With the progress 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 family safety precautions strengthened unprecedentedly. Home network cameras, by virtue of their seamless compatibility with IP networks and the provision of remote real-time video processing capabilities and other network applications, have quickly become the fastest growing market with 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 digitalization of video surveillance is an inevitable trend of surveillance technology.
2. The video surveillance intelligent surveillance camera 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 users really need is only a small number of departments, or that only those events that need to be monitored are of low probability, how to obtain valuable information through massive data or how to visualize 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 becomes even more important to the user. In fact, existing monitoring systems are equipped with some primary forms of intelligent functions such as automatic displacement detection, day and night adaptive switching storage, and warning settings (such as suspicious figures, fingerprints, etc.). With the development of technology, the entire intelligent monitoring system will require the identification and accurate determination before the incident to provide 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 video cameras. With the development of Internet technology, IP-based video surveillance is more acceptable to people. Network cameras use compressed video information through the TCP/IP protocol and adopt streaming media technology to implement video multiplex transmission over the Internet, with authorized users. You can access the Internet at any time to achieve the command, scheduling, storage, and authorization control of the entire surveillance system. In view of IPv6's impact on the next-generation Internet network in terms of service quality, network performance, and security improvement, IPv6 will be the mainstream.
4. Wireless monitoring of video surveillance includes two aspects: First, monitoring the movement of the center. Usually, the monitored object or camera is often fixed. The user of the monitoring system (the monitoring center) can be dynamic. When the company leader is on a business trip and needs to understand the company's production status, the laptop can use the laptop to access the camera's IP access information anytime, anywhere. The second is the wirelessization of video surveillance networks. Following the development of wireless broadband networks, 3G-based wireless video applications have attracted much attention. When the monitoring points are scattered and separated from the monitoring center, or when the monitored objects are not fixed (such as taxis, armored cars, 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 an irreplaceable advantage.
With the development of computer, codec, and network transmission technology, video surveillance technology has experienced three phases of development. Currently, it is moving forward with digitalization, intelligence, IP, and network. 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.
