At present, China’s security market on the high-definition network monitoring market, basically still in the initial stage, all kinds of chips, products, system integrators, system platform business in the high-definition network monitoring market sales are still testing the water stage, high-definition network monitoring Of the technology, systems are still in continuous improvement period. Hidden wifi camera seems to have become a pair of high-definition combination of powerful combination in the world’s security market and emerge debut.
At present, China’s security market on the high-definition network monitoring market, basically still in the initial stage, all kinds of chips, products, system integrators, system platform business in the high-definition network monitoring market sales are still testing the water stage, high-definition network monitoring Of the technology, systems are still in continuous improvement period. Spy hidden camera seems to have become a pair of high-definition combination of powerful combination in the world’s security market and emerge debut. As the front-end equipment for high-definition video surveillance, HD miniature wireless hidden camera is the source of video surveillance, HD video encoding and IP encapsulation, IP network to carry high-definition images, enabling high-definition surveillance, video and other monitoring functions. From the triple-play next-generation Internet (NGN) technology, radio and television, telecommunications, the Internet, and mobile broadband and other wireless networks will be integrated into the next generation of the Internet. To-packet switching for the characteristics of the IP network, replacing the original line to the exclusive transmission network. It will be more comprehensive coverage, and omnipresent. Wired, will be fiber to the home (light into the copper back) -based, wireless, WIFI +4 G automatic switch-based. Wired and wireless broadband for video transmission provides a great convenience, which is the basis of video surveillance network. Video surveillance as a video transmission as the core system, will also be integrated into this large network system, information island will be eliminated. This is because, from the wisdom of the Earth (city) point of view, all the information needs to be interconnected in order to make intelligent decisions, video surveillance system, not only the needs of public security, emergency command needs, government leaders need, , Fire, environmental protection, water, etc. are needed. Of course, access rights and security needs to be protected, but this is not an excuse for the existence of information silos. Now, the country is vigorously promote the application of Internet of things technology and development, the basic idea is “things connected, perception of China”, that is, “a more thorough and thorough perception, more comprehensive interoperability, more intelligent decision-making” . Video and its direct access to the Internet, high-definition mini wireless camera, will be the first source of human information, will be in the Internet of Things, the next generation of Internet applications play a more ambitious role.

Technical Analysis of Intelligent HD hidden spy camera
Intelligent high-definition miniature wireless camera technology is a highly technology-intensive technology, high-definition miniature wireless camera development from the clarity and transmission speed and application of many aspects of the integrated view, involving a number of core technologies and intellectual property, Mastering these core technologies requires enterprises to invest a lot of manpower, material resources, time and money, need to accumulate and accumulate, so it also improves the industry to enter and competition threshold.
Analysis of Video Intelligent Analysis Technology
High-definition miniature wireless camera’s biggest advantage is that you can achieve a powerful video intelligent analysis technology. As an important medium for the realization of intelligent functions in HD monitoring system, video analysis plays an important role in the application of HD monitoring system. HD mini spy camera provide enough pixels to provide more details and features, and make the classification of objects even more Identification becomes possible. In capturing images of a high-definition miniature wireless camera for monitoring purposes (non-professional capture), such as face, license plate, behavior, and the like can be identified.
The existing intelligent analysis mainly includes the following links:
Target detection: The current target detection technology is based on Gaussian (or multi-Gaussian model) background estimation and background subtraction method, this method in the light of intense environment (such as the bustling streets, neon intersection) and other occasions , It will fail, then the use of feature-based detection method is possible to work. High-definition miniature wireless cameras can provide sufficient pixel and byte characteristics, can resist the interference caused by light changes. The current video analysis technology, compared with the traditional motion detection technology, the main progress is to filter some of the rules of movement, such as tree shaking, water wave movement, fountains, etc., and slow light changes and so on.
Target tracking: The goal of continuous video detection, the establishment of moving target association, in order to achieve the goal of tracking, and identification (the establishment of the target ID) in order to conduct an effective behavior analysis. In the tracking process of the target, the method of prediction, such as linear prediction, Kalman filtering, ion filtering and Mean-Shift, can be used to establish good tracking and solve the problems of target overlap and occlusion. High pixel characteristics, the tracking effect is also a substantial increase
Target behavior analysis: Based on the establishment of the target tracking, the target can be an effective behavior analysis, such as cross-line, cross, enter the region, exit the region, wandering in the region, retrograde, counting (traffic statistics) , Remnants, and the like.
