The network video server (the definition of the network video server) mainly includes three modules: image acquisition, image compression, and network transmission. The image acquisition module realizes the A/D conversion of the video signal; the image compression module realizes the compression coding of the digital signal by a certain compression coding standard; the network transmission module realizes the functions such as the transmission of the compressed data and the setting of the system function.
Simplicity
Through the rapid development of a cost-effective computer communication network to transmit video data to the monitoring center, only a low-cost type 5 network cable is required. If there is a WIFI module inside the video server and the wireless LAN is adopted, then there are five types of network cables. Network cables are saved.
Small model
Generally, it is usually 1-4 channels of analog video input. It will not move more than ten channels of video input like hard disk recorders, and it will not randomly carry hard disks. Placing storage devices at the monitoring center is more conducive to the storage and protection of image data. Save a lot of space.
Easy to upgrade and fully scalable
More cameras can be easily added, and the central server can easily be upgraded to faster processors, larger disk drives, and greater bandwidth in the future.
Powerful central control
An industrial standard server and a set of control management application software can run the entire security monitoring system. Users only need to open a client program on a computer connected to the Internet, and enter the IP address of the corresponding video server inside. Remote monitoring. Any authorized client can directly access any camera or access the monitored image through the central server.
