With the improvement of people's living standards and the popularity of the Internet, security protection has become more and more popular. Especially in recent years, the development of information technology and the improvement of people's living environment have made people's awareness of home security prevention strengthened unprecedentedly. Home network video surveillance, with the seamless compatibility of technology and IP networks, as well as the provision of remote real-time video processing capabilities and other network applications, quickly emerged as the fastest-growing market at a 40% annual growth rate. Its market demand is limitless.
At present, the mainstream development trend of network video surveillance mainly includes the following aspects:
1. Video Surveillance The development of digital video surveillance experienced three stages: analog video surveillance, semi-digital surveillance, and digital surveillance. For video surveillance, digital storage brings a revolutionary change. Digitization is a feature of the 21st century. The digitization of video surveillance is an inevitable trend of surveillance technology.
2. Intelligent video surveillance is a relatively advanced level of video surveillance technology development. Because the amount of data for video surveillance is very large, and the information that the user really needs is only a small part, or that there are only some events that really need to be monitored with a low probability of occurrence, how to obtain valuable information through massive data or how to visualize it Interpretation becomes automatic machine interpretation is a new direction for the development of video surveillance technology. The ability to turn video surveillance from static, post-forensic to dynamic, real-time prevention and alerting is even more important to the user. In fact, existing monitoring systems are equipped with some low-level intelligent functions such as automatic motion detection, adaptive day-and-night switching, alert settings (such as suspicious figures, fingerprints, etc.). With the development of technology, the all-intelligent monitoring system will require prioritization to identify and make correct judgments, providing people with the most effective and timely rapid response measures.
3. Video surveillance IP video networks, IPTV, etc. are all important applications for the rapid development of networks. With the development of Internet technology, video surveillance based on IP is more acceptable to people. The network video camera uses compressed video information through TCP/IP protocol and adopts streaming media technology to implement video multiplexing transmission on the Internet. Users can access the Internet at any time to achieve the command, scheduling, storage, and authorization control of the entire surveillance system. In view of the impact of IPv6 on improving quality of service, network performance, and security to increase the impact of IPv6 on next-generation Internet networks, IP-based video surveillance will become mainstream.
4. Wireless monitoring of video surveillance includes two aspects: First, the movement of the monitoring center. Usually, the monitored object or camera is often fixed. As a user of the monitoring system (monitoring center) can be dynamic, when the company leaders are on a business trip and need to understand the company's production situation, they can use a laptop to access the camera's IP anytime, anywhere to obtain information. The second is the wirelessization of video surveillance networks. With the development of wireless broadband networks, 3G-based wireless video applications have attracted much attention. When the monitoring points are scattered and distant from the monitoring center, or when the monitored objects are not fixed (such as taxis, armored vehicles, etc.), video surveillance using traditional wired networks is often costly and difficult to implement, and based on multiple wireless transmissions. Means of mobile video surveillance have irreplaceable advantages.
With the development of computer, codec, and network transmission technology, video surveillance technology has undergone three phases of rapid development, and is currently moving towards digital, intelligent, IP, and network development. At the same time, video surveillance is combined with other technologies, resulting in many new applications, which helps meet the needs of different home video surveillance users.
