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.
