Four basic features and advantages mortem of network video server

Network video Server (dvs,digital), also known as digital Video encoder, is a kind of compression, processing audio and video data professional network transmission equipment, audio and video compression codec chip, input and output channels, network interface, audio and video interface, RS485 serial interface control, Protocol interface control, system software management, mainly provide video compression or decompression function, the completion of image data or recovery, the current more popular based on MPEG-4 or H.264 image data compression through the Internet network transmission data and audio data processing.

Four basic features of network video server

With the development of http://www.aliyun.com/zixun/aggregation/12311.html > Network Technology and the popularization of broadband network video surveillance will gradually embezzle the traditional video surveillance equipment market share, Here's a look at the four basic features of a video server:

1. Small model. Generally, 1-4-channel analog video input, not like a hard disk recorder as often as more than 10-way video input, and will not randomly carry hard disk, storage devices placed in the monitoring center is more conducive to image data storage and protection, which saves a lot of space location.

2, simple. Through the current development of rapid, cost-effective computer communications network to the video data transmission to the monitoring center, only a Low-cost 5 network cable, if the video server has WiFi module, the use of wireless LAN mode, then even 5 types of network cables are saved.

3. Powerful central control. An industrial standard server and a set of control management application software can run the entire monitoring system, users just open a computer connected to the client program, in which the corresponding video server IP address can be fully remote monitoring. Any authorized client can access any camera directly, or it can access the monitored image through a central server.

4, easy to upgrade and full scalability. Can easily add more cameras, the central server will be able to easily upgrade to faster processors, larger disk drives, and greater bandwidth.

1. Convenience of installation and maintenance

It may be said that "the current network bandwidth is not enough, optical transceiver and fiber for remote transmission, video image quality and transmission speed than network transmission better." However, the installation of optical fiber expensive cost and complex wiring works, so that many customers and contractors difficult to bear. Because of the popularization of computer network, there can be built network monitoring system, installation cost is greatly reduced.

2, easy to use, want to see

Network monitoring is not limited by the time and place, and monitoring on demand, can selectively watch the image of the designated location, and do not need to see the image is not transmitted, saving the network bandwidth resources.

3, with more intelligence

can be timely and automatically extracted from the video stream a large amount of information, which can be transmitted, saved, retrieved, offsite storage, multi-computer backup storage; The camera can be programmed to transmit images only when a particular event occurs.

4, the image attenuation is small, the quality is guaranteed

The use of advanced digital compression technology, digital signals in the transmission of small attenuation, quality assurance. and analog video signal after a long distance transmission, the signal will decay, need to configure video amplifier compensation.

5. Stable and reliable

The network video server uses the embedded operating system, the hardware uses the High-performance chip, the work is stable.

6, can realize wireless network transmission

Using Network video server to convert video signal into digital signal, in the case of inconvenient traffic and difficult wiring, we can set up wireless local area network, send digital video signal to monitoring center, and then release it to the remote Management department by monitoring Center. The advantage of WLAN is the convenience of networking, short cycle, low investment and flexible structure.
