Video Surveillance Fully Develops in the Age of HD Intelligentization

Since the early 1980s, Beijing Tiananmen Square installed the first batch of monitoring systems. China's security industry has experienced the process of introduction, imitation, digestion and absorption, and innovation. After 30 years of development, China's security enterprises have reached more than 20,000, employing about 1 million people; the industry's total output value reached more than 230 billion yuan. Among them, the output value of security products is about 100 billion yuan, the security engineering market and service market is about 130 billion yuan, and the entire industry realizes an added value of more than 80 billion yuan. Among them, security electronic products develop rapidly, with an average annual increase of about 25%.

In the composition of China's security industry, video surveillance accounts for a large proportion, accounting for 55%, entrance and exit control accounts for 15%, burglar alarm accounts for 12%, and other categories account for 18%. The manufacturers of video surveillance products in China are mainly concentrated in the Guangdong region, Jiangsu and Zhejiang regions, and Beijing and Tianjin regions, of which Guangdong Province accounts for about 70%, while Shenzhen concentrates on about 65% of manufacturers, and are the birthplace and manufacturing base of domestic video surveillance products. About 12% in Jiangsu and Zhejiang, about 10% in Beijing and Tianjin, and 8% in the rest. The market share of domestic brand video surveillance products has reached about 60%, but the high-end market is firmly occupied by international video surveillance brands. The products of domestic manufacturers have met the needs of the domestic low-end market, and there are a large number of OEM products to the international market. China has become a major producer of video surveillance products in the world.

Recalling the development of China's video surveillance industry, taking the development of video surveillance technology as a trajectory, the development of video surveillance industry can be divided into several periods:

Before 2005, it was the analog monitoring era;

2005--2008 is the age of digital surveillance;

From 2009 to now, it is the era of IP network monitoring, and it is moving toward the era of high-definition intelligence.

Before 2005, video surveillance was in the era of analog video surveillance. During this period, China's domestic video surveillance product manufacturers have relatively weak production R&D capabilities, and products mainly rely on imitation to participate in market competitions after low prices. The R&D of manufacturers is basically maintained at the research and development of some low-end technologies. The main funds are used to purchase machines. Core, lens assembly camera. The video surveillance products on the market are dominated by foreign brands. The number of foreign video surveillance products in China is very large.

During the simulation period, the main types of video surveillance products are basically the same as the types of video surveillance products currently available. Taking the front-end camera as an example, the color integrated machine, road-specific camera, day and night conversion camera, waterproof camera, infrared camera, high-speed ball, black and white/color gun, ball machine, hemisphere and other products are all available at the time, and the definition is usually 480 Line-based, and even then there was a network camera and network video server. Storage problems during this period were mainly solved by video equipment. Hard disk recorders are the most important storage products, including embedded hard disk recorders, PC hard disk recorders, digital hard disk recorders, matrix, DVR, some companies do video capture card. The monitor is mainly black and white/color CRT, and the product is relatively single.

At that time, the brands of video surveillance equipment were mostly foreign brands such as Sony, Dio Lika, Philips, JVC, Samsung, Panasonic, Honeywell, YAKO, Ante, Camstar, Hitachi, Uscarp, USA Boer, Daewoo Korea, Seiko Japan, Tamron, Computar, Fujinon, Bosch Germany, Pylego, Takasaki Japan and many more. Overall, there are few brands of video surveillance products in this period, and there are fewer product types and fewer domestic brands. Domestic enterprises are in the transition from agents to manufacturers. Foreign products and brands are basically dominating the world.

From 2005 to 2008, digital video surveillance technology has been greatly developed, and will soon develop from digital video surveillance to IP network video surveillance.

Domestic manufacturers have achieved rapid development during this period. Hangzhou Hikvision, Tianjin Ya’an, Tiandi Weiye, Jiajie Electronics, Dahua, Dali, Hanbang Gaoke, Advanced Video, Baoba Security, Shenzhen Wisdom Technology, Changzhou Mingjing, Shanghai Guanlin, Zhuo Yang Science and Technology, EVOC Intelligent, Weiwei Electronics, Hongtianzhi, Jingyang Technology, Shenzhen Wanjiaan, Tumin Technology, Skyworth Qunxin, Santian, Shenzhen Weishixun, Nanjing Guanzhilin, Red Apple, Shenzhen Shixinda, China Hui Yingke, Yu Xin Electronics, Shenzhen Yonghui, Risen Electronics, Shenzhen Shangjia, Shenzhen Baianxin, Sanli Video, Guangzhou Bao Qianli, Shenzhen Jiaxin Jie, Lize Smart, Shenzhen Witt, Shenzhen Zhimin, North China Industrial Control, Ringing Stone, Pokcon, Infinera, and a large number of companies have quickly grown into the backbone of the video surveillance industry, and have promoted the development of products and technologies in China's video surveillance industry toward the direction of IP and networking. New products and new technologies are constantly emerging. At the end of 2005, there was an Optical Fast Dome equipped with a TCP/IP module, a network dome and a fiber optic module. This signaled the beginning of the digital, IP, and network development direction of the video surveillance industry.

The rapid development of digital video surveillance technology and manufacturers in China from 2005 to 2008 benefited from the construction of a safe city in China and the construction of a technologically advanced police demonstration city initiated by the Ministry of Public Security in 2004. In 2004, the National Safe City and the construction of the science and technology strong police demonstrative city were promoted. The major cities in the country focused on the video surveillance command center and the large-scale safe city and the demonstration project of the science and technology strong police unified command, multi-level networking, distributed management, and more The demand for monitoring has promoted the development and application of digital video surveillance technology. In addition to the front-end digital camera, DVR, which is a digital video signal storage product mainly for domestic manufacturers, replaced the hard disk recorder. Digital video surveillance equipment began to replace analog products. During this period, the development of the market for video surveillance equipment was booming and flourishing.

China Public Security Magazine and the Chinese Institute of Public Security conducted a special survey on the domestic camera market in 2009. According to incomplete statistical analysis, by 2008, there were more than 600 small and medium enterprises capable of producing various kinds of cameras nationwide. In 2008, camera products produced 15 million units of finished products, with sales exceeding 12 billion yuan, of which domestic sales were about 5.6 million, and sales of Sony, Samsung, Panasonic and other foreign manufacturers accounted for about 39% of total sales. Domestic manufacturers account for about 61%. The production capacity of surveillance camera companies can reach an annual output of 20 million units.

Under the impetus of the 2008 Beijing Olympic Games, the concept of high-definition monitoring and intelligent analysis was highly respected in the video surveillance industry. High-definition video surveillance products with intelligent analysis capabilities began to be introduced. IP network cameras, megapixel cameras, high-definition DVRs, NVRs, and other products that represent new technological directions have become the focus of the industry. Based on the development of IP-based, networked video surveillance technology, video surveillance has accelerated from standard-definition surveillance to high-definition surveillance since 2009. The resolution of the video surveillance image is from the resolution of the 4CIF or D1 of the SD era, about 440,000 pixels, and the resolution of 540 TV lines. The resolution of the HD monitor has reached 1080i or 720p and the number of pixels has reached more than 1 million. Video surveillance has entered the era of high-definition.
