In recent years, along with the comprehensive upgrade of video surveillance technology and the development of network technology and the continuous expansion of application requirements, the security monitoring market has grown rapidly and is moving toward digitization. Digitalization, networking, intelligence and high-definition have become Security monitoring market development inevitably. According to research data, it is expected that by 2011, the video surveillance market share will reach about 3.8 billion US dollars.
With the rapid development of the market and application of network video surveillance, the demand has become increasingly prosperous. This has created a situation in which a large number of brand manufacturers have marched into the security video surveillance market. In order to ensure the interconnection, interoperability and effective transmission between products of different manufacturers in the monitoring system, interface standards for various devices must be formulated first to prevent users from being “stuck†by the products of a certain vendor. At present, China's surveillance market is in a state of no standard, and the market is basically monopolized by several big brand manufacturers.
We know that a set of digital security monitoring systems include video encoders, storage devices, network devices, and monitoring software in addition to the front-end cameras. In many products, it is necessary to ensure the interconnection and interoperability of products from different vendors. At the same time, to avoid users being “tightened†by the products of a certain manufacturer, the formulation of relevant standards is particularly important. Therefore, formulating unified standards for various devices has become a common concern among manufacturers, integrators, and users.
Nowadays, more and more security vendors have launched their own high-definition surveillance camera products. However, because there is no uniform standard for “HD†in the industry, everyone has a different understanding of “HD†standards, which directly leads to many different Types of HD surveillance camera products. Different standards, the effect of "HD" is naturally not the same, which brings a certain degree of confusion to the consumer market. In particular, with the development of network monitoring, the standardization of network cameras has become more and more important. The purpose of standardization is to enable products from different vendors to be interconnected and interoperable, so that customers can truly enjoy the flexibility and efficiency brought about by network monitoring. The consumer market runs counter to it.
In the case of standards that have not been unified yet, vendors have to work hard to be compatible. As the industry leader, Sony will also be guilty of not having uniform industry standards. Mr. Wen Jun, Sony's security product manager, said at a media exchange meeting that there is no unified standard and each manufacturer does its own job. In order to expand the use of the product, Sony had to make the interface compatible with multiple standards. It is not easy for a complex monitoring industry to be fully compatible, and standard conflicts are inevitable.
At present, there are many standards-related organizations in the field of security monitoring. Some are regional, some are governmental, and some are standard organizations under a large project. However, they are not widely recognized and are not binding. . In contrast, some of the standards sponsored by important vendors that occupy the mainstream of the video surveillance market are supported by more and more security vendors, integrators, and distributors and have become more influential in the security industry. Industry Standard. This makes the development of the market appear polarized. Whoever has the money and who will build it will have the final say. Stronger people are stronger, weaker people are weaker, and even die. For SMEs, they are more likely to expect the introduction of binding related standards.
Officials from the Ministry of Information Industry have also stated that at present, the monitoring market is still dominated by foreign brands. After domestic companies enter the surveillance field, they face the issue of patent fees and are faced with difficulties in development. In order to promote the development of ethnic minority enterprises, China's video surveillance industry needs to establish a video surveillance industry standard with independent intellectual property rights.
However, although the China Communications Standards Association has published a series of standards for the "Telecommunication Network Video Surveillance System" based on the research report, the National Security Alert System Standardization Technical Committee has also formulated "Video Security Monitoring" for the new features of the current surveillance technology. System" series of standards. However, people in the industry pointed out that these standards will not be able to meet the needs of users in the short term, and the market will still be in a state without standards.
Professor Chen Long, a researcher at the Institute of Automation at the Chinese Academy of Sciences and an expert on the Security Standardization Committee, also mentioned at the 10th China International Building Intelligence Summit Security Industry Summit: “High-definition is the focus of attention in the field of video surveillance. First of all, the unification of standards This is the most vexing problem.Generally speaking, high-definition means that the physical resolution is above 720P, and above 720 is used as high-definition.There are two standards for SD in the world, one is 720P or 1080I or more. There is also interlaced scanning.There are no standards in our country. We use 720P and 1080I. Network video surveillance generally includes three parts: front-end, transmission, and back-end storage management. There should be uniform standards for the product and application of each part. Currently, there are enterprise standards, industry standards, and international standards on the market, most of which are recommendations, and there is no national coercive force.When selecting a standard, manufacturers often choose their own standards to protect their own vested interests. On the same type of product, when used in other card subsystems There will be incompatibility, so that the user is a big headache. "
When visiting a number of security companies in Shenzhen, Qianjia.com reporter found that under normal circumstances, only the front end does not do the back end or only the back end does not do the front end of the manufacturers, very inclined to the emergence of the standard, because once there is a standard. Can promote their sales. The front-end and back-end manufacturers are not in a hurry, and do not even want to set up a standard because they can use their own comprehensive advantages. It is precisely the size and strength of the front-end and back-end manufacturers that are more powerful and occupy a large amount of market share. Standards organizations must absorb this part of the company, otherwise it becomes a short standard that no-one would ignore. In addition to the need to compress video when transmitting video over networks, the compression algorithms of companies are different, which makes it difficult to form network video standards.
In short, due to the current chaotic standards and the lack of unified and binding standards, the market has become chaotic. The incompatibility of various standards makes it impossible for all parts of the interface to be docked. It has become a technical problem that often needs to be faced in the construction of monitoring projects, and it may even cause the entire project to stagnate. At the same time, due to the incompatibility between products, the upgrade and maintenance of the system have been greatly affected, resulting in the waste of a lot of resources. Therefore, judging from the sound development of the entire industry and promoting the popularization and application of high-definition surveillance, it is of great significance to formulate a binding industry standard.
