HD monitoring market development analysis

Under the impact of the high-definition wave of the video market, video surveillance can't stop them from catching and sweeping. Only by adapting to the trend can we take the initiative. Many security companies saw this trend as early as a few years ago and began to Test water. In 2006, the concept of "Millions of High Definitions" began to appear in the security industry. Waves and trends will soon be formed. It can be said that "go faster, come faster!"

The promotion of high-definition monitoring demand Throughout the development of high-definition video surveillance, not only the development of technology and maturing factors, but also driven by market demand.

In terms of demand, in the past, many monitoring systems had problems with unclear monitoring images. “Unclear” became a common complaint for monitoring users, which also affected the popularity of monitoring systems to some extent.

"Unclear" has made many surveillance systems scare people. Although there are images, the images are very vague and do not help solve crimes. There is not much use value. For instance, the case of Zhou Kehua, a major case that has caused a stir throughout the country not long ago, is typical. example.

Zhou Kehua, as a producer of the “Su Xiang’e series of gun robbery and murder”, from 2004 to 2012, had six gun robberies and murders in Chongqing, Changsha, and Nanjing, killing and killing many people, looting large amounts of cash, and even shooting sentry robberies. Guns were listed as A-level wanted criminals by the Ministry of Public Security.

In the process of Zhou Kehua's crime, the surveillance system also captured a lot of images, but these video images were taken out after the incident, and almost all the suspects did not capture a clear facial image. Because the surveillance image is not clear, it is difficult to determine whether the suspect is the same person, causing difficulties in solving the case, so that Zhou Kehua can escape multiple times and commit crimes several times. The task force can only analyze and judge through its walking gait and grasp its physical characteristics. The police finally obtained two clear facial photos from the internet at their Internet cafes, which were frequently accessed and screened through video, to lay the foundation for locking down suspects and obtaining project breakthroughs.

Another typical example is the electronic police and bayonet monitoring. The main function of the electronic police and bayonet monitoring is to continuously record all the vehicles and number plate images of each motor vehicle used to monitor the road in real time. However, in the past, the electronic police only captured information such as license plate number, license plate color, vehicle body color, vehicle type, etc. of the driving vehicle, but failed to capture information such as the facial features of the driver, and some even the license plate number could not be captured clearly. It has brought certain difficulties for timely detection and handling of cases such as traffic violation investigation, traffic accident escape, and robbery of motor vehicles.

The electronic police not only requires the surveillance camera to have a high license plate recognition rate, but also requires that all details of the vehicle and the facial features of the driver be clearly displayed on one photograph. Therefore, the clarity of the front-end acquisition equipment of the monitoring system must be improved. This problem requires security companies to research and solve.

The promotion of demand for video image intelligence analysis For video surveillance systems, only high definition is not enough, "seeing clearly" but also "perfect", you must install the "brain" to the monitoring system, so that the period has "intelligence" in order to Better use of the monitoring system. This is because the social dynamic security monitoring system is a huge system with many points. Therefore, it is impossible to supervise and monitor the monitoring screen manually by the monitoring personnel. It is not only costly but also unable to meet the monitoring needs. Physiological studies have shown that people's vision "tolerance" is limited, a person can only monitor at most 9-10 monitoring screens at the same time, and more then exceed the limit, resulting in many screens do not come over, and sometimes miss important monitoring information. At the beginning of the construction of the city’s alarm and monitoring system, many places had even had to recruit a large number of monitoring check-in personnel to enrich the monitoring room to assist in monitoring the monitoring screens. In some places, monitoring image monitoring teams were even established. This human-sea tactics not only greatly increases the operating costs of the monitoring system, but also does not help maximize the effectiveness of the monitoring system.

In 2008, the Shanxi police seized over 50,000 hours of surveillance footage from more than 80 highway toll stations in order to crack down on the “5·29” super gun robber and murder case in Fugu County. It was finally monitored from these 50,000 hours. The video found useful clues and eventually broke the case. After the Su Xiangyu series of armed robbery and murder suspects, Zhou Kehua, fled for crimes in Nanjing, the Nanjing police transferred thousands of civilian police to read, view, and screen all the city’s surveillance videos. It also spent a lot of manpower and energy. Video recording is equivalent to 830,000 films.

In fact, in all surveillance image information, only 1% or even less than 1% is useful, and 99% of information is useless information. But it is precisely with this 99%% of useless information pave the way, only 1% of useful information was precipitated, thus helping the police to crack the case.

On the other hand, the role of the video surveillance system in the past mostly only stayed on the ex post facto, with the continuous application of the city's alarm and monitoring system, the use of video surveillance to detect and stop the occurrence of cases, improve the public security organs to control the dynamic social security , to become a new higher level of demand. These all put forward a new and higher level demand for the monitoring system - intelligent monitoring.

Video surveillance intelligence analysis is actually like Google, Baidu, Sogou and other search engines. Twenty years ago, when we needed to search for information, we could only go to the archives or libraries. When we read newspapers and magazines in the same way as we do in the haystacks, we may need to consult dozens or even hundreds of books and newspapers to find out. Need something, then use the pen to copy the relevant information found in the notebook, go back and organize. This process may take an afternoon or even a full day, which can be described as time-consuming and labor-intensive. But today, with search engines, we only need to enter keywords and click the mouse. Thousands or even tens of thousands of information related to keywords will instantly appear in front of us.

So, should the video surveillance system also have similar functions? Should it also have intelligent search function? This is a challenge for traditional surveillance. This problem also needs security companies to research and solve.

The technical requirements and development process of high-definition surveillance are actually in the field of video surveillance. HD and megapixels are not the same thing. HD and megapixels are generally referred to as having clearer and higher levels than ordinary surveillance cameras. Therefore, they are very close in terms of many measurement points and effects, but in reality, they are very different. The so-called high-definition, in fact, is not just a simple concept, it has a very clear measure. According to the HDTV standard, there are currently only three types of HD video surveillance formats that are truly compliant, namely 720p, 1080i, and 1080p.

In 2006, the industry put forward the concept of "Millions of High Definitions" and it was quickly recognized by everyone. The minimum number of pixels in "Millions of HD" is actually 1.3 million pixels and not 1 million pixels. "Millions of HD" is just called, easy to remember and loud, so the industry is used to calling it "million HD".

But for surveillance cameras, if only front-end high-definition lenses, without high-performance sensors or other video processing technology, then the multi-megapixel lens may not be able to get high-definition image effects. Therefore, high-definition video surveillance must achieve high-definition results from front-end video capture, video transmission, video storage, video processing, and video display to achieve the ultimate high-definition effect.

At present, the high-definition video surveillance system has gone through three generations, namely: "Millions HD" IP camera + video management software model for the first generation of high-definition monitoring systems for small and medium-scale monitoring sites; to meet the needs of large-scale monitoring systems High-definition IP camera + optical transceiver + decoder + HD display + HD storage mode of the second generation of high-definition monitoring system; and the fusion of analog SD, IP high-definition, HD-SDI high-definition technology of the third generation of high-definition monitoring system.

With the rapid development of high-definition surveillance technology, traditional analog surveillance is not far behind, and the image clarity is constantly improving. There are analog high-end products represented by 960H.

Technical requirements and development history of intelligent video analysis Intelligent video analysis technology is a new type of video surveillance technology based on image processing and pattern recognition. In short, it is to discover the objects that need to be monitored in the monitoring scene, and to track and analyze them. In a timely manner, “abnormal” behaviors are discovered, alarms are triggered, and corresponding measures are taken to intervene. The intelligent analysis of video images should incorporate functions such as behavior recognition (including gait, abnormal behavior, etc.) and face recognition, and be deeply combined with these technologies.

Video Intelligence Analysis (IVS) has two meanings. The first is the use of computer image visual analysis technology. By presetting different alarm rules in the surveillance scenes of different cameras, the alert zone warning lines appearing in the video area break in, and articles Analysis of legacy or missing, retrograde, abnormal population density, etc. Once the target has violated the predefined rules in the scene, the system will automatically issue an alarm. Intelligent video surveillance technology uses computer's powerful data processing functions to perform high-speed analysis on massive data in video frames, filter out information that is useless or that the user does not care about, and only provides useful key information for the monitor; the other is the face The recognition technology integrates in depth, automatically detects and recognizes the facial features of the characters, and identifies or verifies the identities of the characters through comparison with the face database files, for example, through quick comparison, to retrieve the corresponding characters in the face database (e.g., Wanted crimes), and follow-up monitoring. For example, in the face database of the police, the face information of the gun robber suspect Zhou Kehua was established. By linking with the intelligent monitoring system, once the Zhou Kehua is found in a certain city or a certain place, the system will immediately send an alarm message. , And show the time information of the suspect and the location of the camera, the police can quickly track the trajectory through the monitoring system, and inform the ground police to track and arrest it.

Intelligent analysis not only has accurate post-event image retrieval functions, but also importantly, it can help us to achieve "prevention beforehand", anticipate and discover crimes in advance, and take timely measures to deal with them, so as to protect the safety of people and property. Intelligent video analysis and monitoring system's functions such as “resolving legacy items” and “remaining area cues” can enable security monitoring personnel to perceive and discover abnormal behaviors in advance, and quickly transmit the warnings to police officers on the street to make coping strategies in advance. Some people have left behind suspicious objects (such as disguised explosives) in public places or people have stayed in the vicinity of sensitive areas for long periods of time (watching for crimes). Intelligent video analysis systems can provide early warning. This is not possible with traditional video surveillance systems.

Due to various reasons, the current development and application of video intelligent analysis technology is somewhat lagged behind HD video surveillance, and it is far from the high-definition surveillance market. There are not many large-scale application projects, and the technology needs to be further improved. Intelligent analysis can only form a large-scale application market on the premise of meeting high-level applications.

After the "911" incident in the United States in 2001, some agencies in the United States and Israel that are committed to the research of security technologies began to join the ranks of security technology research. The intelligent video analysis technology has made a breakthrough in this process and has become a video surveillance technology. Highlights. 2002-2005 is a clear peak period for the development of intelligent analysis technology. Objectvideo, ioimage, OV, Verint, Mate, Cernium, Milestone, etc. have made achievements in this area. Since then, there have been mergers and acquisitions and integrations between these companies due to competition and business development needs.

The development of domestic intelligent video analysis market is about three to four years later than Europe and the United States. There are not many companies with independent intellectual property rights and R&D capabilities. Some companies that focus on the research of intelligent video analysis technology are too optimistic about the market prospect of video analytics. Ignoring the development of the traditional video surveillance business and getting into a difficult business situation, it changed from a pioneer to a martyr. This shows that the era of large-scale application of intelligent video analytics has not really arrived.

The demand for driving demand for high-definition monitoring was first proposed by the public security bureau, and in the short space of several years, the initial vision became a reality. As technology matures, application needs rapidly increase from point to point.

In 2009, the Ministry of Public Security successively issued the "General Technical Conditions for Automatic Recording System for Red Lights", "General Technical Conditions for Intelligent Monitoring and Recording Systems for Road Vehicles" and "Technical Specifications for Image Obtaining of Road Traffic Safety Violations". "Automotive license plate image automatic identification technology specification" and a series of standards. In December of the same year, the Public Security Department of Jiangsu Province launched the “320 Project”. The project plans to build a road monitoring network within the province of Jiangsu. Every three kilometers of the city’s roads in the province will establish a capture point for vehicle monitoring, and other roads. Every 20 kilometers to establish a monitoring capture point. In the final stage of the equipment, the project made a minimum requirement of 2 million pixels for the front-end camera. Once the news broke out, there was an uproar in the industry. The major monitoring companies rushed to launch various high-definition monitoring solutions for public security.

In 2010, local security bayonet project and electronic police project began to adopt a second-generation high-definition monitoring system on a large scale, which promoted the development of the entire video surveillance system to high-definition, and the high-definition surveillance market began to enter a stage of rapid development. Therefore, the industry will refer to this year as the "HD first year."

High-definition network cameras are the hottest products in the video surveillance industry in the past three years, and their share in the entire camera market is close to 15%. According to the survey, the HD camera market grew by 38.6% in 2012, ranking first.

In the video display market, high-definition has become the mainstream of the monitor display market, supporting 1080P full HD display monitors and becoming the preferred device for monitoring various application areas. The standardization application of 1080P in the color TV industry is already very mature. As a monitor industry that has the same relationship with color TVs, there is no doubt that high-definition applications will also go ahead. Therefore, 1080P has become the target pursued by major monitor manufacturers.

In the next few years, the application of high-definition surveillance market will enter the blowout period in 2012. Guangdong Province has promulgated the “Three-year Plan for the Construction of Social Security Video Surveillance System in Guangdong Province (2012-2014)” and proposes that the province will add another 96 within the next three years. 10,000 first- and second-class social security video image collection points, and at the same time, 2,750 new HD security bayonet sets; the Tianjin Public Security Bureau also issued the “Implementation Opinions on Strengthening the Construction of the Technology Prevention Network System in the City”, and proposed to be in the city. Street pavement planning and construction of 105,000 high-definition video surveillance sites and 900 high-definition electronic bayonet targets; the Shanghai Municipal Education Commission released the "Twelfth Five-Year Plan for Development of Campus Security Technology Prevention in Colleges and Universities in Shanghai" last year, demanding Shanghai college campuses. The monitoring system is fully HD, and the time schedule is listed: By the end of 2016, all colleges and universities in the city have achieved HD video surveillance;

Liye District, Qingdao City, Shandong Province plans to install 1,000 high-definition surveillance cameras within three years, and the system will be upgraded through face recognition and warning; 2012-2013, Quanzhou, Fujian Province will build 8000 high-definition video cameras; Guangxi The construction of the third phase of the “Tianwang” project in Liuzhou City began to use large-area high-definition cameras. Compared with the previous two standard-definition cameras, it increased from 400,000 pixels to 1.3 million pixels. After the third phase, 2,800 high-definition cameras were installed in the fourth phase of the “Tianwang” project, of which 1,100 were used to replace the standard-phase cameras of Phases I and II; Xiaohe District of Guiyang invested more than 50 million yuan last year and installed 850 high-definition video surveillance. Camera; In 2012, the “Tianwang” project in Liupanshui City, Guizhou Province with a total investment of more than RMB 1 billion was launched. This project will become the first super-large safe city construction project based on HD network video surveillance in China. This is just the tip of the iceberg for HD video surveillance applications.

In August 2012, the Ministry of Public Security issued the newly revised "Regulations on the Application and Use of Motor Vehicle Driving Licenses," which will come into force on January 1, 2013. According to the new regulations, red lights, yellow lights, and school buses will not be punished and deducted. Points will be deducted for driving a mobile phone and not wearing a seat belt. Known as "the strictest rules in history." In order to avoid traffic police enforcement disputes and disputes, the application of high-definition electronic police will become even more popular, and will drive the application of high-definition surveillance systems in other areas, especially law enforcement agencies. In November 2012, the Shanghai Municipal Public Security Bureau’s Technical Protection Office issued a “Digital Video of the city”. The notification of the basic technical requirements of the security monitoring system means that, starting from January 2013, the Shanghai market surveillance system application will push digital cameras such as IP network cameras and SDI cameras, and traditional analog cameras may gradually fade out of the market. .

From this we can see that in the future, high-definition surveillance applications will become more and more widespread. Especially in the new round of city alarm and monitoring system construction and system upgrade, the application of high-definition video surveillance will become the focus.

Driven by technological development If the market demand is a wheel that drives the development of the intelligent high-definition video surveillance industry, then technological development is another wheel that drives the development of the intelligent high-definition video surveillance industry. The unique "wheel" is difficult, two-wheel drive, so that intelligent high-definition video surveillance quickly into the fast lane of development.

Strictly speaking, if there is no mature technology, even if the market demand is strong, it can only be a subjective desire and appeal that cannot be satisfied. However, it is gratifying that the rapid improvement of video surveillance technology is almost synchronized with the strong demand of the market.

In terms of technology, chip manufacturers such as TI continue to improve chip performance, providing technical support for the realization of high-definition monitoring.

With the continuous development of CCD and CMOS, the clarity of video surveillance cameras has been continuously improved. The horizontal resolution of analog cameras has grown from 380 lines to 480 lines, to 540 lines, 600 lines, and 650 lines. When it came to line 650, a network HD camera came out.

In the age of simulation, it is generally considered that the horizontal resolution of a camera is higher than 480 lines, and it can be called a high-definition camera. For digital cameras, the resolution of more than 720P can be referred to as high-definition cameras. This "standard" was basically recognized by the industry in the following years.

Fortunately, no matter if it is an analog system or a digital HD system, the pace of innovation has not stopped for a moment. At the beginning of the development of high-definition surveillance, IPC was almost the only solution for high-definition applications, followed by HD-SDI solutions. In 2012, another manufacturer introduced a new HD solution—HD-MDI, the high-definition surveillance market. It has already presented the three-way situation of IPC, SDI and MDI. At the same time, the analog surveillance system was not discouraged by the emergence of high-definition, but also quickly followed up with an upgraded version of the analog high-line product 960H (also known as the analog HD solution in the industry). This technical game has brought about splendor for the industry and has also become a driving force for the development of the industry.

After the waves of the Yangtze River push forward, the development of technology will never stop. With the improvement of technology, in the next few years, the higher-clear products will be popular, and the current high-definition will not be called HD, but a "pave" for high-definition development; It may take less than a few years and the era of large-scale application of intelligent video analytics technology will come. With its unique charm, it will lead the market.
