The control and the exchange separates, suits the large-scale expansion application. The control, the image, the memory and so on use the international standard technology pletely, is advantageous for the interconnection munication, the overall construction uses the lamination, the opening design, is advantageous for the new technical new service introduction and the fusion. The IP intelligence monitoring construction, the video frequency arranges the decoder, work video frequency memory system as well as work transmission and the key technologies. Introduction supervisory system front end pickup device, image signal work, monitoring control, management, control center and so on each constituent unique feature. The supervisory system carries out practical, advanced, the economy ” this principle of design, embarks from the reality, the system by the onstage pickup device, the backstage system handling equipment and the transmission part constitution, the onstage evidence collection is the system foundation, the background processing is the system core, the transmission part realizes the system real-time function bridge. Key words: Supervisory system Video frequency matrix cut Light end machine DVR hard disk vide 目录摘要................................
