It is understood that the construction and application of high-definition surveillance systems have become an important part of the wave of construction of video surveillance systems throughout the country. Especially in first-tier cities, HD has gradually become mainstream.
No matter how hot the HD is, the market application is the best way to tell whether it is mature. It is understood that the Xiamen municipal government plans to invest more than 6 million yuan to build a batch of high-definition video surveillance systems. Moreover, there is a lot of similar information across the country.
Some people in the industry believe that the price and environment of high-definition applications are no longer a problem. With the first-tier cities in China launching "arms competition" for high-definition surveillance applications in recent years, the high-definition surveillance market has matured.
High-definition monitoring systems have been built all over the country
It is understood that the construction and application of high-definition surveillance systems have become an important part of the wave of construction of video surveillance systems throughout the country. Especially in first-tier cities, HD has gradually become mainstream. On September 4, Luo Cheng, manager of the technical department of Hengye International Holdings Group Co., Ltd., told reporters that the trend of high-definition applications nationwide has become very obvious, especially in developed coastal areas.
On August 30, the reporter learned from the Traffic Police Brigade of Daya Bay District Public Security Bureau in Huizhou City that the district is currently focusing on the construction of a traffic monitoring system. Not long ago, the entire district ’s road traffic monitoring intelligent command system (center) has been put into use. . At present, the district has installed 16 security video bays on the main access roads, and installed nearly 300 security video surveillance points. At the same time, this district will also add 4 security bays and 100 security cameras. It is worth mentioning that, while retaining the original number of security bayonet points, the entire Baya Bay area will replace the original bayonet camera from the previous standard definition to high definition.
At the same time, since 2006, Xiamen City has invested more than 500 million yuan to initially build a video surveillance network covering the entire city. Among them, Xiamen City “City 110 Command Center—Divisions—Police Station†three-level video surveillance platform networking has been initially formed. For Xiamen, the application of high-definition monitoring is naturally the focus. It is reported that high-definition surveillance systems have been adopted in all key sectors of Xiamen, such as transportation and banking. In the off-island areas of Xiamen where the economy is relatively backward, the Xiamen Municipal Public Security Bureau has made great efforts to formulate the overall plan of the off-island security monitoring system. The focus is to invest more than 6 million yuan in the construction of a batch of high-definition video surveillance systems to realize the video Integration and networking of monitoring system resources.
Similar information came from Qingdao. On August 31, the Comprehensive Management Office of Licang District, Qingdao City announced that it is expected that by the end of this year, the first batch of 500 1080P high-definition quality monitoring equipment will be built in Licang District. According to Xiao Zheng, deputy director of the Comprehensive Management Office of Licang District, Qingdao City, in order to strengthen social security, the district government funded and led by the Comprehensive Management Office, installed a dynamic social monitoring system in the district, and added 1,000 high-definition cameras. The construction period is expected to be 3 In 2015, the first batch of 500 is expected to be put into use before the end of the year. The main installation areas are on main roads, under bridges, school areas, commercial districts, and the soon-to-be-built North Railway Station.
The price may "no longer be a problem"
For the surveillance market, high-definition surveillance used to be synonymous with high prices, and because of the high price and immature market, there have been few application cases.
Compared with traditional analog surveillance, the technical threshold for high-definition video surveillance is higher, which is a big challenge for many domestic security companies. A senior technical director of a monitoring company in Shenzhen told reporters: "Technologies such as auto exposure, auto white balance, auto focus, low light enhancement, backlight compensation, electronic shutter, frame accumulation, and color correction are all difficult problems to overcome. So, although now Many monitoring companies have displayed millions of high-definition products at the exhibition, but not all companies can produce energy, and only a few manufacturers have the strength to carry out high-definition mass production. "
At the same time, the application of high-definition monitoring is systematic, with high requirements on the front end, back end and transmission. Luo Cheng told reporters that with the development of the monitoring field, the industry's technical requirements on the back end of millions of high-definition monitoring have increased. "Specifically reflected in the requirement for higher VGA output resolution and higher decoding and processing performance." Some insiders believe that the poor domestic transmission environment is also a bottleneck restricting the development of high-definition.
As HD is gradually known and accepted by the industry, the cost problem seems to have eased. High-definition surveillance equipment has high-end technology and accessories, and its cost has always been higher than that of traditional analog cameras, so the market price remains high. However, Ju Peiquan, manager of Hengye ’s international marketing department, said: "The price problem is not necessarily the hindrance to the maturity of high-definition surveillance market. In the past, the market ’s reluctance to accept high-definition due to cost problems was based on the market ’s lack of understanding of high-definition, just like when the computer first came out It is also expensive, but because there are not many people who understand it, it is only hot in the smaller areas of IT and Internet. Later, as the Internet became popular and computers gradually entered people ’s lives, market acceptance increased rapidly, of course. The price has also dropped. In fact, the price of high-definition surveillance products is also lower than the original price. I think that when the market acceptance goes to a higher level, its price will also drop. "
High-definition face recognition monitoring technology emerges
According to Luo Cheng: "Generally speaking, the systematic HD construction in all parts of the country represented by safe cities is led by the government and the public security system is responsible. The construction of the project and the entry of equipment refer to the 28181 agreement, which is the national standard GB / T28181-2011, this standard is a non-compulsory standard, which has become a mandatory standard in some provinces and cities, but some provinces and cities have not enforced it, such as Guangdong province. "It is reported that the standard mainly regulates external interface software . Luo Cheng said that in terms of hardware, the national standard has no targeted specifications, and most of the high-definition equipment on the market mostly conforms to market application standards.
In terms of the application of new technologies, face recognition technology has begun to emerge in the market. The 1,000 high-definition surveillance systems to be applied in Qingdao this time need to include a face recognition system. Xiao Zheng introduced that by the end of this year, the first batch of 500 1080P high-definition monitoring equipment will be built. In terms of technology, this batch of monitoring equipment is currently the highest standard in Qingdao, all of which are high-definition probes, and the video recording is 1080P HD 360 degree rotation. "The sharpest function of this new generation of monitoring systems is the face recognition system that often appears in film and television works. In the face recognition system, the camera can automatically capture the front and side of the person, and it is automatically chasing with the database. After comparing the facial photos of the suspected suspects, they can automatically alarm after recognizing the image. After the system is completed, it will be networked with the public security organs to share information with public security police stations, traffic police and other departments. "Xiao Zheng said.
Monitoring face recognition is still a high-end application. At present, the domestic monitoring manufacturers with such technical strength are rare. Luo Cheng revealed: "Dynamic monitoring of face recognition is quite technically difficult, because the face is always in a state of motion, and the image obtained when the camera locks the face is often unclear and cannot achieve the effect of recognition analysis. However, it is static In some cases, camera recognition is relatively easy, so there are still a number of domestic surveillance manufacturers that have static surveillance face recognition technology. The high-end technology will naturally make its market price high. This kind of camera with dynamic face recognition is compared with a camera with the same conditions. The price is about 50% more expensive. "
It is reported that the application of face recognition monitoring technology in the market has begun to heat up. On June 19, in an industrial and commercial bank in Gulou District, Fuzhou, the reporter saw two "Hikvision" smart face recognition ball skills guarding the bank's gate and lobby. In many domestic high-speed rail stations, reporters have also seen many applications of such monitoring systems.
