Thanks to the use of TCP/IP networks, network video surveillance can be remotely monitored and can be extended at low cost. The advantage of network monitoring compared with analog monitoring is here, so the application of network monitoring is more and more extensive, and its application technology is becoming more and more mature. From a specific point of view, we analyze the factors that network monitoring is superior to analog monitoring.
The advantages of network video surveillance over traditional analog surveillance
Compared with traditional video surveillance, network video surveillance facilitates the automation of compression, storage, analysis, display, and alarming of video information, thereby realizing unattended operation; remote monitoring is achieved through an Internet platform, even thousands of kilometers away. Can achieve the effect of being in person; using advanced software systems not only can complete a large number of data analysis in traditional video surveillance in a few minutes, improve the monitoring efficiency, but also can obtain more realistic, clear digital image quality and more convenient , Practical monitoring management and maintenance. In addition, the traditional monitoring system uses a centralized architecture. If you want to increase the number of cameras, you need to re-route the cables. You must pull all the video, audio, and control cables to the monitoring center. If you want to relocate the monitoring center, the project will be vast. The network video surveillance system adopts a distributed architecture. Each network camera and video server is distributed in different places in the unit. The surveillance video host can also be located anywhere in the unit and can be connected to the Internet. It is necessary to add cameras and transfer. Monitoring host can be performed at will, without any restrictions. In short, network video surveillance is a set of high-tech integrated products such as computers, networks, communications, and video codecs.
The factors that promote the rapid development of network video surveillance
1. Safe City promotes the rapid development of the application market of related industries. In addition to the traditional financial industry applications, the demand for video surveillance services is increasing day by day. At the same time, the requirements are different and each has its own priorities. With the gradual development of video surveillance, video surveillance is not an application of enterprise-level industry customers. Video surveillance applications will gradually develop towards the civilian use of video monitoring data for public services, such as traffic navigation, tourist attractions, people and attractions, etc. Many industries are promoting the application of network video surveillance.
2. The Internet of Things promotes the development of network video surveillance. Driven by the national Internet of Things strategy, governments and enterprises have deployed and planned the development strategy of the Internet of Things. As an important part of the Internet of Things, online video surveillance has greatly promoted the development of traditional video surveillance. .
The development of wireless network technologies such as 3, 3G and WIFI has expanded the application of video surveillance. The rapid development and increasing popularity of wireless technologies such as 3G and WIFI provide a good set of wireless video surveillance solutions for many inconvenient wiring environments such as on-board applications, temporary site monitoring, emergency command, and forest fire prevention. Compared with traditional video surveillance, mobile video surveillance has many advantages such as low cost, high flexibility, simple deployment, and suitable for any occasion, which has expanded the application of network video surveillance.
4, network video surveillance technology has gradually matured. Next-generation Internet (NGN) technology will have a huge impact on network monitoring. First, network bandwidth will change dramatically. Second, changes in network protocols. For example, IPv6 enables quality management and allows bandwidth for different content on demand. Distribution, this will produce a qualitative change in all kinds of video applications. Because NGN focuses on video applications.
5. The video surveillance service of telecom operators will help the growth of home users. The rise of personal and home monitoring markets and the application of digital video surveillance based on digital processing technology in the field of security have increased. In recent years, the intervention of China Mobile, China Telecom, and China Unicom has enabled network video surveillance to enter a broader field, namely carrier-level network video surveillance. For example, by integrating video surveillance with 3G, users can view the images of cameras installed at home in real time on their mobile phones, and remotely control the cameras via the buttons of their mobile phones. This has great appeal for home users. Industry insiders predict that mobile video surveillance will become the next major application of network monitoring.
6, PoE technology and its equipment. One of the big drawbacks of traditional monitoring is that the layout of power cords needs to be considered at any time, which also affects the development and development of the role of monitoring. The emergence of PoE technology and the release of related standards have successfully solved the power problem of network monitoring. In particular, the emergence of PoE switches has achieved “one-line dual-useâ€, reduced construction costs and wiring volume, and promoted the application and development of network monitoring. We would like to thank those companies that research and develop and manufacture PoE equipment. For example, Fontaine Tech, which has been continuously researching and innovating for 9 years, has introduced another PoE switch and other devices to make network monitoring more smooth and traditional monitoring. You can also enjoy the benefits of PoE.
Conclusion
There is no doubt that online video surveillance is attractive and the market prospects are very promising. However, this does not mean that there are no shortcomings, and there are no obstacles in the development process, such as the issue of bandwidth and transmission capacity. Although the current public network environment has been greatly improved; the type of network is also becoming more abundant in development, but with The existing public network environment is still difficult to support the huge flow of information; for example, the operating cost is still relatively high. These are the obstacles that need to be cleared up in the development of network monitoring. Only by solving these problems can network video surveillance be able to exert its maximum effectiveness and be truly popularized in the market.
