With TD-SCDMA in eight cities in the country of testing and trial commercial society, marks the beginning of 3G era. The 3G wireless broadband to open the Internet age , will also bring significant innovations in the communications industry, security industry is no exception. 3G wireless monitoring is a typical example.The advantages of mobile video surveillance
October 2009, Jinan City has more than 1,700 buses have installed the 3G video surveillance system, public transportation command center inside the bus at any time monitoring the situation, dispatchers can at any time to summarize the operation of the vehicle, timely scheduling. In addition, bus stops through the dispatch center electron can be the location of vehicles on the bus lines and other information displayed to the passengers are waiting.
As computer security video surveillance technology, coding and decoding, network transmission technology, has gone through three stages of rapid development, the current is moving digital, intelligent, IP, network sustainable development. At the same time video surveillance with other technology, has produced many new applications, which helps to meet the different needs of users video surveillance industry. Especially with the wireless video monitoring wireless broadband networks, third-generation network communication based on wireless video applications concern. When the control and monitoring centers scattered and far away, or control of the image is not fixed (such as taxi, bus, etc.), wireless transmission means based on a variety of mobile video surveillance has irreplaceable advantages.
First, the wireless monitoring control points can be achieved everywhere, whether in the mountains or on a temporary site, not the physical line limit. Secondly, visitors anytime, anywhere, through the network, regardless of where can watch. Car radio set control, equipped with a network camera in the car, through the 3G signal transmission, we can watch real-time traffic, while front-end device can also be equipped with GPS module, you can know where the car ran. Wireless monitoring and control application mainly divided into two parts, one fixed location, such as zero or construction sites where the environment is relatively poor, due to wiring or wiring can not be too costly and wireless monitoring. Another is a mobile surveillance. Such as police emergency command and patrol. And bus, taxi, etc. These are the front-end monitor applications. More extensive back-end applications, visitors want to watch anytime, anywhere in the browser, for example through mobile phones, anytime, anywhere remote monitoring.
3G communications and video Surveillance Equipment to the fusion, the primary problem is the security monitoring products and solutions for integration with 3G technology. From security equipment vendors and solution providers point of view, the traditional security manufacturers is basically dominated by SMEs, the technology and engineering weaker than the lack of communications experience and ability to meet the 3G technology to be developed requirements of security products, which face some technical challenges. Its mainly in the following two aspects:
Device-side interface, the integration of 3G communication
3G devices based on the IP network as a transmission interface arrangement, the specific implementation, there are two ways: one is through 3G 3G transmission bridge as a bridge, similar to the current market, video servers and network cameras via GPRS and CDMA mobile network bridge to access The GPRS or CDMA networks. Another bridge on the security equipment and integrate 3G, such as network cameras and video servers and network transmission module integrated with 3G, as 3G-based transmission of encoded products. Monitoring products from the mass popularity of 3G applications, product installation, use of cost point of view, security equipment and the integration of 3G communication interface is an inevitable trend , which requires manufacturers of security equipment must have a 3G interface and corresponding protocol development capabilities.
The integration of 3G mobile monitoring terminals
One of the advantages and 3G network monitoring feature is available through 3G mobile monitoring terminal to achieve anytime, anywhere mobile video surveillance and control of the "mobile monitor" feature. This requires video surveillance manufacturers have the capability to develop two: one needs to provide at the product level standards such as 3GPP mobile streaming media format, providing 3G handset for 3G mobile terminals, or other playback MPEG-4 or H.264 standard video codec format, providing for 3G mobile broadband (384Kbps or less) of the outstanding characteristics of streams. On the other hand, you also need to provide carrier-class level in the system, video surveillance platform, 3G service component and other system-level products. Only a comprehensive systems solutions and operations to jointly build a new business system for mobile surveillance.
How to promote the development of the wireless monitor?
As for the new biology, 3G networks are not the way the construction of smooth, even though carriers are planning to invest enough money, but the actual network construction problems encountered during construction is inevitable. Nevertheless, we can not deny the prospect of 3G mobile video surveillance, in the 3G market, the case is not yet mature, the current development of wireless video monitoring business to do well at the government level and corporate level work.
Government's terms, good supervision and promoting the health of collaborative video industry specification development, clean environment for online video, and resources to achieve optimal reorganization of survival of the fittest, refine specifications; have to rely on technical support, such as more rapid and accurate legal standards that , labels, there's a short description of bad video content; in the network video management on like pluralism, complex cases, the video should be accurately defined the requirements and scope. Establish and improve relevant laws enacted to regulate people the legitimate use of wireless video surveillance, to protect people privacy and business interests.
For the corporate level, need to increase research and development efforts required to enhance the video performance. Should be to enhance the performance of the U.S. R & D direction video, China's 3G mobile terminal is a TD - SCDMA standard, WCDMA's CDMA business, and so the coexistence of multiple standards and open it with a strong U.S. chip compatibility and openness. Operators and terminal manufacturers to chip factory in close cooperation to meet various customer groups need to provide video surveillance experience, and promote greater development of the business; operators have to use full-service advantages, integration of fixed and mobile broadband resources complement each other, tied for the satisfaction of the customer base to provide video monitoring services; also use price leverage, to exercise reasonable business strategy and profit sharing, quick start wireless video surveillance operations, in order to form a climate as much as possible, so that the telecommunications industry in the boost play a role in boosting the economy.
I believe that with the development of 3G technology and the business continues to spread, the global network coverage and mobile video Surveillance Equipment become more sophisticated and perfect relevant laws and regulations enacted, mobile video surveillance system will usher in a broad market.
