According to relevant data, the overall market for video surveillance in China will reach US$1.7 billion in 2010. Faced with such a large market, the development of high-definition technology has become an important topic for domestic mainstream manufacturers, which directly led to the application of intelligent identification technology in video surveillance. It can be foreseen that the market for high-definition intelligent surveillance will become larger, and video surveillance will also transform from "passive defense" to "active defense."
$1.7 billion! "Active security" sounded the horn of market capacity According to relevant data, in 2010 the entire domestic video surveillance market capacity will reach 1.7 billion US dollars. Faced with such a large market, the development of high-definition technology has become an important topic for domestic mainstream manufacturers, which directly led to the application of intelligent identification technology in video surveillance. It can be foreseen that the market for high-definition intelligent surveillance will become larger, and video surveillance will also transform from "passive defense" to "active defense."
Due to the increasing complexity of social security issues in recent years, safety precautions have become increasingly important. Video surveillance is one of the swords for security protection and an indispensable technical preventive measure in many fields. Here, we also put forward higher requirements for security precautions. After several changes in security monitoring, it has rapidly entered various industries and applications, and has been rapidly applied to various industries from traditional application fields such as finance and safe cities. In industries such as telecommunications, military, energy, transportation, education, municipalities, and chains, etc. The more and more "entrusted with important tasks." It has been recognized by more and more ordinary people and is closely related to people's lives. It is also the direction of continuous efforts of security companies. With the increasing voice of “I want to see more clearly†in 2010, this directly promotes high-definition intelligent surveillance to gradually become the mainstream of the market. The key significance is that video surveillance will be implemented from “passive security†to “active securityâ€. The transformation.
The application of high-definition intelligent monitoring system promotes active defense against deterrence and post-reduction of actual video surveillance. It has been well witnessed in practical applications in various industries. However, how to make surveillance more deterrent, so that monitoring will play a preventive role, how to do it? For example, how to see a person's facial features in a bustling downtown; how to clearly see the vehicle's license on busy highways while seeing the facial features of the passengers and passengers; in crowded and bustling subways, entrances and exits to parking garages, etc. How can we quickly and accurately find the goal; how to intelligently identify insecurity in the surveillance area and initiate prevention plans? ? These demands are fiercely hitting the nerves of the security industry and promoting the continuous innovation of security technologies.
Driven by the promotion of monitoring the network trend and market demand, high-definition and intelligent monitoring technologies have achieved major breakthroughs and entered the practical application of major security projects. This indicates that video surveillance has entered the era of high-definition, and high-definition and intelligence have become video Monitor the new age theme. With the continuous emergence of high-definition technologies and products, the real-world application of high-definition intelligent surveillance systems will accelerate the seamless integration of video surveillance systems with other security subsystems, and further promote seamless integration between security systems and industrial business management systems. This is video Monitoring brings more room for development.
The current industry mainstream application has a resolution of CIF (100,000 pixels) and a maximum of 4CIF (400,000 pixels), resulting in an existing monitoring system. The main function is to record the events, and “not clear†in more key details. †The result is that monitoring efficiency and monitoring value are greatly reduced.
High-definition surveillance achieves resolutions of 720P and above, ie, megapixel resolution, and it brings several distinct advantages: high image resolution and access to more critical details; monitoring of single surveillance points , You can reduce the number of points, you can pay attention to multiple details at the same time; high-definition images, can greatly improve the accuracy of intelligent video analysis, and lay a solid foundation for the realization of intelligent monitoring.
The core of intelligent monitoring lies in intelligent video analysis. It uses moving target detection, tracking, and classification technologies for the input video stream. The image within the video target is identified by an image recognition algorithm such as background modeling, target segmentation, tracking, and classification. The transformation of event parameters enables real-time detection and post-event detection of various emergencies. Based on intelligent video analysis technology, various functions such as behavior analysis, bank protection, license plate recognition, traffic statistics, and intelligent tracking can be implemented.
Through the intelligent monitoring system, it is possible to proactively warn about suspicious targets and abnormal events and initiate corresponding levels of prevention plans, thereby greatly improving monitoring efficiency and monitoring value, and providing strong guarantee for safety management. At present, the value of intelligent monitoring systems is increasingly prominent in important fields such as the judicial, financial, cultural, and energy industries. For example, identification of the license plates at entrances and exits of the prisons, vigilance around outdoor roads and walls, and behavioral analysis of ordinary prisons, toilets, and prisons. , intelligent tracking of visiting channels; intelligent identification and alarm for ATM sticker strips, installing readers, bank indoor fighting and fighting (strenuous exercise), trailing and other behavior detection, statistics of entrance and exit traffic, etc.; business in scenic spots, shopping malls, etc. The use of traffic statistics system in public places to obtain business analysis data; at night during non-open hours, anti-theft measures for museums, warehouses, valuable products, etc., perimeter prevention of oil extraction machines (sauerkraut machines), alertness of areas near oil extraction machines, etc.
Therefore, the application of high-definition intelligent monitoring system, so that "see more clearly" is no longer a dream, but also make active prevention become a reality.
High-definition monitoring The long-term high-definition video under an overall solution is not only the HD video capture, ie, the installation of a high-definition camera or high-definition dome camera, but the video capture, encoding, transmission, storage, control, and decode output to the center. In this sense, high-definition monitoring does not depend on a certain product or a certain number of products. It must be a protracted war. What is needed is an overall solution.
In order to meet the urgent need for high-definition monitoring, a small number of domestic digital monitoring companies, based on deep professional accumulation of research and development, has now launched a complete high-definition monitoring solutions, covering the front-to-back high-definition product system. Among them, the front camera is more representative of the 1.3 million pixel CCD, 2 million pixel CCD, 5 million pixel CCD high-definition camera, can perform full-real-time monitoring, that is, 25fps high-definition monitoring, and industry-leading pure digital high-definition camera, It is very different from the general network camera: First, compression, network cameras generally use MPEG-4 or H. The 264 standard performs encoding compression, while the digital camera directly outputs digital image streams without compression; the second difference is in the transmission mode, the network camera uses the IP network to transmit the compressed code stream, and the digital camera must use optical fiber or HD. Digital interfaces such as SDI transmit digital video streams.
Realizing high-definition video capture is only the first step in completing the HD monitoring system. Next, high-definition encoding and high-definition stream transmissions are required, or uncompressed high-definition digital streams are directly transmitted to enable exchange control of high-definition digital signals, as well as high-definition stream access and high-definition display. It is particularly important that, as the “command center†of the entire system, there must be a powerful set of high-definition management platforms to meet the centralized/distributed management of high-definition video streaming and management signaling. Only in this way can the high-definition monitoring system be able to successfully complete the "high-definition monitoring" task.
At present, a few excellent monitoring companies in China have gone through years of painstaking research in video processing and video analytics technologies, have their own core technologies, launched a complete high-definition intelligent surveillance product and overall solution, and obtained major international projects. Widely used.
In the high-definition surveillance era, compared with leading international companies, domestic video surveillance companies represented by these companies are not behind. They have proved their intelligence in HD through successful application of full-line products and solutions on major projects. Monitor the strength of technology, products and services in the field.
Popularization of high-definition issues to be solved From the perspective of advancement of high-definition applications, due to a variety of factors, it must be a gradual process. In this process, many problems need to be solved: First, many factors such as cost, user acceptance, and maintenance should be taken into consideration. In the deployment of the system, multiple solutions are needed to enable the smooth transition of all links in the original system. Progressive upgrade. Second is the storage problem. Since high-definition video requires more storage space, transmission bandwidth, and a higher-required network environment than ordinary resolution, high-definition applications must also have diverse storage solutions.
In high-definition upgrades, since the amount of analog cameras currently held in most domestic projects is still large, it is not realistic to update all network cameras when the system is upgraded or rebuilt. Therefore, hybrid DVRs (H-DVRs) are generally used. Ways to solve compatibility issues. Hikvision's DS-9000 series hybrid DVR supports both analog camera access and HD network camera access. While maintaining user habits, it also reduces the cost of user training and maintenance, and the transition and upgrade In the process, the user's input is protected to the greatest extent.
In the storage sector, if a large-scale application environment (more than 1000 roads with front-end monitoring points) has no problem in terms of capital and network, it will adopt a centralized storage method, which is usually IPSAN. However, such projects are still very rare, mainly focusing on High-end market. Most small and medium-sized network applications mostly adopt the distributed storage and centralized management mode. At this time, NVR products can be used.
There is also a problem that deserves attention is that in the existing networked centralized monitoring system, especially on a certain scale of systems, the types and quantities of devices are numerous, VCR, encoder, optical transceiver, decoder, video matrix, video distribution The devices ... and so on are piled up in cabinets, and video cables, network cables, control cables, optical fibers, and power cables are intertwined, which brings great difficulties to management and maintenance. How can the user's energy be freed from "how to integrate the system and manage it effectively", focus on the results achieved with the system, and quickly and easily transition the system to HD?
Raise the overall level of the network monitoring industry to participate in the competition! ! !
Since it is a technological leap, the boom period under the transformation of the industry, then the survival of the fittest is inevitable! The competition of high-definition surveillance includes many aspects, mainly including: coding technology, network technology, video processing technology, camera technology, etc. The most basic and the most important one is the breakthrough of video processing, sensor technology and innovation of codec technology. The mastery and breakthrough of this type of technology often need to be realized through deep accumulation of digital video processing technology research and development and algorithms.
For example, video processing technology, as a replacement product, HD video camera in the video processing technology is not limited to analog video camera processing technology, but also includes image enhancement technology, such as image noise reduction, debounce and so on. This kind of video processing technology must be implemented in the camera's ISP through a special algorithm, which is impossible for analog cameras.
Then there is coding technology. For the moment, H. 264 is still the best choice for security surveillance video coding standards. However, using the same coding standard does not necessarily mean that everyone's video coding technology is at the same level. Because early video coding standards were not designed for security applications, they must be adapted for security monitoring.
Therefore, the coding optimization technology and experience truly determine the overall performance of video surveillance applications. It can be seen from this that the development technology of high-definition products has a high threshold and large investment. If high-definition monitoring products and solutions can be completed, the overall level of the network monitoring industry will be promoted.
At present, some international first-line companies have made some progress in the development of high-definition products. Some domestic companies with DVR/DVS R&D backgrounds have also been involved in the development and production of high-definition products. These enterprises are familiar with the related technical applications of image processing and DSP, and have a strong R & D capabilities, and have a deep understanding of security, so they have a technological innovation and change the soil, easier to achieve technical breakthroughs in high-definition products . In particular, through years of accumulation, Hikvision has made major breakthroughs in independent research and development of ISP technology, which enables them to better handle video and flexible use of various types of Sensor chips to enrich product forms. The price is higher.
