What are the characteristics of Zhengzhou video server? The configuration scheme of is the video monitoring equipment developed in recent years. With the development of network technology and the popularization of broadband network, network video monitoring will gradually erode the market share of traditional video monitoring equipment. Video server? Although DVR also has network monitoring function, the main network monitoring equipment is video server, which can convert analog video, audio or voice signals into digital signals and transmit them through IP network. At the same time, the network video server also has a variety of auxiliary functions such as alarm, PTZ control, etc. The video server generally includes audio and video acquisition part, CPU part, data encoding part, network part and alarm control part. Since the data output from the camera to the DVS is analog signal and the signal transmitted by the network is digital signal, it is necessary to perform a/D conversion on video and audio acquisition to make them digital signals. However, the amount of digital signal data after a/D conversion is quite large. At present, the domestic computer network bandwidth is limited, and it is unable to transmit a large number of data streams. Therefore, they need to be encoded and compressed to ensure the clarity of the image as much as possible and compress the data into small flow data that can be transmitted on the Internet. The network part needs to support DHCP, DDNS, UPnP, NFS and other network protocols.

Some basic features of the current popular servers with a frequency of [100 Hong Kong dollar servers] are as follows.

1。 This model is very small. Generally, 1-4 analog video inputs, different from hard disk recorders, can easily input more than 10 channels of video, and do not carry a hard disk. The storage device is placed in the monitoring center, which is more conducive to the storage and protection of image data and saves a lot of space.

2。 Simple At present, video data is transmitted to the monitoring center through the computer communication network, developing rapidly and with high efficiency. Only one low-cost Category 5 network cable is required. If the video server has a WiFi module, you can use WLAN to save 5 kinds of network cables.

3。 Strong central control. An industrial standard server and a set of control management application software can run the entire monitoring system. The user only needs to open the client program on the computer connected to the Internet, input the IP address of the corresponding video server, and can carry out comprehensive remote monitoring. Any authorized customer can directly access any camera or monitor images through the server center

4。 Easy to upgrade and fully scalable. It is convenient to add more cameras. In the future, it is also convenient to upgrade the server center to faster processors, larger disk drives and larger bandwidth.
