The Benefits of Pan-Tilt-Zoom Cameras
What makes the Pan-Tilt-Zoom camera versatile is its ability to be moved during operation. For example, the camera could be placed at the intersection of two hallways. Wiring is run between the camera and a control unit that is stationed near a video monitor. The operator can easily control the view of the camera and survey the entire hallway, depending on the immediate need. This is beneficial when there are different foot traffic patterns that must be closely observed during different times of the day.
When used to monitor a larger area, such as an outdoor lot or a large warehouse, the zoom feature will allow the operator to focus on a more concentrated spot within the total viewable area. This allows for more specific detail to be recorded in the event surveillance material is required for review. The centralized detail will provide a better chance of identifying what actually happened in a specific area.
A Pan-Tilt-Zoom unit also can assist security personnel in locating problems in large crowds. The surveillance operator can move the view to scan a larger area and locate any of the issues that often arise when a large number of people congregate. The operator is then able to notify people in the area to head to the specific location and assist. If the problem moves from the original area, the camera can follow the action and keep the whole scene under constant surveillance. If there are any questions later, the complete scene can be brought up on video, instead of hoping that the stationary cameras caught every aspect of the incident and then piecing the different camera views together.
As with any security system, unless you opt for one hundred percent coverage, which requires many stationary cameras and tends to be very cost prohibitive, these Pan-Tilt-Zoom cameras will allow you to cover a much larger area than with stationary cameras. The ability of these cameras to move with the action allows the operator to pick and choose the areas on which to focus and to assure that the targeted areas are monitored completely.
A PTZ camera can be a huge asset to anyone’s level of security within a well-designed security system. You can create a more complete level of coverage with fewer devices by carefully positioning a couple of these versatile units. If the same area only had static cameras, the coverage would be choppy and more units would need to be installed, giving you only a partial picture of any incident that might happen.
