Application analysis of network video server and matrix system

With the development of network technology and video compression technology, there are more and more methods based on network video to realize the construction of video surveillance project which is represented by the city security monitoring.

With the development of network technology and video compression technology, there are more and more methods based on network video to realize the construction of video surveillance project which is represented by the city security monitoring. However, in the implementation of network video monitoring system, there are two typical problems: firstly, how to use limited bandwidth to guarantee the transmission of important data, and the other is how to use the old and old analog matrix monitoring system rationally. In this situation, the use of the construction model to effectively solve these problems, is the majority of manufacturers and users are concerned about the focus.

As the industry's well-known overall solution provider, combined with a large number of practical project construction experience, heaven and earth Albert believes that the use of Network video surveillance system and matrix system combined with a multi-mode integrated video surveillance system can effectively solve the above two contradictions. Through the analysis and summary of the existing successful cases, we can combine the matrix system and the network video surveillance system to four kinds of typical modes: DVS mode, matrix switch mode, d+m mode and network matrix model, in the construction of the same project, these four modes can coexist together, And can be connected to the same platform for Management. To help readers understand the architecture of the system more deeply, refer to the following topology:

1, DVS Mode

This model can be understood as a conventional network video monitoring mode, front-end network video surveillance equipment, such as network video server (video input by analog cameras provided), network cameras, network balls, such as direct access monitoring network (Lan/wan). This model has the characteristics of simple construction, flexible distribution and convenient management. In the new monitoring point construction is particularly suitable for this way, at present in most of the city security, intelligent Community monitoring, campus monitoring and other projects in a large number of this way to new or expand the monitoring system.

At the same time because the world Albert in the Network video surveillance product development and design fully integrated into the matrix and DVR system of a number of advantage factors, such as: virtual matrix, concurrent multi-code flow, PPPoE, DDNS, RTSP, FTP, etc., in the practical application, Every network video surveillance equipment of the World Albert has played the role of the small integrated video surveillance host, whether it is a regular audio, video, alarm data or other special occasions of the detection data (temperature and humidity, current voltage, etc.), can access network video surveillance equipment, transmission through the network and then directly in the back-end call or analysis processing , making the design and construction of video surveillance more simple than ever before.
