With the development of current network equipment, people have also put forward higher requirements for network monitoring capabilities. The original DVR can no longer meet the needs of all customers, especially in the high-definition era, in the case of transmitting high-definition signals, wireless bridges must be used for transmission, but the wireless bridge transmits signals that are digital signals, then the conversion of this signal must be To achieve through DVS. So what device is DVR and DVS in the end? Xiaobian to briefly explain.
DVR, Digital Video Recorder (Digital Video Recorder), is a digital video recorder. Compared with traditional analog video recorders, it uses hard disk recording and is often called a hard disk recorder. It is also called a DVR. It is a set of computer systems for image storage processing. It has functions for long-term recording, recording, remote monitoring and control of images/voices.
DVS, digital video server, also called digital video encoder, is a professional network transmission device that compresses and processes audio and video data. It consists of audio and video compression codec chips, input and output channels, network interfaces, and audio and video interfaces. , RS485 serial interface control, protocol interface control, system software management and other components, mainly to provide video compression or decompression functions, complete the image data acquisition or recovery, etc., is currently more popular based on MPEG-4 or H.264 image data Compresses the transmission of data and audio data over the Internet.
The difference between DVR and DVS: Video server and DVR device look very similar from the outside. So, is it functionally similar to the shape? In fact, the main difference between a video server and a DVR is that the DVR device can work in stand-alone mode, and the video server must rely on networked software to operate and manage the network video signal. The fundamental difference between them is that the main task of the DVR is to complete video storage in the surveillance network, and the main task of the DVS is to ensure the transmission of video signals.
In fact, the real difference between them is that the DVR can provide users with two interfaces for network switching and local operation. That is to say, the DVR can be disconnected from the network or the computer, and it can be connected to the monitor, mouse and keyboard, etc. to achieve direct video viewing and other operations. Support network services. His advantage is that he can not only monitor the center through the network, but also provide on-site personnel with an operation interface (such as the guard); while the DVS can only be transmitted through the network to other computers or monitoring platforms, his advantage is the same management, front-end personnel Can't operate.
