High-profile released recently, 4 g licenses, the application of the 4 g technology began to come into the mind of the more "security".According to the report, the speed of the 4 g network is ten times the 3 g network, download speed of up to 100 m, upload speed is 20 m, and can realize high quality video image transmission, will be able to meet more security user demand for network monitoring service.Thus, the advent of the era of 4 g, no doubt, will create security video surveillance application in more fields, such as in the safe city project monitoring, security monitoring, from all walks of life and networking alarm service, comprehensive security video surveillance in the hosting service etc.

      At present, as a source of huge amounts of data, the information age security video surveillance data generated a lot of information.However, the existing communication technology application in security industry are not very ideal.Of security video surveillance video streaming) has not only huge amount of data and related data packets, huge amount of information is difficult to quickly broadband transmission through the network to the back end equipment, video monitoring card resistance in the process of transmission, packet loss phenomenon is quite serious, and in terms of materials, huge video traffic, also caused the user is difficult to bear the high cost, large flow rate of the video monitoring is difficult to achieve a wide range of applications.In addition, factors such as limited bandwidth, high cost is also more or less affect the popularity of the security industry.

         For 4 g's influence on the security surveillance industry, the industry's leading enterprises Angola away technology co., LTD., said: "in the field of video surveillance, security industry, the lack of a big traffic and video surveillance network that can meet the needs of broadband data transmission environment, seriously hindered the industry forward, especially in the field of high-definition network video monitoring, video images are blocked due to transmission, image is not hd is often happened. Therefore, the issuance of the 4 g licences, is timely."

         An engineer of the company further explained that "hd video monitoring to the requirement of bandwidth, wireless real-time video at 720 p, for example, using standard h. 264 mainprofile compression algorithm of hd IP camera need at least 2 MBPS to get" hd "visual effects, full 1080 p real-time video will be expected to more than 4 MBSP, the bandwidth of the 3 g era is" overwhelmed ". The 4 g network uplink rate of 20 MBPS, descending rate can reach 100 MBPS, can effectively support the practical application of hd IP camera, striding forward drive hd wireless video surveillance industry."

        But we also should see, after all, 4 g is still in its early commercial trial operation, truly realize the wide application of 4 g still need a period of time.So, short-term hope 4 g security video surveillance transmission solution is unlikely.Can foresee, however, with the deepening of the 4 g network construction, the continuous improvement of the 4 g wireless communication technology, 4 g for security industry, especially in high definition video monitoring, data transmission, data storage, etc., will bring far-reaching influence.Can be clear that the application of the 4 g technology will drive hd network video monitoring towards a new stage, security monitoring will usher in a new development.
