Analysis of the Development of Domestic Video Surveillance Equipment

one. The development of video surveillance display equipment market in recent years The rapid development of science and technology has led to advances in security application technology, especially in the areas of network broadband, computer processing capabilities, storage capacity, etc., which have been rapidly improved. With the advent of various practical video information processing technologies such as intelligent analysis, the video surveillance display technology has also achieved considerable development and progress. At present, domestic video surveillance display technology has entered a new era of digitization, networking, and intelligence.

Video surveillance display is an important part of video surveillance applications. It involves the research fields of video processing, video signal transmission and signal processing. Video communications, processing and decoding are important technologies for video surveillance display. Looking at the development of the entire video surveillance display device market, the development of its video surveillance display technology has undergone three generations: the first generation is the traditional analog system (CCTV), the second generation digital-analog hybrid system (DVR/NVR), and the third generation is completely Digital systems (webcams, network monitors and video servers).

The first generation was an analog system. Because of the limitations of the technical conditions at the time, the front-end cameras used analog cameras and the transmission network was also simulated. The back-end used analog to store video data and display monitoring images. Therefore, the entire security system is simulated. Although the system is easy to establish, there are problems such as short image storage time, blurred image quality, and a short transmission distance. At present, the analog monitoring system has gradually withdrawn from the market.

The second generation is a digital video surveillance system based on analog cameras and digital hard disk recorders. With the improvement of computer processing capabilities and the development of video surveillance technology, people use the computer's high-speed data processing capabilities for video capture and processing, using the monitor's high resolution to achieve multiple images and high-definition display of the image, which greatly improves the video image. The display quality of this computer-based console system is called the second-generation digital local video monitoring system. This system still uses analog signals for transmission, and the transmission distance is short, which does not fundamentally solve the bottleneck of image transmission. problem.

The third generation is a fully digital video surveillance system based on network cameras and video servers. The system focuses on the compression, transmission, storage, and playback of digital video, and features intelligent and practical image analysis. It is suitable for long-distance transmission, easy search, and easy system management and maintenance. At the same time, the quality of the image and the monitoring efficiency have been greatly improved.

The basic functions of the above three generations of systems are the ability to display real-time monitoring screens and save videos. They only have simple motion detection, intelligent analysis, and alarm functions. They do not have the ability to carry out artifacts, string detection, behavior detection, area intrusion, and crowd aggregation detection. This requires security and surveillance professionals to constantly obtain continuous observation from the massive data to obtain the required data. Therefore, the above three video surveillance systems all belong to non-intelligent video surveillance systems. “Worry to miss the goal and not be able to give early warning "It has become an urgent problem for the current monitoring system. With the development of security technologies in recent years, technologies such as imaging equipment, video compression, transmission, storage, and processing have developed rapidly and gradually matured, but these do not change the status of passive monitoring. Passive monitoring has the ability to identify whether or not ** exists. Features, can not automatically analyze and report the video content, and all this work still depends on the monitor for continuous judgment and analysis. The lag of intelligent video analysis technology has seriously hindered the development and application of video surveillance systems, resulting in the existing video surveillance systems can only complete the recording of monitoring content, but only provide evidence for post-mortem analysis, and it is difficult to achieve real-time video event detection and analysis. And alarm.

With the rapid development of the market for video surveillance and display devices, more and more companies have taken a fancy to this “cake”. Some video surveillance companies that do not originally display devices have started to get involved. Some manufacturers that originally only used commercial display devices Began to enter the video surveillance display market. At the same time, many new video surveillance display manufacturers have emerged in the industry in recent years. As more and more companies enter the video surveillance display market, the industry has become more competitive, which has caused some impact on video surveillance display equipment companies. Some enterprises with strong technical strength have also begun to adjust their strategies, closely following the development trend of the video surveillance market. , to digital, network, intelligent direction.

two. Problems faced by the video surveillance display device market At present, the demand for video surveillance display devices is still strong, and the market is gradually changing from analog to digital. Although the development prospects of domestic video surveillance display devices are broad, due to features such as low entry barriers and relatively high profits, the industry has attracted more and more small companies to enter the market of video surveillance display devices. However, video surveillance companies that really focus on product innovation and R&D show relatively few companies. Most companies tend to focus on obtaining economic benefits in the short-term, thus forming the current situation of low-end product proliferation in the industry and scarcity of high-end products. In addition, as the history of video surveillance display devices in the industry for mutual OEM and mutual OEM, has formed a long history of many products in the technical parameters, appearance, function and other aspects, did not reflect the obvious difference Personalized features. In 2013, although the profitability of video surveillance and display equipment was reduced and some large manufacturers joined in the industry to some extent inhibited the unfavorable competition in the industry, and eliminated some of the small companies without innovative capabilities, it is still impossible to fundamentally reverse it. The situation of mutual plagiarism and the homogenization of the video surveillance display equipment market are still severe.

There are three main reasons that cause the problem of homogeneity of China's video surveillance display equipment: First, from the origin and development history of video surveillance display equipment, the domestic video surveillance display equipment started relatively late. At the beginning of development, it was through agency abroad. Brands, after a certain period of time to imitate and create, to the current industry has not yet formed an innovative concept; Second, video surveillance display equipment companies in recent years, although has achieved rapid development, but the company's management philosophy, The process system and the talented staffing are seriously lagging behind the scale growth of the industry, and have not formed a uniform standard for the industry. Although many companies are increasingly focusing on the construction of management and enterprise systems, the long-term accumulation of bad winds still takes a long time. Third, companies can not keep up with the development of the times in terms of innovation awareness, innovation ability and intellectual property protection. On the one hand, due to the relatively high profit of the market, the enterprises pay more attention to profit in the development process and have insufficient investment in resources. Emphasis has led to a lack of innovation capacity of enterprises and thus to a large extent weakened Innovative products, leading to new products can easily be imitated by other companies. On the other hand, many domestic companies do not pay enough attention to the protection of intellectual property rights, and they do not realize the strategic significance of intellectual property rights to enterprises. As a result, the market competitiveness of new products is difficult to maintain for a long time, and they are often imitated by their peers in the short term. Over the past few years, as companies have suffered more and more losses, their understanding has gradually deepened. The protection of intellectual property rights has also become the focus of attention of industry and business enterprises.

At present, the development of the video surveillance display device market has fallen into a vicious circle of low-quality, low-price competition. Product homogeneity has intensified the internal competition of the entire industry, and low-cost strategies have become the only competitive means for companies that lack core competitive advantages. The profit space of enterprises has been declining, which has led to a continuous decline in the sales volume of many companies, which has led companies to continue to increase their cost control efforts, reduce R&D expenses, and make it possible to invest more resources in research and development of new technologies and new products. A vicious cycle. According to incomplete statistics, the number of companies investing more than 10 million yuan in technology research and development each year in domestic security companies is very small, and it is still less than one-thousandth of the total number of security companies. The reduction in R&D investment of enterprises will inevitably lead to product innovation. The decline in capacity and the long development cycle of new products have led companies to fall into a vicious cycle of “low quality, low price, and low quality”, making it difficult for a large number of companies to establish their core competitiveness.

For a long time, the domestic video surveillance display market has been developing along the imitation route. Compared with imported security products, national brands generally lack differentiated and innovative products, making enterprises always in an unfavorable situation in competition and lacking overall competitive advantages. . Although the domestic low-cost competition strategy has achieved a certain market share for local companies in a short period of time, the long-term market competition means that the vitality of low-price competition is far lower than that of high-end technology applications. In this context, , Local monitoring shows that if the brand has been pursuing low-price competition, the gap with leading companies will continue to increase.

three. The development trend of the video surveillance display device market Compared with the previous generations of video surveillance systems, there is a fundamental difference in intelligent video surveillance display technology. It is no longer simply to complete the processing, transmission, control, and storage of video signals. The main reason is that the intelligent integrated management system based on IP network has the characteristics of intelligent analysis on the basis of providing control, transmission and storage. The intelligent video surveillance display technology is based on the network. The front end uses the network camera, and the middle part is all digital video transmission, playback, and finally stored in a compressed format, supplemented by intelligent and practical image analysis, and integrates the alarm system and the security system. One using platform. This kind of intelligent video surveillance display technology can be said to be a technology ** of the entire video surveillance industry, and it has quickly received close attention from security companies and end users. At present, intelligent video surveillance display technology has been widely used in various aspects such as multimedia video dispatching and commanding, online video surveillance, multimedia webcasting, coal industry, and telemedicine.

Intelligent video surveillance display technology consists of front-end information collection devices, digital transmission systems, and network intelligence monitoring management platforms. Although the previous video surveillance system basically implemented the transmission from analog to digital until it supported the IP network, the front-end equipment has a single function and the management system is relatively simple. It is difficult to meet the ever-expanding and increasingly complex functional requirements of the current surveillance network. In this context, intelligent video surveillance display technology emerged as a result. Its characteristics are mainly reflected in the digitization, networking, intelligence, systematization and ultra-large-scale networking capabilities in multimedia applications.

Intelligent video surveillance display technology is based on common network video surveillance. In addition to the advantages of pre-video surveillance systems, it also has the following advantages: First, automatic weather monitoring, intelligent analysis system supports 24*7 continuous monitoring, Therefore, whenever an intrusion event occurs, it can react quickly, appropriately and effectively, completely changing the situation in the past by relying on monitoring personnel to continuously monitor and analyze the monitoring picture, but by embedding in the front-end device (webcam). Or, the intelligent video analysis module in the display terminal continuously analyzes and warns the monitored images. Second, it is an accurate alarm. The intelligent integrated management system integrates powerful image processing capabilities and runs advanced intelligent algorithms with intelligent analysis and early warning. The function allows the monitoring personnel to more accurately determine the characteristics and nature of the security**, which can effectively reduce false positives and false negatives, reduce the amount of useless and erroneous data, and improve work efficiency. Third, rapid response speed in society. An era of frequent terrorist attacks, quickly and effectively Detection of abandoned objects is more important than ever. Intelligent video surveillance display technology has solved this problem very well. It can analyze people or things that have entered the scene and send relevant data to monitoring personnel. It can not only detect regional damage, but also It can also automatically detect intrusion-prohibited areas. At the same time, it is also possible to specify the direction of movement of the object. When someone moves in an abnormal direction in a demarcated area, an automatic alarm is issued so that an early warning can be made before the occurrence of a safety alarm, and the monitoring personnel are notified to make preparations in advance. In addition, it is also possible to define corresponding countermeasures to be taken in the event of a specific security situation, so that the monitoring personnel can accurately execute the predetermined process steps, effectively preventing delays caused by human factors in the confusion, and greatly improving The fourth is to make full use of video resources and apply video resources to other areas, such as advanced hotel or corporate monitoring systems, to automatically identify the characteristics of advanced customers, and notify customer service personnel to prepare for services in a timely manner. When someone on the subway or in the crowd accidentally falls, notify the relevant person in time to provide assistance. In addition, intelligent video systems can also help the traffic department conduct traffic statistics, vehicle inspections, and so on.

Judging from the current demand for video surveillance and display equipment, with the ever-increasing number of terrorist attacks, smart video surveillance display technology is increasingly attracting the attention of the government and people, and the demand is constantly rising. In general, overseas smart video surveillance applications have been transformed into large-scale application phases, and the smart video surveillance display market has slowly begun to form a complete industry. While China currently lacks its own brand in intelligent video surveillance products, there are obvious defects in product development and marketing. Most domestic video surveillance manufacturers and promotion companies are still in the non-intelligent category, and intelligent video surveillance display technology still remains The concept of network video surveillance does not have the characteristics of intelligent video surveillance.

IV. Conclusion In conclusion, intelligent video surveillance display technology has become an inevitable trend in the development of video surveillance technology and is a new and challenging research direction in the security industry. The intelligent video surveillance system has more powerful intelligent analysis and image processing capabilities than previous network video surveillance devices, which can provide users with more intelligent video analysis and advance warning functions, which can greatly improve the efficiency of video surveillance and can maximize the The extent to which the video resources are used.
