I. Overview of the monitoring system This article refers to the address: http:// The monitoring technology is driven by the rapid development of network technology and information technology, and has been rapidly developing with the sharp increase in the demand for monitoring systems in the security industry. At present, the current status of video surveillance systems is the coexistence of networked multimedia surveillance systems and semi-digital surveillance systems, with networked applications as the main trend. Second, customer function requirements Camera signal 73 Monitoring matrix XW-VDJ16081 Monitoring matrix XW-VDJ96181 16 pairs of reverse data video optical transceivers 3 pairs 8-channel video optical transceiver 1 pair Video 16 in 32 out of the distributor 11 7 channels of 16 hard disk recorders 3D control keyboard XW-VP70305 Achieve function 1. Diagnostic department 3P laboratory separately controls 16-channel camera, data and video are transmitted by 1 to 16 optical transceivers; 2. The first floor monitoring total control room controls the switching of 57 video signals, the control of the ball machine and the authority control of the following three sub-control rooms; 3. A layer of network control room controls the reality of 24 channels of video signals and switches to the local display. The data and video are transmitted by 1 to 16 channels with reverse data optical transceivers and 1 to 8 video optical transceivers; 4. A layer of duty room controls the reality of 16 channels of video signals and switches to the local display. The data and video are transmitted by 1 to 16 channels with reverse data optical transceivers; 5. The outdoor duty control room controls the reality of 16 channels of video signals and switches to the local display. The data and video are transmitted by 1 to 16 channels with reverse data optical transceivers; 6. All video signals are recorded by the DVR; 7. The power supply system is powered by the UPS.
