Building a complex safety system of the object under protection by using the most up-to-date methods and equipment for securing the maximum protection against unauthorized invasion and various threats.
Development of scheme of protection and video-control is made on an individual basis depending on the customer requirements, conditions of operation and in accordance with GOST.
Depending on the type equipment used, the systems of video-control are sub-divided on analogous and digital ones. Analogous systems of video-control are used where it’s necessary to arrange video-control in a small number of rooms, and the information from video-cameras must be recorded on a videotape recorder. For the purpose of safety arrangements the most crucial objects or those distributed on the territory the digital systems of video-control are used, which are, as a rule, integrated in the complex safety systems. Such complexes do fix, record and analyze the information coming from camcorders, readers of the system of control over access, protective and fire safety sensors, and they also autonomously or following instructions by the system operator “take decisions” in respect of protection of the guarded object.
Digital system of video-control is also used in the safety systems of territorially distributed objects as well as in the complexes of safety management of large companies. The functions, parameters and completeness of the video-control system depend on the requirements made by client to the safety of the object (1 – protection of perimeter and adjacent territory, 2 – internal area of premises, and 3 – protection of particularly important objects inside the building). As a rule, the minimum configuration of such system includes the following items: video cameras, devices for processing the video-signals (videotape recorders, facilities for treatment of video-signals [square ware generators, multiplexers etc], recording devices [videotape recorders, video-register, video recorder] and the units for display of video-information [video-monitors].
The larger systems of video-control have additional control and auxiliary devices – a cross-point switch, keypads controlled by video cameras, also video-printers, video-distribution amplifiers, modulators, telemetry receivers and transmitters and other protective devices.
