What do I need to do with video surveillance systems?
Video surveillance system consists of real-time control system, monitoring system and management information system. Real-time control system to complete the real-time data acquisition and processing, storage, feedback function; monitoring system to complete the monitoring of all-weather monitoring, multi-operation control point to switch multiple images; management information system to complete the required information collection , Receive, transfer, processing, processing, is the control of the entire system core.
The monitoring system is composed of a large part of the camera, transmission, control, display, record registration. The camera transmits the video image to the control panel through the coaxial video cable, controls the host computer and assigns the video signal to each monitor and video equipment, and can simultaneously input the voice signal to be transmitted into the video recorder. By controlling the host, the operator can issue commands to control the up, down, left and right movements of the pan / tilt and zoom in on the lens, and can be controlled by the host in multi-camera and PTZ Between the switch. The use of special video processing mode, the image can be input, playback, processing and other operations, so that the video effect to achieve the best.
Video surveillance system developed a short period of twenty years, from the 19's 80's analog monitoring to hot digital monitoring and then to the Internet video surveillance, has undergone enormous changes. In the IP technology gradually unified global Today, we need to re-understand the history of video surveillance system development. From the technical point of view, the development of video surveillance system is divided into the first generation of analog video surveillance system (CCTV), to the second generation based on "PC + multimedia card" digital video surveillance system (DVR), to the third generation based on IP network video surveillance System (IPVS).
