2011 HD security monitoring of the security industry continues to develop in an all-round way

As the national economy maintains a good momentum of development, the people’s living water is steadily increasing, and public safety, production safety, and property safety are receiving more and more attention, thus making video surveillance featuring video information more extensive. Applied in various industry fields. The traditional monitoring mode can no longer meet the needs of security protection in all walks of life, but the network video surveillance system with high-definition features has become a new application trend.

In 2010, it was recognized as the “high-definition first year” in the security industry. Major security manufacturers have launched HD series products. HD products have become the “new darling” of security exhibitions across the country. In 2011, with the continuous development of high-definition technology, full HD network cameras ranging from 1.3 million, 2 million, and 5 million front-ends to high-definition codec cards, high-definition storage, high-definition displays, and high-definition management platforms were introduced. It entered the application implementation stage. Looking at the national security exhibition in 2011, HD surveillance has undoubtedly become a "hot spot" in the security market. The well-known domestic security manufacturers in the promotion of high-definition full range of products, but also actively promoted the case has been applied high-definition monitoring, which marks the application of high-definition monitoring rise in the eyes of many people. In the next few years, the high-definition surveillance market will further develop rapidly. In the near future, it can be predicted that high-definition surveillance will become the mainstream of the market.

From the concept to the application of high-definition has entered the initial stage in the field of security monitoring, high-definition from the concept to the application does not take a long time, this is because of the results of multi-demand driven. For users, the traditional SD monitoring system only records events and it is difficult to provide more key details. As a result, the role and effect of monitoring applications cannot be improved. Therefore, new technologies need to be developed to improve. For technology and product development, there is little room for SD technology to continue to develop. For the market, it is also urgently needed new products to stimulate growth, and high-definition exactly meets the needs of many parties and becomes the current and future development direction. How to see a person's facial features in a bustling downtown; how to clearly see the vehicle license plate on the fast-moving roads while clearly seeing the facial features of the passengers and drivers, these demands promote the development of high-definition surveillance.

Driven by the drive to monitor the Internet trend and market demand, HD applications have entered the initial stage in 2010. Million HD products have also been gradually accepted by more and more users. At present, there have been many cases of successful applications. For example, the Guangzhou Asian Games and the Shanghai World Expo have all adopted HD solutions, which fully demonstrates that the market is recognized for high-definition. The overall performance of HD surveillance is accepted. Concomitant with this is that high-definition surveillance has also entered the application stage in many industries. For example, many HD video surveillance systems in the country have included high-definition surveillance systems in their planning and construction. For the moment, with Jin Sanli as an example, high-definition surveillance products have been successfully used in a number of industries such as “Safe City” projects, transportation, hospitals, finance, schools, and other networks with mature construction, creating high-definition cases that are fully favored by customers. As the technology continues to mature, it is believed that the high-definition surveillance will be fully applied with its powerful picture quality advantages to meet the strong market demand for high-definition surveillance.

High-definition surveillance requires a complete solution For the high-definition HD, major players in the industry have launched their own high-definition products. However, for high-definition surveillance, can only rely on a single high-definition device to get the overall situation? We can first look at the traditional video surveillance system framework: whether it is analog surveillance or digital surveillance or network monitoring, they are all from the center of surveillance cameras, NVR/DVR/management platform management equipment, display equipment, and transmission cables The most basic systems are indispensable. Therefore, all parts of the high-definition monitoring system must be "cooperated with the times" to provide a complete solution covering the front-end, transmission, management center and back-end hardware and software equipment.

At present, many monitoring companies have begun to launch a complete high-definition monitoring solution and corresponding equipment, including all high-definition product systems from front to back. From the perspective of the resolution of the front-end camera, the typical representative is a 1.3-megapixel, 2-megapixel CCD, and a 3-megapixel, 5-megapixel CMOS high-definition camera capable of full-real-time monitoring, ie, 25fps high-definition monitoring. Industry-leading pure digital high-definition camera, it is different from the general network camera: First, compression, network cameras generally use MPEG-4 or H. The 264 standard encodes and compresses, but the digital camera does not necessarily compress and output the digital image stream directly; 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 the optical fiber or Digital interfaces such as HD-SDI transmit digital video streams. Of course, this is only part of the HD surveillance system, and it also requires high-definition encoding and high-definition stream transmission, or direct transmission of uncompressed high-definition digital streams, exchange control of high-definition digital signals, and high-definition stream access And HD display. It is particularly important that, as the "brain" 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, management signaling, and so on. Only in this way can the high-definition monitoring system be able to successfully complete the "high-definition monitoring" task.

High-definition surveillance showed an outbreak trend in 2011. As a high-definition promotion year in 2011, video surveillance vendors are aware that there are three major priorities in promoting high-definition: full-line product supply, the industry's overall solution, and the application environment.

The continuous application of the latest technology to create an efficient and comprehensive security monitoring system, which is required by the market for social security protection and business application of various industries, is also the direction of the security industry's continuous efforts. Under the dual promotion of technology and market, high-definition monitoring moves from concept to practical application. Because high-definition monitoring is a complete system composed of many parts such as front-end and back-end. Therefore, the gradual development of high-definition applications will also drive all aspects of the video surveillance system into a new upgrade phase. As early as seven or eight years ago, companies already started to make full-line products. When any company develops to a certain scale, it will be a full-line product supplier. Now it can be seen that most of China's mainstream security companies have become full-line product suppliers.

Creating a dedicated solution for customers rather than a simple combination of products from various vendors is the way to develop high-definition surveillance in the future. Therefore, the collective appearance of the full range of product suppliers is a good indicator of the development of the security industry and a good example of the brand strength of the company. From the user's point of view, where is the competitiveness of the company? It should be able to provide value-added services to customers and provide value. Only solutions can do this better. Therefore, many security companies have invested in the development of solutions, which is an inevitable trend in the development of the security industry. From a technical point of view, it is HD and smart. From an application perspective, it is an industry solution. From the perspective of customer value, it is a system solution.

High-definition is an inevitable trend in the development of the security monitoring industry, and it is also an inevitable law for the development of the industry. The development of the security industry has made HD, networking, and intelligence become the technical direction that leads the development of the entire security industry. High-definition is the premise. Networking and intelligence are closely followed. They complement each other and require the cooperation of the application environment. , especially the improvement of transmission conditions.

The application of high-definition surveillance has not just started. China's video HD has already been used in many major projects such as the Beijing Olympics and Shanghai World Expo, as well as high-end projects such as finance and safe city construction. In addition, there are also high-quality applications in the field of intelligent transportation. A large number of applications, with 2 million to 5 million pixels of high-definition camera applications, have been rolled out. In 2011, HD monitoring has been applied more in a larger range. HD is an inevitable trend, and this trend is irreversible. Of course, in practical applications, there are still some obstacles to high-definition intelligence. At present, the application of high-definition is only in some industry solutions, there are some applications in some industries, in the conventional monitoring market, high-definition monitoring has not been rolled out, the main obstacle is the transmission and operating costs. At present, the transmission of IP high-definition monitoring is based on the network. At present, many conditions do not have the conditions for large-scale access to the network high-definition monitoring system. The traditional monitoring system HD access can only be transmitted through SDI. The transmission distance of this transmission method is limited, and it can only be achieved through optical fiber links. However, the high-definition of the related equipment has just started and the equipment cost is very high. For example, SDI's related testing equipment requires 300,000 to 400,000 units. If it is to develop SDI products, such testing equipment must be available. High-definition surveillance really needs to achieve a certain scale, and more companies need to invest in it. High-definition intelligence is the direction of development, but there are some technical means of implementation and promotion work to do.

In short, although the domestic high-definition surveillance market is at an initial stage, it is certainly the future trend. With the rapid development of security monitoring technology, high-definition as one of the main directions for the development of monitoring technology, combined with network technology to bring about new changes, while continuing to meet the needs of market competition, while tending to a rational and healthy development. HD surveillance is entering the public's horizon with a high profile and high demand. In the field of continuously developing monitoring technologies, high-definition surveillance will have broad prospects.
