Advantages of Mobile Video Surveillance With the social testing and trial commercialization of TD-SCDMA in eight cities across the country, China has entered the 3G era. The era of 3G-enabled wireless broadband networks will also bring about major innovations in the entire communications industry, and the security industry is no exception. 3G wireless monitoring is a typical example.
In Jinan, more than 1,700 buses have installed 3G video monitoring systems. The bus command center monitors the situation within the bus at any time. The dispatcher can summarize the operation of the vehicle at any time and make timely dispatch. In addition, the bus electronic station card can display information such as the location of the vehicle on the bus line through the dispatch center to the waiting passengers.
With the development of computer, codec, and network transmission technology, security video surveillance technology has experienced three phases of leap development, and is currently moving towards digital, intelligent, IP, and network development. At the same time, video surveillance is combined with other technologies, resulting in many new applications. This helps meet the needs of video surveillance users in different industries. In particular, with the development of wireless broadband networks, wireless video surveillance based on third-generation network communications has received much attention. When the monitoring is dispersed and distant from the monitoring center, or when the monitored objects are not fixed (such as taxis, buses, etc.), mobile video surveillance based on multiple wireless transmission methods has irreplaceable advantages.
First of all, wireless monitoring can realize the ubiquity of monitoring points, whether it is in the mountains or on temporary sites, and is not limited by physical lines. Second, visitors can watch anywhere, anytime, anywhere through the Internet. The vehicle is equipped with a wireless surveillance system. In the car, a network camera is installed. Through the 3G signal transmission, we can watch the road conditions in real time. At the same time, the front-end device can also be equipped with a GPS module and can also know where the car is going. Wireless monitoring applications are mainly divided into two aspects. First, fixed locations, such as zero-hour construction sites or relatively harsh environments, use wireless monitoring due to the inability to wire or the wiring costs are too high. The other is mobile monitoring. Such as public security emergency command, patrols. And bus, taxi monitoring, etc. These are front-end applications. The back-end applications are more extensive, and visitors hope to browse and watch anytime, anywhere. For example, remote monitoring can be realized at any time and anywhere through mobile phones.
The combination of 3G and the security industry will greatly expand the application of 3G and will also bring profound changes to the security industry. As the 3G network bandwidth is increased, it can provide clearer and smoother video transmission than existing CDMA and GPRS wireless networks. It makes the original video transmission effect due to bandwidth limitations unsatisfactory, and can not apply the wireless monitoring technology requirements. Also became suitable for security services. This improvement in service capabilities due to bandwidth changes is the biggest advantage of 3G and will directly promote the wider market application of various 3G wireless surveillance.
Wireless surveillance raises privacy concerns Faced with wireless monitoring, many people expressed concern. When interviewed by Professor Chen Long, a researcher at the Chinese Academy of Sciences Automation, the Qianjia.com reporter stated that due to technical immaturity and imperfections in the system, wireless surveillance is only As an aid, it is impossible to play the leading role.
Professor Chen Long said: "3G is now called louder, 3G is actually a wireless transmission, it is a means of communication, although monitoring can be done everywhere, but the monitoring is confidential and private. Borrowing Bill Gates's "Internet will be everywhere" famous quote, I personally think that "in the public occasions that do not involve personal privacy, video surveillance should be everywhere." Future public security, social security, school security, prison security should be strengthened, now Safe cities are just to ensure public safety.3G monitoring has a lot of worries, it is a supplementary and auxiliary means for cable monitoring, and it cannot be used as a primary means.First, resources are limited, and second, many hidden problems, For example, it is illegally applied to invade the privacy of others, so 3G applications will cause harm, and 3G monitoring applications need to be strictly regulated.From the current point of view, 3G monitoring technology, the current bandwidth is not enough, there are delays, jitter and other phenomena, the technology is still Very immature, it is impossible to play the protagonist."
3G Brings New Challenges to Vendors 3G communications must be integrated with video surveillance. The first and foremost solution is the integration of security surveillance products and overall solutions with 3G technologies. From the perspective of security equipment suppliers and solution providers, traditional security manufacturers are mainly based on small and medium-sized enterprises. Their technical and engineering strength is weak, and they lack the experience and capabilities in communications. Therefore, it is necessary to develop 3G-compliant technologies. The required security products face certain technical challenges. Its main performance in the following two aspects:
The integration of 3G communication interfaces on the equipment side relies on 3G networks as the IP transmission interface for the equipment. There are two specific implementations: one is through 3G bridges as a bridge for 3G transmission, similar to the current market in which video servers and network cameras pass GPRS and CDMA bridges to access mobile GPRS or CDMA networks. The other is to integrate security equipment and 3G bridges, for example, to integrate the network video server and network camera with the 3G transmission module as a coded product based on 3G transmission. From the point of large-scale popularization of 3G monitoring products, product installation, and use cost, the integration of security equipment and 3G communication interfaces is an inevitable trend. This requires that security equipment manufacturers must have the corresponding development capabilities of 3G interfaces and communication protocols.
3G mobile monitoring terminal's integrated 3G network monitoring One advantage and feature is that it can use mobile 3G mobile monitoring terminals to achieve mobile monitoring and control of mobile surveillance at any time and anywhere. This requires that video surveillance vendors have two development capabilities: On the one hand, standard 3GPP and other mobile streaming media formats are required at the product level to provide standard MPEG-4 or H for 3G mobile phones or other 3G mobile terminals. The 264 video codec format provides excellent bitstream characteristics for 3G mobile bandwidth (below 384Kbps). On the other hand, system-level products such as carrier-class video surveillance platforms and 3G service components are also needed at the system level. Only comprehensive system solutions can work with operators to build a new mobile monitoring business system.
How to promote the development of wireless monitoring?
As a new creature, the current construction of 3G networks is not always smooth. Although operators are planning to invest sufficient funds, the problems encountered in the construction of actual networks are also inevitable. In spite of this, we cannot deny the prospect of 3G mobile video surveillance. Under the circumstance that the 3G market is still immature, the current development of wireless video surveillance services must be done at the government level and at the enterprise level.
On the government level, do a good job of supervision to promote the development of healthy and coordinated video industry standards, purify the network video environment, achieve the survival of the fittest and optimize the resources, reorganize and refine the specifications; rely on technical support, such as more quickly and accurately find legal standards , Labels, description of a short piece of bad video content; In the case of network video management complex, complex, the video should have accurate provisions and scope. Establish and improve relevant laws and regulations, regulate people's legal use of wireless video surveillance, protect people's privacy and the interests of enterprises.
For the enterprise level, more research and development efforts are needed and video performance needs to be improved. To improve the U.S. video performance as a research and development direction, China's 3G mobile terminal is a TD-SCDMA standard, and WCDMA's CDMA service and other standards coexist. The open American chip has strong compatibility and openness. Operators should work closely with terminal manufacturers and chip makers to provide video surveillance experience that meets the needs of various customer groups and promote greater development of the business. Operators also need to take advantage of full-service operations to integrate fixed-line and mobile broadband resources. , complement each other, bundle up, provide satisfactory video surveillance services for each customer group; also use price levers, implement reasonable business strategies, quickly start wireless video surveillance business, in order to form the climate as far as possible, so that the telecommunications industry is boosting The economy plays a boosting role.
It is believed that with the development of 3G technology and the continuous popularization of services, the global signal coverage of mobile networks and the maturity of mobile video surveillance systems and the development of relevant regulations will be improved. Mobile video surveillance systems will surely usher in a vast market.
