How video servers work and how they are applied

The video server has made great progress in the development of technology over the years, and the application of video server is more and more extensive, which is the result of technology. Then the following mainly introduces the application of the video server:

First, I will introduce you to a video server application case: The first video server I came across was 5 years ago, when it was a pure analog architecture. The security system dominates the world. This case is a Taiwan-funded company that does ornamental fish farming and needs to renovate its existing video surveillance system: the company has two breeding bases in Taiwan and Guangdong, each with its own independent video surveillance system. In consideration of confidentiality, the customer is worried that DVR recording in the original system may reveal important information such as his farming technology and sales volume. Therefore, it is required to remove the DVR in the original system, and the modified system has a network function, so that it can be opened at any time in different places. The web page shows customers their farms. After research, they chose a video server to transform the customer's original system and removed the front-end DVR equipment. Customer privacy is protected through network access control. At this stage, the video server application only stays in the simple video forwarding network function, the image quality is general, the function is single, and the software support is also lacking.

In recent years, with the further expansion of network technology and network applications, it has also brought opportunities for the development of video server professional equipment. Well-known enterprises in various industries have organized research and development forces to carry out technical research and launched a large number of new-generation video server products with characteristics. The current video server technology has been relatively mature, forming a relatively standard technical feature, which is expressed as:

Simultaneous transmission of real-time images, synchronous transmission of detection data and status information, D1@25fps image quality, with RS422 /RS485 serial communication interface can be connected to various peripherals such as cloud mirror, multi-protocol support, two-way audio real-time transmission, video frame rate automatically adjusted according to bandwidth, automatic connection after network interruption, perfect alarm function, USB backup interface, lower Power consumption, higher stability, and more.

Nowadays, video servers have gained more and more applications in actual projects. For example, a Taiwan-funded enterprise has established production bases in three cities in the mainland. Each base has several independent product lines, which are relatively independent in management. Originally, the bases used an analog video surveillance system, and the system was difficult to manage centrally. After field inspection and customer demand analysis, it is recommended that customers use video servers to transform the original monitoring system. Each base has relatively independent management of each product line through rights management. For sensitive areas involving patented technology, hardware access control is adopted. It is forbidden for external network customers to access. The three bases all realize network connection through the original VPN private line of the enterprise. The central control center centrally manages and adds the JDR electronic map management module. The system has performed well overall so far, and the system has shown good compatibility in the later expansion of the customer and has been well received by customers.
