Video server:
The so-called video server can be regarded as a network camera without a lens, or a DVR without a hard disk. Its structure is similar to that of a network camera, and is composed of one or more analog video output ports, an image digital processor, a compression chip, and a server with network connection function. Simply put, a video server is a dedicated device that digitizes the input analog video signal and transmits it to the network in the form of a digital signal, thereby achieving the purpose of remote real-time monitoring.
