Currently langchi Yan invasive product application area covers a very wide range, related to financial, public security, transport, industry, agriculture, services, and many other fields, have been in several large famous works, particularly in recent years, accidents, high risk sectors such as: coal production, steel production, petroleum industry, have adopted langchi Hsin Chuang's security products.

As parts of the city monitoring project needs, domestic network application stability and rapid development of high-bandwidth, these have become a network monitoring to the market of external factors.

And video server similar products is the video encoder, but very often we put video server and equate video encoder, but real video server and encoder's biggest difference is the video server is more attention to video encoding rate and low bandwidth transmission, really excellent video algorithm and product combination. While the video encoder key concepts lot still at commonly used high-bandwidth transmission of images.

Because traditional DVR as well as its basis, extend the functionality of the network DVR product, so that more users can access it, it is this concept of product development, whether it be with network features of DVR products or traditional sense of the DVR, its main function is to store, which also determines his market positioning is a small area of the network environment, the control point is also limited.

This hinders the development of a DVR, and video server is not affected by this limitation.

DVR and traditional video cassette recorder (VCR) contrast does have many advantages, such as: no need to replace the tape, coherent image guarantee and fast search capabilities.

But you still not get out of those complex analog video cables, which can greatly reduce the image quality, and the whole system down prices but also quite expensive.

Video server more unique:

Multiple channel, network transmission, image and playback capabilities simple integrated network.

Remote control, video server, network technology, you can implement as long as we can online place for browsing pictures, all information, regardless of the video is live or recorded, and can be anywhere in the world of security.

Adopt the necessary decoder you can do not need computer equipment directly to the video wall, and other ways to browse, great savings in the cost of the remote control.

Video server scalability is very good, can be from one to thousands of capacity.

You can unlimited provides real-time user-selectable output frame rate.

Video server has a more cost-effective based structure of most devices now have access to the twisted pair, this is a video server provides very good preparation, you only need to access network cable can easily handle everything.

Because all the data, video, sounds, and other are transmitted via a network cable and management.

More low-cost of the system.

Video server is present all the cameras installed in the most economical choice. It is based on open standard Web protocols, making it the advantage of contrast to the DVR will be prominent.

Video services can be

On the following aspects for further expansion.

· Mobile

Relative to conventional analog monitoring and network monitoring, mobile video surveillance is an important development in the future.

Normally, when monitoring point and central control center location away from the more distant and more dispersed, traditional way of network wiring cost is very high, and in the event of obstruction or river mountain range wait for target monitoring point is not fixed or moving objects (such as carrying vehicle, ship, etc), the cable network is helpless. At this point, the mobile network unparalleled advantages it embodies. The mobile digital video surveillance system, you can use a variety of wireless transmission means such as GSM, CDMA, BWA, they played mainly in the network connections monitoring points and monitoring center data transmission link. But the big operators are actively planning and preparing for the operation of its mobile network, the future 3 g more to digital surveillance system provides higher bandwidth and speed so that the mobile digital monitoring to the mountains, rivers, bridges, roads, and other complex terrain limitations, faster construction cycle, to meet the demand for flexible application, etc., to become the future video surveillance is an important direction.

· Integration with CNGI provide IPv6-based video surveillance

Officially launched in China in 2003 by the national development and Reform Commission, eight ministries launched national special: the next generation Internet demonstration project (CNGI demonstration network).

CNGI demonstration project aims in 2003-2005 period, completion of construction and CNGI backbone of domestic/international Internet Center and covered 20 cities 39 core node construction. This project involves six of the eight ministries, national network operators, more than 100 colleges and universities and research institutions, dozens of equipment manufacturers, workload, broad, the number of participants, in China's telecommunications network in the history of science and technology project is the first time, on our next generation of Internet technology and industry has a profound impact.
