VIDEO-SURVEILLANCE SYSTEM FOR PERIMETER OF GREAT LENGTH

    The perimeter video surveillance system is one of the most important components of a complex automated security system of a high-security facility.
    Items, the perimeter video surveillance system assigned to solve:
    • detection of unauthorized attempts to penetrate fences and gates;
    • visual verification of an alarming event from the alarm system;
    • control of the situation before and during the response team arrival to the place of the violation;
    • providing access to all necessary users in accordance with the rights granted;
    • event log and video archives keeping;
    • statistics and reports output;
    • human factor influence minimization.
    The video surveillance system can operate independently of other object’s security subsystems, providing visual control over the perimeter 24\7. But the most effective video surveillance system works in integration with the Security alarm system.
    The principle of the system`s operation:
    • The security alarm system based on a sensor cable or various types of sensors determines the location of the perimeter violation on a nominal blocking sector.
    • When an alarm signal appears, the controlled video surveillance camera, responsible for the relevant operating zone, is positioned in the programmed position.
    • On the monitor of the operator`s control panel, a system alarm message is displayed, accompanied by an audio signal. The map (facility plan) displays the location of the violation and streams the video from the relevant camera.
    • The operator treats the alarm message. If necessary, the operator can intercept the camera control and follow the violation subject.
    • All operator actions associated with the appearance and operation of the alarm message, as well as video archives, are stored in the system with an anchor to the date and time. Data from the archive can be viewed or copied during time, according to the designed archive depth.
    The video surveillance system can operate independently of other object’s security subsystems, providing visual control over the perimeter
     
    If the software modules of video analytics are used, the functional of the video surveillance system can be expanded:

    Thus, the perimeter video surveillance system not only performs the video capture but it is also the additional protective barrier.
    When designing and implementing a video surveillance system, high-resolution cameras are often used to clearly identify people's faces and vehicle’s numbers at a rather long distance.
    Also, the necessary options for cameras, that are used to protect the perimeter, are low power consumption, backlight compensation, multiple modes of electronic shutter, and built-in infrared light.
    In order to increase the system efficiency, both stationary and managed CCTV cameras are implemented simultaneously. Stationary cameras with fixed lens provide the system operator with a fixed image from the corresponding perimeter block area.

    Controlled cameras allow to expand the field of view significantly, to monitor the large areas of the protected object, to follow the targets (violators) automatically or in manual mode. It is especially effective to use the controlled cameras with laser or IR illumination, which allows you to abandon the perimeter security lighting.

    Modern threats and challenges dictate to the Customers the use of the latest technical means in the objects’ protection. Such devices should include thermal imaging cameras for video surveillance, the cost of which has recently dropped and become more massive in use.
    They are divided into stationary and controlled. The multisensor optical system is especially effective on the large-area objects, it provides surveillance within a radius up to 12 km. It combines visual and thermal cameras on a single controlled platform. In addition, there is the possibility to install the laser infrared spotlight and a laser rangefinder, which will measure the distance to the object of observation.
