Who hindered the development of network video surveillance?
With the development of science and technology, IT technology has penetrated into the security industry, and network and digital have become a hot topic in the industry. Under the background of this era, network video surveillance technology moves from science and technology laboratory to large public building.
Network video monitoring for remote monitoring, monitoring method is more flexible, video monitor based on network break through the limits of time and place, eliminating the traditional wiring and line maintenance costs, reduce the monitoring cost; user authorization, can at any time according to need to monitor implementation of plug, that is, i.e. see. The network camera has many flexible characteristics and powerful networking function in the performance, and becomes the topic that everybody talks about in a short time.
Many optimists predict that within two years the digital camera will replace analog camera, analog monitoring system will replace the analog camera network video monitoring system, a large number of production equipment in the industry and enterprises and supporting will perish. In order to keep pace with the development of the times, many production enterprises are scrambling to join the production team of digital cameras.
However, in a burst of applause, the development prospect of network video monitoring market is not as good as expected. Some industry engineering personnel security revealed that the company has built a number of cities video surveillance alarm project. But so far, there has been no real city network video surveillance system, most of which are network monitoring of a community or a building. Now, it is difficult to find a completely digital network video surveillance system in the city.
Shenzhen Asia Gauss science and Technology Co., Ltd. General Manager Yao Wenzhi estimates, the domestic use of network video surveillance equipment and software projects less than 10% of the monitoring class, the proportion of foreign countries may be higher. Now, the enthusiasm of the domestic users for network video surveillance system is not high, and the traditional monitoring equipment occupies half of the monitoring market. The development of the network camera product market is not smooth sailing.
The general manager Yao described the influence of network bandwidth on the network monitoring with a vivid example: a high-performance sports car, walking on the highway, the speed can reach 300 kilometers per hour, if the car to walk on the rough road, its speed immediately dropped to 120 kilometers per hour. At this point, the performance advantage of the sports car simply can not be played out. There are many similarities between the network monitoring system and the sports car route. Network monitoring is not an independent use, need to match the "highway", this highway is network bandwidth. At present, the China Telecom operators to provide network bandwidth is 2 MHz, in the WAN, a camera to the bandwidth is 2 MHz, so the bandwidth of video conference even dozens of road network conference camera general business can not meet, not to mention the city network video monitoring system of large scale. The domestic network bandwidth can not satisfy the demand of super large amount of video information transmission. In this case, the network video surveillance system has lost its place and become a flashy display".
The industry have the same view of Wang Qiang is not alone, the network infrastructure is relatively weak in China, the broadband network and not popular in the country, especially inland city and remote areas, the Internet has no access to the local people, very little of the network monitoring known; and in many areas of the popularity of the network bandwidth, delay phenomenon obviously, a lot of bandwidth can not meet the requirement of audio and video signal transmission with large flow, affect the final effect of monitoring.
In the traditional network encountered bottlenecks when the development, many people in the industry will be pinned on another transmission medium - optical fiber. Fiber and copper compared to no loss speed, the speed is 20 times more likely than copper broadband. At present, China is carrying out the "FTTH project, can separate the optical fiber directly connected to the user's home, which is equivalent to the user opens a separate highway, even people of the same area are online, it will not affect the speed. Even with a larger transmission advantage, industry experts are not optimistic about this new data transmission channel". At present, the domestic fiber to the home is still in the pilot phase, Guangzhou, Shenzhen and other first-tier cities far from the full realization of the optical fiber to the home, the Midwest popularity is a distant thing, the network video monitoring system when entering the public view has become a distant thing.
In addition to bandwidth, cost is another major factor that restricts the development of network video surveillance. The network video surveillance technology appears time is not long, many systems and products have high technology content, and the cost is much higher than the analog monitoring and digital analog monitoring equipment. I found in the survey, most of the respondents are now limited bandwidth, in the choice of monitoring products, or tend to choose the traditional analog, analog, hybrid monitoring device. Network monitoring products in the short term is difficult to obtain consumer recognition, occupy the mainstream of surveillance video market.
Some industry analysts believe that telecom operators launched a series of broadband fiber optic reconstruction project, contributed to the upgrading of network hardware facilities, for the network video surveillance industry is a good news. Network video surveillance will also be rapidly spread over 3 years ~5 years. However, there are some experts believe that the transformation of optical fiber is completed as scheduled, the user's optical fiber use cost is how much, the telecommunications sector did not give
