HD, intelligent video surveillance has become a new industry growth point

At the Shanghai World Expo last year, a group of high-end high-definition surveillance application projects played a substantial role in the development of the Chinese high-definition surveillance market. In 2010, it was known as the first year of high-definition video surveillance in China. The R&D, manufacturing and application of high-definition and intelligent monitoring products have become the development direction and new growth point of the industry.

High-definition video surveillance is an inevitable trend in the development of digital information era. With the promotion and popularization of broadband networks, the area and scope of surveillance will be expanded and penetrated into every corner. Zheng Xiaolong, TI's general DSP business development manager, pointed out that the increase of network bandwidth and the guarantee of transmission quality have become the basis of high-definition. However, taking into account the utilization of network bandwidth, there is still a need for compromise and compromise in the pursuit of smooth video streaming and high-quality picture, because HD can use 720p as an entry-level, 1080p can become mainstream HD, but there are 60 frames per second and 30 frames of two levels, the demand for broadcasting and entertainment is naturally the former, and monitoring and communication are usually considered the latter, this not only considers the support of network bandwidth, but also consider the support of display devices.

Shen Hongren, marketing manager of Taiwan branch of Fujitsu Semiconductor Co., Ltd. in Hong Kong, believes that in the development of high-definition, the current market demand starts with 720p 30, and the advanced specification is 720p 60 or 1080p 30. Some applications, such as license plate recognition (LPR), even require 1080p 60 or higher specifications. This requires the gradual advancement of sensor technology to high-order CMOS (1.3M, 2M, 5M, etc.), while CMOS has also caught up with CCD in terms of high dynamic (HDR) and low lux. In addition, high-level image processor (ISP), high-order coding technology (H.264) and high-resolution lens (HD Lens) are also important technological development directions.

Intelligence must be an important value-added point for digital video surveillance. Zheng Xiaolong said: This refers to the practical value of the system, not just the cost. The meaning of monitoring should be that it can realize on-site monitoring and real-time control, but it is often difficult to achieve complete control by relying on human power to view the screen. Only by combining intelligence can we fully control everything. Of course, the current cost of intelligent monitoring equipment is still slightly higher, which inevitably brings high system costs. However, with the increase in the integration of digital media processor platforms and the continuous enrichment of intelligent monitoring algorithm software, the popularity of relevant intelligent applications will increase. Just around the corner. The demand for digital video surveillance for the Internet of Things is also very strong. In particular, the realization of video sensing is closely related to the application of intelligent video analytics.

In fact, in addition to traditional pan-tilt control camera steering/zoom functions, the current market demands more and more applications for smart audio and video analysis (front-end and back-end). Shen Hongren pointed out that this requires a corresponding development in terms of technology, such as the development of smart video and audio analysis software. He said that most of the smart audio and video analysis is implemented on the back end, such as the CMS or offline software analysis, but some smart audio and video analysis functions are gradually built into the head-end (camera) for important event monitoring and data analysis. .

According to Zhang Yundong, CTO of China Star Microelectronics, high-definition products can provide more details of video and bring completely different user experiences. Many security users often do not want to change their original picture quality once they use HD products with vivid colors and clear details. Low analog products. Monitoring the trend of intelligent products can help users save a lot of time. In the past, a security guard could only monitor a dozen monitors at the same time and reach the limit. With intelligent analysis products, hundreds of cameras can be filtered by machine intelligence. Security personnel can monitor the results of intelligent analysis and use intelligence. Technology can increase security work efficiency by many times. Moreover, with the development of the Internet of Things technology in the field of video surveillance, video capture, transmission, and application are more intelligent, and intelligent analysis technologies will lay a solid foundation for the Internet of Things.

Zhang Yundong introduced that Zhongxing Electronics, a subsidiary of China Star Microelectronics Group, saw the opportunity of high-definition and intelligence early. At the same time, it has a research and development team that is the foundation for chip R&D and large-scale operation platforms. China Star Electronics has long positioned itself as a core provider of high-definition and intelligent security equipment. Currently, Zhongxing Electronics has formed a complete product series: front-end products such as 1080p-based high-definition network cameras, back-end product lines supporting high-definition and standard-definition hybrid NVRs, and support for high-capacity carrier-grade platform product series, and both distributions Intelligent analysis of hardware products, there is a centralized intelligent analysis and processing platform.

It is understood that the application of Vimicro's products involves more than a dozen fields such as the government's public security, finance, military, parks, education, energy mines, environmental protection, and intelligent transportation, and it has various application solutions such as safe cities, intelligent transportation, and intelligent buildings. Typical applications include operators in more than ten provinces such as Guangdong, Jiangsu, Fujian and Gansu, as well as government large-scale operation platforms for public security. They are also used in major events such as the Shanghai World Expo and the 60th anniversary of the National Day.

During the 2010 Shanghai World Expo, Hikvision participated in the construction of the video surveillance system in the entire Pudong New Area. Yang Peiwen, director of international marketing of Hikvision Digital Technology Co., Ltd., introduced that all Surveillance cameras in Pudong New Area were using high-definition equipment in about 10,000 surveillance sites. This is a classic example of a typical early large-scale use of HD surveillance. Yang Peiwen revealed that Hikvision also completed the highway traffic monitoring system in Fujian Province. It integrates with the existing toll system and the speeding system. "With the further development of the company, the construction of the software part is also gradually followed by Hikvision." Hikvision's largest chip supplier is TI.
