China's wireless surveillance dominates public safety applications

It is estimated that by 2017, the global video surveillance wireless infrastructure market will grow at a compound annual growth rate (GAGR) of 17%. Global growth will lead China, with a compound annual growth rate of 28.8% in revenue during this period. The second fastest growing region is the rest of Asia (including India), which will grow by 27.9%. Mexico's CAGR is 23.1%, Brazil will grow 17.4%, and other regions of South America will grow 26.6%. In the next few years, Asia is expected to become the fastest-growing region in the world because it currently does not have any wired monitoring infrastructure, and wireless costs in the region are relatively low and security needs are increasing. Wireless monitoring explosive growth, the status quo of industrial applications?

State of the art: wireless surveillance security market explosive growth "Compared to the laying of cables, wireless infrastructure provides a relatively inexpensive solution, providing low-cost options for customers who want to establish a monitoring network," said Josh Woodhouse, an IHS video surveillance analyst. . "In areas with extensive video surveillance facilities, such as the United States or the United Kingdom, the use of video surveillance wireless infrastructure is steadily increasing. However, emerging regions lacking such infrastructure will generate the strongest growth in the world, prompting video surveillance wireless. The infrastructure market will flourish in the coming years."

As the basis for the development of the Internet of Things, the security monitoring industry will benefit from the further development of the Internet of Things technology. The digital, analog, and HD-SDI HD technologies related to this will be comprehensively improved and will give users a wealth of choices. With the improvement of the algorithm, the intelligent analysis technology will begin to enter the actual project construction, especially for image diagnosis, image retrieval and other image detection functions. Will be strengthened. In 2012, the total output value of China's security industry has reached about 325 billion yuan. Under the influence of the new policy, China's security market is expected to achieve a 30% growth rate. The applications of finance, public security, transportation, medical care, education, culture and technology, communications, energy, and production enterprises will be more extensive and in-depth, and the business opportunities in the civil security market will also show explosive growth.

The success rate of video search is more than 99%, the recognition rate of smart video is over 90%, the accuracy in daytime is over 90%, and the accuracy in nighttime is over 80%. Intelligent video surveillance has become a weapon for companies to occupy the commanding heights of the security market. At present, nearly 400 cities have applied the company's products and technologies in the construction of smart cities.

Telecommunication operators also aimed at the Internet of Things home security market, first, China Telecom launched the "Global Eye" video surveillance business, both for the industry can also be used for home security monitoring, but also launched for smart home, home Security's "3G Smart Butler" business; China Mobile is tailored specifically for home security tailored to the "livable pass" business standard, allowing users to keep mobile phones at home, magnetic door, infrared detection, gas detection and even camera Monitoring status, anti-theft alarm, video surveillance, gas alarm, fire alarm and elderly help.

“The wireless monitoring solution has achieved 3G wireless surveillance output standard definition images in terms of image storage and traffic. Users can select standard definition or high definition according to their definition of image definition, and the image resolution also varies from QVGA to 1080p.” Wei Wei, Dean of the School of Electronics and Information Engineering at the University of Science and Technology, said that supporting wireless or 3G surveillance electronic eye products will become the new darling of the market. In addition, with the forthcoming 4G era, 4G technology will gradually be applied in security products.

Technology: 4G technology makes wireless surveillance even more powerful. The impact of 4G network technology on the security industry is mainly reflected in the field of wireless video surveillance. Wireless mobile monitoring is the branch of network monitoring, and the pressure of network transmission becomes more prominent. The advent of 4G networks will apply its advantages of mobile wireless transmission to the field of mobile surveillance. Judging from the current pilot situation, 4G networks are 10 times faster than 3G networks, with download speeds of up to 100M and upload speeds of 20M. The bandwidth required for general 720P high-definition monitoring is basically between 2M and 4M. This satisfies the good demand for high-definition monitoring. If 4G networks can be widely used in China, then devices based on second- and third-generation network transmissions will gradually lose their market. In the future, under the impact of the 4G wave, the upgrade and transformation of old products in the security industry will be inevitable.

From the point of view of the security industry, network monitoring has become a major trend in the industry. However, the actual market share of network monitoring is still quite low. People in the industry believe that this is due to the fact that the domestic network environment is not mature enough. At the same time, the current high-definition surveillance trend in China has become even more obvious, many well-known monitoring companies have begun to launch more clear 700-line cameras, and some manufacturers have even begun in the industry to launch the first 10 million pixel camera. With the widespread use of these high-definition monitoring front-ends for the back-end, the transmission pressure will become even heavier. As a result, the industry is generally applauding the arrival of 4G networks. Everyone thinks that compared with 3G, 4G is mainly improved in transmission bandwidth and transmission speed, and there is also a big breakthrough in stability.

At the same time, the usage fee of the traffic is also a topic of concern to many people. Since the packages made by various operators are not the same, resulting in a high operating service fee, it also makes it difficult to promote wireless high-definition surveillance. It is understood that the 4G network adopts a gradual introduction method, and the upgrading of the technology on the basis of the original 3G will naturally reduce the cost. According to relevant sources, the cost of the future 4G network will be lower than the current 3G package fees.

In this way, if 4G networks can well solve the problems of wireless monitoring in terms of bandwidth, stability, and traffic costs, the impact on HD surveillance will be revolutionary. In other words, the development of 4G network technology will make wireless surveillance even more powerful.

Applications: Mainstream Applications of Wireless Video Surveillance Technology Thanks to the portability and flexibility of wireless surveillance, wireless surveillance applications mainly include the following types:

Unable to deploy wired monitoring application scenarios: such as transportation tools (cars, trains, ships), law enforcement management (traffic police, urban management), special escort (armed police, banks, hazardous chemicals), etc., under the conditions of mobile networks, cable networks cannot be laid and covered ;

The application scenarios that can be deployed but the cost is too high or the cost of temporary wiring may be wasted: The former, such as resource monitoring (forests, rivers, oil fields, substations, base stations, border posts, ports, scenic spots), etc., are often affected by geographical environment and work content. With restrictions, wide geographical coverage, and sparse users, the long-term work cycle for the cable monitoring circuit is very long and the maintenance cost is very high. It is even impossible to achieve the latter. The latter include temporary deployment of public security investigations, field training of troops, temporary construction sites, and temporary events. ,Exhibition Center;

Need to add monitoring application scenarios: such as homes, communities, shops, SMEs, buildings, bridges, tunnels, intersections, etc., when the second construction, it is best not to destroy the original decoration or work surface;

Emergency and personnel cannot approach the application scenarios: such as emergency command (flood, fire, emergency), flammable and explosive dangerous places, large-scale mass gatherings, important safety and security task sites, disease-infected areas, microbiological danger areas, etc., need to be shorter A complete set of monitoring network is built in time.
