With the rapid development of society and economy, the surveillance system in the security industry has been widely popularized and developed. In recent years, with the rise of the real estate industry and the large-scale construction of safe cities, the entire industry has been developing rapidly. The growth rate of more than 20% is far ahead of the global security market. Security technology has also evolved from the culmination of the most primitive pure analog systems to the era of front-end analog back-end digitization. In 2011, as the first year of high-definition, the combination of intelligent applications is the trend, and the demand is innovation.
Market demand, high-definition network high-speed ball shine is well-known, the reason why high-definition network high-speed ball gradually shine in the market, precisely because the market put forward the demand for high-definition monitoring. Moreover, compared to the traditional analog high-speed ball, the HD network high-speed ball has a high-definition picture, a wider coverage, easy-to-expand performance, and intelligent analysis functions, and can meet the high demands of users in the market.
In terms of resolution, the definition of HD network high-speed ball has achieved a qualitative leap, providing users with more picture pixels and showing more abundant picture details. Liang Ge, Product Manager of Tianjin Yaan Technology Electronics Co., Ltd., said that compared with the analog and standard speed domes, the resolution of the megapixel high-speed ball is generally more than 720p, which avoids the original monitoring picture is not very clear, even In some places, there is a phenomenon where the fuzzy resolution is not clear.
In addition, it is worth noting that the high-definition network high-speed ball can also provide users with timely and effective monitoring services through the addition of intelligent analysis functions. It is more convenient for positioning and tracking in outdoor complex environments. In the high-definition network high-speed ball more typical intelligent analysis technology includes motion detection, face recognition and so on. "For example, based on behavioral analysis technology, intelligent analysis functions such as personnel focus, traffic detection, cross-line detection, and alarm real-time uploading can be realized," said Hu Ping, product manager of Hikvision (002415, stocks). At the same time, on the basis of high-definition image quality, facial analysis functions can be combined with the application of face data in the database. If some of the key locations are found to be robbery incidents, they can be traced more quickly and accurately. Or, it analyzes the flow of customers and goods in shopping malls and supermarkets, and provides managers with analysis of the flow of people and businesses. Chen Yong, product manager of security product monitoring and control for product solutions at Panasonic Corporation (China) Co., Ltd. mentioned.
The combination of high-definition, intelligent, application trends will not be difficult With the economic development, security and other video application system technology has also been continuously upgraded and progressed, many large-scale, high-end video surveillance projects have selected high-definition network cameras, intelligent high-definition network camera technology It is a highly technically intensive technology application.
With the development of video analytics technology, products are gradually integrated, and there are two development trends: intelligent front-end and smart back-end. Smart front-end is the main trend. From the perspective of applications, intelligent analysis is not only used for security monitoring, but also can be used for enterprise or industry management. For example, license plate recognition, and face recognition, can be used for bayonet, access control, statistics of specific people or cars entering and leaving a specific area. The queuing length estimation of retail or business processing, the estimation of the density of personnel in the service hall, and the statistics of customer density in various areas such as shopping malls or warehouses, and the statistics of customer density in various regions can all allow managers to make timely management adjustments. Video analysis needs to be developed specifically for specific applications or even on specific occasions based on conventional intelligent analysis. However, these application-specific developments are fundamentally different from general-purpose intelligent analysis methods in terms of algorithm principles.
For example, in the designated position, monitoring whether there is a vehicle passing, equivalent to the function of the sense coil, also called "virtual coil", can not be used to intelligently analyze the mid-span function, and its detection rate is not reachable Coil requirements. The “virtual coil†technology developed by the Shenzhen Graduate School of Peking University is the feature-based detection technology adopted. Through field tests conducted in Anhui Tongling and other places, the technical requirements expected by Party A were met, and a number of patented technologies were born. , even including some basic algorithms for image processing; another example is the vehicle-based pedestrian detection algorithm developed by the Shenzhen Graduate School of Peking University in collaboration with the Hong Kong Productivity Council, which uses the combination of HOG and HAAR features in a fast moving and changing context. Completed the accurate detection and early warning of pedestrians and successfully carried out on-board experiments, which was highly recognized by the Hong Kong Innovation Agency.
High-definition network cameras, as the front end of the intelligent analysis platform, combine the application of the two, making intelligent analysis more widely used and popularized, and at the same time further promoting the development of high-definition network cameras, becoming an important aspect of network cameras relative to analog cameras. Advantage.
Is the conclusion that innovation has changed the demand or that demand has won the market? In fact, some companies have already seen the trend of digital security as early as 2006, and are committed to the research and development of high-definition network cameras, and gradually guide the development trend of the industry's high-definition intelligent network cameras. At this stage, with the application of intelligent technology, multi-network integration, and new technologies such as Internet of Things, the monitoring system will become more and more mature.
