China video surveillance digital trend is clearly

In the composition of China's security industry, accounted for a large proportion of video surveillance, about 55%, 15% access control, burglar alarms accounted for 12%, 18% other categories. China manufacturer of video surveillance products are mainly concentrated in Guangdong, Jiangsu and Zhejiang, and Beijing-Tianjin region, which accounts for about 70% of Guangdong, and Shenzhen on the concentration of about 65% of the manufacturers, is the birthplace of video surveillance products and manufacturing base ; Jiangsu and Zhejiang provinces accounted for about 12%, about 10% in Beijing and Tianjin, and the remaining regions together accounted for about 8%. Video surveillance of domestic brands to reach 60 percent market share, but the high-end video surveillance market is an international brand firmly occupy. The products of domestic manufacturers to meet the domestic demand for low-end market, there are a large number of OEM products to the international market, China has become the world's largest producer of video surveillance products.

     Recalling China's video surveillance industry, to video surveillance technology for the track, the video surveillance industry can be divided into several periods:

     Prior to 2005 times for the analog control;

     2005 - 2008 era of the digital control;

     Since 2009, the era for IP network monitoring, and toward high-definition intelligent times.

     Before 2005, the analog video surveillance video surveillance in a long time. During this period, China's domestic production of video surveillance products manufacturer R & D capability is relatively weak, mainly by imitation products compete in the market after a low-cost, basic maintenance, R & D R & D in some low-end technology, the main funding for the purchase of machine core, the camera lens assembly. Video surveillance products on the market to foreign brands.

In the 2008 Beijing Olympic Games, driven, high-definition monitor, the concept of intelligent analysis and highly respected in the video surveillance industry. HD, with intelligent analysis of video surveillance products began to launch. IP network cameras, camera megapixels, HD DVR, NVR and so represents a new direction of technology products become the focus of the industry. IP-based, network-based video surveillance technology, beginning in 2009, video surveillance monitoring from SD to HD monitor the pace of development accelerated. The resolution of video surveillance images from SD age 4CIF or D1 resolution, about 44 million pixels, resolution 540 TV lines, the development of high-definition resolutions up to 1080i or monitor age 720p, up more than one million pixels. China wireless surveillance systems has entered the HD era.

Network video surveillance revolutionary impact

Network monitoring and gradually into the spotlight. The development of  wholesale wireless surveillance equipment from analog to digital, from wired to wireless, it is undergoing a technological revolution after another, while the market has also undergone corresponding changes. 2010 Security market value of nearly 230 billion yuan, accounting for nearly 30% of the peaceful city, the market value of more than 600 million; in peace building in the city, accounting for 20% of network surveillance cameras, has formed a large-scale market. Prompted the city to promote the safe construction of network monitoring applications to enter into a new period of change.

As we all know, building wiring system is very complex and complicated matter, the birth of network surveillance cameras to solve the "no special cable can not monitored," the embarrassment; technological means of intervention also makes analog control is gradually being replaced by digital surveillance. Green cities monitor as the image screen higher, so the demand for high-definition network camera, so safe city construction makes network monitoring cameras have been an unprecedented opportunity for rapid development. I interviewed that, with intelligent video analysis technology gradually improved, safe urban systems, intelligent analysis of urban systems in the safe application will shine, from digital to the network, and then develop into intelligent, competitive intelligence will affect the market.

The emergence of 3G wireless network to solve the network monitoring wiring problem. But faced with the dual pressures of high costs and stability, 3G technology does not mean that wireless video surveillance market in a year or two widely used. The current 3G wireless system set up by several operators, but the safe mode of urban systems around the building but not the same. Some areas are relying on public network operators to build, set up the video in some areas on their own private network. In either mode, networking, 3G wireless networks are not technically docking problem. But only technically simple docking is not enough, the 3G wireless monitoring system with the combination of traditional fixed-line monitoring system, the business processes to achieve interoperability in order to be called fusion. So in terms of technology maturity, the improvement of the network, changes in consumer attitudes, business model changes, etc., the maturity of the market will take some time.

Peace building in the city to back-end storage systems for the development of the core DVR, embedded DVR early central management server, add the video relay server in the node, but with the increasing urban monitoring data and network services, convenience, back-end storage technology is undergoing subtle changes. NVR mass distributed intelligent storage network to meet the needs, NVR-definition IP cameras is also the most cost-effective solution that can reduce deployment costs and promote the popularity of high-definition monitor;on the other hand, NVR design flexibility and integration bring low-cost characteristics, can greatly enhance the ease of cheap wireless surveillance system, application and popularization of the market also has a significant role in promoting. While NVR on the market has not been widely used, but leveraging the construction of the Safe City to develop the core DVR NVR is to promote road.
