In recent years, China’s video surveillance market has been strongly stimulated and driven by factors such as the “Safe City” project, Olympic security projects, airports, subways, scenic spots, and the acceleration of demand for security projects in various regions and industries. This has achieved rapid development and overall market size. Rapid expansion. China's video surveillance market has also experienced three major stages of analog surveillance, digital surveillance and network monitoring. According to the market research conducted by a certain department, in the past few years, as the first generation of video surveillance technology, analog surveillance has a large degree of decline in market share due to its limitations in image quality and monitoring.

The digital monitoring of the second-generation monitoring technology has greatly improved image quality, storage time, and reliability, providing users with cost-effective monitoring solutions. At present, digital surveillance has firmly become the video surveillance solution that dominates the overall video surveillance market, and is maturely deployed in financial, commercial and other industries.

As the third-generation monitoring technology, network video surveillance, along with the rapid advancement of network technology and video technology, has promoted the rapid development of large-scale projects such as the Safe City, Beijing Olympics, Shanghai World Expo and Guangzhou Asian Games, and has achieved great development in the market. Hot. It is understood that by the end of 2008, China's online video surveillance market has reached 520 million. It can be seen that network video surveillance products have generally been recognized by consumers.

In recent years, network video surveillance has become the main thrust of the market, especially the large-scale deployment of carrier-grade network video surveillance systems, which has promoted the maturity of network video surveillance models. At present, the entire security industry has entered the era of network monitoring. Whether it is video surveillance, alarm access, access control, or storage devices that serve as the basic support system for security monitoring, it has begun to present a networked development trend with IP as the main feature. The security industry has also begun to enter the IT development process represented by IP technology and realize the intelligent application of network monitoring systems. Fast installation and wide application of network cameras are becoming more and more popular and become the focus of the current security market.

Network Video Surveillance is another “industrial revolution” in the video surveillance industry following DVR. It integrates a new generation of camera technology and network technology. It has obvious advantages in terms of product application and technology.

From the perspective of application, it can not only be based on computer local area network for regional monitoring, such as residential quarters, villas, office buildings, banks, shopping malls, supermarkets, chain stores, factories and other traditional monitoring; but also can be used for remote remote monitoring through the Internet and Online display, such as remote children and elderly care, unattended communications room, garage monitoring and so on.

From the technical point of view, it adopts the most advanced camera technology and network technology, and the built-in modular configuration enables true plug-and-play, freeing users from complicated network configuration and wiring; built-in infrared detection technology can It can detect abnormal conditions in time; built-in I/O ports and communication facilitate the expansion of external peripheral devices, rich function expansion, improved the use efficiency of network cameras, and achieve remote, full-time, multi-mode (mobile phone, computer, public security linkage ) And other kinds of viewing methods.

With the popularization of the Internet, access to broadband, improvement of people’s living standards, gradual transformation of consumer awareness, and continuous development and improvement of network video surveillance technology, online video surveillance has come.
