1, the system network formation
According to the specific situation of network construction, network video monitoring system choose to use the following transmission:
Ethernet transmission requires monitoring point Ethernet fiber-optic equipment for the control point image by the network server via the Ethernet interface as the audio uploaded to the monitoring center. Monitoring point or points or to request control center and monitoring center has been connected through Wide Area Network. Image control point network audio server via Ethernet through all levels of routers, switches, or HUB uploaded to the monitoring center.
2, system description
Mainly by the network monitor video and audio front-end server (1 or 3-way or 5 or 7, Road or 9 Road), camera (protective mask, camera, lens, bracket), PTZ decoder, fiber optic transceivers and other major equipment component . Network audio server is a core device in the system, to achieve network, digital processing, it signals the completion of the digital analog video surveillance capture, video compression, surveillance data processing, alarm signal acquisition. Special network by connecting optical fiber transmission to the monitoring center for monitoring the image, you can do central storage; this store makes the network more suitable for video and audio server can respond to sudden emergencies.
Monitoring center can be able to connect to public networks on any computer, by installing monitoring software, remote monitoring center via the IP address of the network video server to manage the remote device and can be assigned user information, allows authorized users to access network audio server and browse through the web-site conditions.
When monitoring the large number (for example: a few thousand points), the server's unique grade control system can provide more efficient management of network monitoring and management system, by Yi Jilie Juti feature server will monitor the network Heli effective organization together.
