense
sizes. 2.8-12mm lens, 3.5-8mm lens, 6-60mm lens, and 5-100mm lens. The
larger the aperture number, the more zoomed in the image will appear and
the greater detail that can be captured. The smaller the aperture
number, the wider the view and less detail will be captured. Keep in
mind that all lenses have a give or take. The larger the aperture, the
greater the detail, but you will get less of a field of view, so the
image will be narrower. The smaller the aperture, the wider the field of
view, but the less detail you will get.

The True value of a Hybrid NVR
Hybrid NVR/DVRs are appliances (purposed built computers) that
can simultaneously support IP cameras and directly connected analog
cameras. This provides simplicity and flexibility. Customers can start
with their existing analog cameras and slowly migrate to IP.
Specifically, unlike a 'pure' NVR, a hybrid NVR/DVR eliminates the need
for a separate video encoder when connecting to analog cameras.
Hybrid NVR/DVRs are now being offered by almost all of the traditional DVR companies. However, many have questioned whether this meets a customer need or is done simply because it is easy for the traditional DVR companies to do.
Nevertheless, the hybrid NVR/DVR is quite legitimate and plays a critical role in very common scenarios in video surveillance:
A main benefit of a pure NVR is consolidation of video management and storage functionalities. Rather than managing video in chunks of 16 or 32 across potentially dozens of appliances, centralized servers and storage clusters can be used. These servers and storage clusters can reduce equipment cost, power consumption and service costs. Indeed, main of the early adopters of pure NVRs and IP video systems did so because of this advantage.
The biggest challenge in consolidation is bandwidth availability. Consolidating requires video feeds from various parts of a facility/facilities be transmitted to a central location(s). To do this, requires sufficient bandwidth. Inside the local area network (usually inside a building), bandwidth availability is plenty and fairly inexpensive. However, in the wide area network (usually between buildings or campus), bandwidth is scarce and quite expensive. To centralize video management and storage across the WAN could easily cost hundreds or thousands of dollars per month, negating the benefits of consolidation.
In many distributed facilities with 4 to 32 cameras, organizations will have to manage and store their local feeds in their local premises. This is, of course, not new as it is the common practice with DVRs. However, it does affect the NVR business case and create incentive to choose hybrid NVR/DVR systems.
Economic Comparison of Hybrid DVR/NVR to pure NVR
When you have less than 32 cameras and you need to store and manage those cameras locally, the economics of hybrid NVR/DVRs are far better than pure NVRs.
A mid-tier 16 to 32 channel hybrid NVR/DVR costs about $6,000 to $8,000 (using online Google pricing for all estimates). The hybrid NVR/DVR does encoding, storage, management and serving of the video, all in one, with minimal on-site setup and configuration.
By contrast, a pure NVR solution can cost 20% – 50% more than a hybrid system and is more complex to setup and maintain. The additional costs come from having to (1) purchase standalone encoders to convert the analog cameras to IP ($200 to $300 per camera), (2) purchase software licenses for the NVR($100 to $150 per camera) and (3) purchase a PC/server with storage ($75 to $125 per camera). Additionally, the server needs to be set up, software loaded, OS tuned, encoders configured and connections established between encoders and NVR. It also takes more space, more IP addresses and because there are now multiple systems, increases the risk of integration or future service issues.
The NVR approach is much more complex and time consuming than the comparative hybrid NVR/DVR which is relatively plug and play. In a large scale environment where 100s of cameras were being consolidated, the cost savings often justify the additional complexity and setup time. However, in a small setup, the costs are quite significant.
Hybrid DVR/NVRs Provide a Smooth Transition
For any given customer, the most attractive hybrid DVR/NVR will be the unit from their existing DVR supplier. Even if the customer does not especially like their DVR vendor, all of their staff is trained on using that DVR's client software. Moreover, often, all of the DVRs are from one vendor, so the staff never has to worry about which software client to use. The same client software for the DVR can usually be used for the hybrid systems. This makes the switch seamless and transparent to the users. Customer are willing to switch but when it's close, the comfort of the staff is a major factor in sticking with existing processes and products.
What's the Downside of Hybrid DVR/NVRs
The biggest downside of Hybrid DVR/NVRs is that many are not truly hybrid. A genuine hybrid would be equally flexible with IP and analog. Mixing and matching many combinations of analog and IP would be standard. Supporting a variety of IP and megapixel cameras would also be standard. Exacq is a good example of a true hybid. The problem is a lot of so called 'hybrid' systems offer only token support for mixing and matching and for different IP cameras. One common technique is to offer only a few additional IP cameras, constrained to 1 or 2 IP suppliers, in addition to the 16 analog inputs. GE's Symdec is an example of a "fake" hybrid. Hybrid systems are supposed to give you flexibility to grow into IP. This approach is more of a trick than a benefit.
The other downside of Hybrid DVR/NVRs is that they may not offer the same advanced functions as NVRs. Though individual units certainly do not, most mainstream DVRs support the same type of advanced functions as NVRs do. For more information, examine my review on how DVRs have been catching up to NVRs. Buyers should examine this point but most mainstream hybrid systems should be quite close to NVRs.
Conclusion
For many mainstream security buyers, hybrid DVR/NVR systems are going to be the best choice. The lower cost, easier deployment, and lack of client changes needed will make the hybrid DVR/NVR very attractive for applications needing recording of moderate camera counts at distributed facilities. Buyers should carefully examine how hybrid the system truly is and how the functionalities compare to pure NVRs but may conclude that hybrids work best for their needs.

- 80%+ of cameras today are analog and most of those cameras have many years of service left in them.

What’s The Difference Between Analog And IP Cameras?
When choosing security cameras for your home or business, you’ll
notice a lot of talk about the differences between analog cameras and IP
cameras. Both types of cameras
work well in either personal or business security scenarios. An analog
camera feeds your security images directly to a television, VCR, or DVR. An IP, or network camera feeds your security images directly to
a Web server. Whether an analog or IP camera is best for you depends
upon your individual security needs, so I’m going to list some
differences between the two to help you decide on your security camera.
This being said, the IP models are generally easier to install than analog units are. They feed the security image directly to Web server, so any wiring you need is likely present in your home or business for your computers. Therefore, the cameras themselves may be more expensive, but the installation and wiring fees for an analog camera just might offset the difference in camera cost should you choose an IP.
With this in mind, if you are securing your home, for example, and you would like to spare your neighbors the annoyance of high-voltage mercury lighting around the perimeter of your property, you might do better with an analog camera. If you’re securing your business, which has lighting all around the property to keep it bright throughout the night, you would do fine with an IP camera.
In terms of motion sensitivity, however, an analog camera is far more stable. This camera model might not project clear images at extended distances, but it can handle the shaking of high winds or even an earthquake better than an IP camera. Your image will stay truer on a disturbed analog camera than a disturbed IP one.
As I said at the beginning of the post, analog camera technology is older, and the maximum amount of megapixel resolution an analog camera has is 0.4 megapixels. An IP camera has as much as 10 megapixel resolution, so your image will be much clearer with an IP camera. This will, of course, also increase the cost of the camera.
An IP camera system can be hard-wired or wireless, and the image feeds to a network server. The server to which the feed is transmitted can be accessed by any electronic device with Internet capabilities. For example, if you have your home or business secured with IP security cameras, all you would need to do is log in to the server hosting your camera feed and voila! Instant security images on your computer, smartphone, notepad, or other mobile device.
An IP security camera encrypts your security feed prior to sending it to the network server. It does this for several reasons, including compressing the data into a smaller size and securing it for transport over the Internet; therefore, if you are concerned about the security of your security images, you’ll probably feel more comfortable with an IP CCTV security system than an analog one.
As you can see, there are some significant differences between an analog and an IP security camera. The type of camera you choose really does depend upon your individual security needs. If you are securing your home, and simply want a simple, inexpensive system, analog might be the way to go. If you’re securing your business and have an expansive area to secure, you might find IP a better solution.
Expense
Let’s talk about budget first, because that is generally a primary concern for anyone looking to install a new security system or enhance an existing one. Analog cameras are cheaper than IP cameras. The technology behind the analog security feed is tried, true, and quite old – about 50 years old to be exact. As such, these cameras cost less than the newer and more technologically advanced IP models.This being said, the IP models are generally easier to install than analog units are. They feed the security image directly to Web server, so any wiring you need is likely present in your home or business for your computers. Therefore, the cameras themselves may be more expensive, but the installation and wiring fees for an analog camera just might offset the difference in camera cost should you choose an IP.
Lighting
Cost aside, another important consideration for your CCTV security cameras is lighting. I stress to my customers daily that security cameras do you no good if you cannot see the images they are projecting. An analog camera works very well at recording images in many different hues of light. An IP camera performs much better in well-lit conditions.With this in mind, if you are securing your home, for example, and you would like to spare your neighbors the annoyance of high-voltage mercury lighting around the perimeter of your property, you might do better with an analog camera. If you’re securing your business, which has lighting all around the property to keep it bright throughout the night, you would do fine with an IP camera.
Distance
Another thing I stress to my customers is distance. In this particular case, analog wins again for home lighting, whereas IP wins for business property. Analog cameras record well in light, but lose clarity the further away the image. IP cameras maintain clarity at longer distances, so they work well for securing larger areas, such as parking lots or warehouses, for example.In terms of motion sensitivity, however, an analog camera is far more stable. This camera model might not project clear images at extended distances, but it can handle the shaking of high winds or even an earthquake better than an IP camera. Your image will stay truer on a disturbed analog camera than a disturbed IP one.
Clarity
Clarity at a distance isn’t your only concern, however, and I often recommend IP systems to my customers who desire a clearer and sharper picture. This is where the differences in technology come into play, and one of the reasons why IP cameras are more expensive than analog cameras. Just like pictures taken with digital cameras, the more pixels the better the clarity.As I said at the beginning of the post, analog camera technology is older, and the maximum amount of megapixel resolution an analog camera has is 0.4 megapixels. An IP camera has as much as 10 megapixel resolution, so your image will be much clearer with an IP camera. This will, of course, also increase the cost of the camera.
Projection Feed
I briefly touched upon it in my introduction, but let’s talk a little bit more about the actual projection feed of an analog versus an IP camera. The security systems you see monitored on TV screens by security guards are generally analog CCTV systems. These cameras are hardwired into a recording device, such as a VCR or DVR, and are constantly recording and projecting the security images onto the TV screen.An IP camera system can be hard-wired or wireless, and the image feeds to a network server. The server to which the feed is transmitted can be accessed by any electronic device with Internet capabilities. For example, if you have your home or business secured with IP security cameras, all you would need to do is log in to the server hosting your camera feed and voila! Instant security images on your computer, smartphone, notepad, or other mobile device.
Security Camera Security
It might sound silly to talk about security camera security, but let’s do that for just a moment! As I explained above, your analog security camera is feeding the images directly into a recording device. This makes your security feed susceptible to anyone with the capabilities of getting their hands on your tapes, or DVR recording units.An IP security camera encrypts your security feed prior to sending it to the network server. It does this for several reasons, including compressing the data into a smaller size and securing it for transport over the Internet; therefore, if you are concerned about the security of your security images, you’ll probably feel more comfortable with an IP CCTV security system than an analog one.
As you can see, there are some significant differences between an analog and an IP security camera. The type of camera you choose really does depend upon your individual security needs. If you are securing your home, and simply want a simple, inexpensive system, analog might be the way to go. If you’re securing your business and have an expansive area to secure, you might find IP a better solution.

New trends in Security Cameras
The market for networked digital IP
security cameras is growing rapidly as more companies seek affordable
ways to protect their key assets, including personnel, merchandise and
real estate. Responding to these needs, IP security camera manufacturers
have worked hard to find ways to improve performance while controlling
costs.
Together with high-quality optics and advanced image processing, one of the key aspects of digital camera performance is resolution. For various reasons, conventional security cameras have been limited to 640 x 480 pixel VGA resolution and this has caused frustration with many users who require more detailed images for analysis. Fortunately, recent advances in CMOS sensor technology have made it more economical than before to offer "megapixel" IP security cameras, which provide approximately four times the pixel count and twice the linear resolution of conventional VGA cameras. At the same time, advances in compression algorithms have resulted in more efficient data storage with minimal loss of image quality. These new algorithms enable users to manage the increased volume of image data produced by megapixel IP security cameras more effectively.
A good-quality megapixel IP security camera offers multiple resolution and data compression options to suit the needs of various users. In addition to megapixel resolution for detailed image analysis, many users require VGA resolution for low-cost monitor display and QVGA (320 x 240) or even QQVGA (160 x 120) resolution for use on mobile devices such as smartphones.
The two dominant forms of data compression in modern IP security cameras are Motion JPEG and MPEG-4 or its subset, H.264. Motion JPEG is best for applications where there is a need to extract individual video frames for detailed analysis, while MPEG-4 offers superior data compression for video data storage. The better megapixel IP security cameras on the market today provide simultaneous output of Motion JPEG at a variety of resolutions and MPEG-4 or H.264 video.
When it comes to the imaging excellence of high-quality IP security cameras, megapixel resolution and highly efficient image compression are only the beginning. These cameras must also be able to produce crystal-clear, low-distortion images from corner to corner in conditions ranging from extremely low light to extremely high-contrast lighting. This level of performance requires first-rate technology in both optics and digital image processors. Manufacturers that produce these key components in-house are a step ahead of competitors who have to purchase them from outside suppliers. In-house manufacturing ensures better performance because key components such as lenses and image processors can be built to work in total synergy with other camera components.
For most outdoor security applications, a high-power zoom lens is best. The greater the zoom range, the easier it is to obtain close-ups of crucial image details such as license plates or facial features. Conversely, space is at a premium in many indoor applications. This requires a sophisticated compact lens that combines clarity and low distortion with an ultra-wide angle of view.
Good image quality in low light requires many specialized camera features. Among these are a large-aperture lens, a high-sensitivity image sensor and an image processor that's capable of preserving detail while reducing noise. With these elements in place, the best megapixel IP security cameras can achieve excellent quality in color at light levels as low as .03 lux. For black-and-white images, good quality has been achieved at light levels as low as .001 lux. And for high-contrast lighting conditions, new algorithms such as those employed by Canon's Smart Shade Control feature allow selective brightening of shadow areas in the image without losing detail in brightly-lit areas. This capability is invaluable for many environments that combine outdoor and indoor illumination in a single scene.

Home Security trends for 2014
For decade’s analog cameras reigned supreme in terms of security.
However, that is starting to change and expect 2014 to be the peak of
this.
For the first time, experts project sales in digital cameras to surpass analog in 2014. Network cameras generally have more features and are more expensive than analog cameras. Despite less than 20% of cameras shipped in 2012-13 being network cameras, the revenue exceeded those of analog cameras.
The market is demanding for a better quality image. High definition is no longer a luxury, it is EXPECTED when looking to purchase any sort of video surveillance camera equipment. It wasn’t until recently that manufacturers were producing cameras that recorded in high definition. Consumers want the best quality video possible so they can clearly see what they are capturing.
Before now, small, discrete mega pixel Hi-Def cameras were not as widely available. Either the cameras were large and not discrete or small and standard definition. These covert cameras that could record high quality video seemed impossible to find. However, now consumers can have the best of both worlds. Manufacturers have realized that the market is certainly trending towards covert mega pixel Hi-Def cameras that are small and are high definition, so they can capture the best quality video. Smaller cameras create unlimited opportunities for types of covert cameras including clocks, smoke alarms and a variety of other common devices. IP video on small discrete security cameras are becoming more common. That trend is expected to rise in 2014.
In addition, the popularity of panoramic cameras has greatly risen. They have gone mainstream and are quite common everywhere. There are a variety of products in various shapes and sizes, available to the consumer who is looking for a panoramic camera that has high quality HD video.
In summary, it wasn’t until recently that the mega pixel market has demanded for small and discrete cameras. Surveillance security cameras that had mega pixels in the past used to be very large and revealing. In the security world, smaller may be better because it is more discrete and allows manufacturers to hide the cameras inside home devices.

Choosing a Monitored Home Security System
Price is obviously a driving factore in most consumer security system
choice. But a low price on a system that does not adequately meet
your families security needs is worth less than nothing.
Prominent companies that offer Landline Monitoring:
Pure internet or broadband alarm monitoring means the alarm signal is not converted to a voice signal via VoIP. The monitoring center is sent a signal over the internet that the security system has been triggered. This is a preferable solution to VoIP since the control panel is designed to specifically handle this sort of signal. But the negatives are the dependency of your home network working, and power to house is required.
Communicating with the Monitoring Center: Choosing Cellular, Broadband Internet, VoIP or your Phoneline
In the past just about every security system was dependent on your phoneline. This has now all changed, consumers are abandoning landlines, cellular/gsm technology is mature, and broadband high speed internet connections are commonplace. The most popular choices are cellular and landline monitoring.What is better Cellular or Landline Home Alarm Monitoring?
Cellular monitoring is the best monitoring solution if it is available in your area. A few basic points set it ahead:- The lines cannot be cut. A copper phone line cannot be snipped, a cellular enable control panel with battery backup (or charged batteries) is an independent device.
- No need for a landline. This is also provides ease of setup if you move.
Prominent companies that offer Landline Monitoring:
- ADT (Predominantly Landline)
- Protect America (also has Cellular and Broadband Packages)
VoIp and Broadband Home Security Systems
VoIP shines when it comes to long distance calls, but there are some potential issues when it comes to monitoring your house. Some VoIP companies recommend that they are not used for home monitoring, not all control panels work with VoIp, it is dependent on your home power and internet connection working. This adds many variables and potential weaknesses for monitoring. But it can be viable for low-cost DIY solutions despite VoIPs QoS (quality of service) issues.Pure internet or broadband alarm monitoring means the alarm signal is not converted to a voice signal via VoIP.

But the negatives are the dependency of your home network working, and power to house is required.
What questions should I ask about my home monitoring service?
The type of alarm monitoring as discussed above are a big issue. For prices review our home security system costs page for more details on comparing leasing a system versus buying a system.- What responses are offered? Will I be contacted? Will a local dispatch be contacted? Will the police be contacted?
-
Do I need a contract? Or can I have the monitoring on a month by month basis?
- Not having a contract can result in large savings in case you ever move, or are unhappy with your provider
- What are the maintenance fees? How much is service if the system is at fault?
- Will I receive stickers for all of my doors and window entrances?
What questions should I ask about the security equipment installed in my home?
-
Is the equipment installed proprietary? i.e. Could I used the equipment with other alarm monitoring vendors?
- Proprietary equipment attaches you to that security company as long as you use it. Consider equipment that works accross multiple vendors
-
How update to date is the equipment installed? Is it the most recent version?
- Each year equipment manufactures improve and upgrade products, including features like less false alarms, more efficient power usage, greater reliability
-
Do you have pets? How large are they?
- Systems exist with tolerances based on the estimated weight of an moving object
- Is every entrance wired? (accessible windows and doors)
- Does the system log events? Can I review false alarms? Alarms and other events that occured in the security system?
- This can be of great value for maintenance. Service technicians can read the logs to determine any issues a system may be having.
What about False Alarms?
False alarms are nuisance for home owners, neighbours and potentially police and fire departments. Technological improves are pushing forward in reducing the number false alarms.- "Just Set" features, these indicate to the alarm company that the system had just been armed, this is the most common source of false alarms
- If you have pets does the system allow weight threshholds for detecting intruders.
- A system could be set to overlook detecting signals from a 30 lb object or less. These weights can vary upon your needs.
- Does the system have Company contact delays?
- When an alarm is should provide a gap of 30-90 seconds to allow the homeowner to disable the alarm with contacting the alarm company. This is helpful when you accidentally trip your own alarm.
- Ignoring short momentary breaks in the detection system. Such as any detected breaks less that 0.5s.
- Multi detect systems, requiring multiple sensors to detect intrusion within a set time period.

Understanding the Differences Between Hidden and Visible Surveillance Systems
Buying a security camera system can be a daunting task for a home
or business owner. With the wide variety of video surveillance systems
currently available, it can be difficult to know which surveillance
system is right choice for one's environment.
Visible surveillance systems can be a great deterrent. For example, many retail store ceilings are covered with tinted domes with video camera systems. Some high-volume discount stores have hundreds of these domes scattered across their ceilings. While these systems are very intimidating for would-be shoplifters, they are not always what they seem. In many cases, only a fraction of these security domes actually contain cameras. The rest are designed to act as a deterrent. Since shoplifters can't tell which security domes contain cameras, they will often avoid areas that in a store that contain these security domes.
For business owners with a limited budget, deterrence-based systems can be a great way to save money. However, these systems do have limitations. If a false security dome isn't manufactured to the same standards as a real video surveillance security dome, shoplifters or other criminals may be able to figure out which areas of a store are watched. In addition, a business can expose itself to liability if it detains shoplifters without video evidence.
Homeowners can benefit from visible deterrent systems too. For example, many homeowners use security system yard signs and stickers to warn potential burglars about an alarm system. In addition, some homeowners use fake video camera systems to deter would-be criminals. However, it can be challenging to set up a fake outdoor video camera system in a convincing way. If an exterior video camera system does not appear to have any internal or external connections, criminals may assume it is fake. To avoid these types of problems, fake surveillance cameras must look like they have been professionally installed. For example, an outdoor security camera should not be mounted on a pole or tree with no visible cable.
Hidden security cameras are not an effective deterrent for home or business owners. However, they can be an effective way to document crimes while avoiding suspicion. When using hidden video surveillance systems, it's important to make sure that they create actionable documentation.
If a home or business owner can't act on a recorded surveillance video, it may have limited value. For example, most retail stores have a limited number of hidden cameras for monitoring customers. If a potential shoplifter isn't detained before leaving a store, the video evidence that a store documents may be of limited use as evidence. Because of this, customer surveillance systems usually combine both video documentation and deterrence.
However, hidden video cameras can be useful for documenting actionable crimes. While retail stores usually don't use hidden cameras to monitor customers, they do use them to monitor employees. Lots of cash register systems and cash management areas are equipped with hidden surveillance cameras. In many cases, problem employees at a company will engage in continual theft. By documenting negative employee actions, a company can proactively correct these problems.
In addition, hidden surveillance systems can be a great choice for homeowners. Many homeowners hire maids, gardeners, baby sitters, electricians, plumbers and other professionals to work inside their homes. With a hidden surveillance system, it's possible to detect theft, overcharging, child neglect and other common problems.
