Network camera wireless transmission technology

Network camera wireless transmission technology
HD monitor as a front-end covers, transmission, management center and back-end aspects of systems engineering, control systems due to the transmission distance, flexibility, deployment cost constraints bound to network.HD IP Camera as a high-definition monitor front-end equipment, will also move towards network.
Network camera wireless transmission technology
HD network camera provides a clear visual experience to the people, but also for network bandwidth has put forward higher requirements. Real-time video to 720P for example, using the standard H.264 Main Profile compression algorithm requires at least 2Mbps HD Network Camera to get "high definition" of the visual effects, and full 1080P real time video you need 4Mbsp more. Ordinary ADSL upstream bandwidth already unable to meet the needs of high-definition video. With 3G, Wi-Fi, private network and other wireless and wireline broadband technology matures and applications, remote data transfer large flow more easily, which also swept away theHD IP Camera applications in a wide range of transmission barriers.
At present, the safe city, the financial network monitoring and other projects usually self-built fiber network or local area networks 1000M bandwidth networks. This gigabit bandwidth resources, installing 100 road in front 1080P FullHD IP Camera real time (even if 4Mbps per channel footprint calculation), occupy less than 50% of the total bandwidth resources; 720P transmission if it is used, the bandwidth can be reduced by half. This can effectively support the practical application of high-definition network camera.
Wireless transmission, 3G network speeds up mobile Internet speed, so that video telephony, mobile games and other applications in full swing. But in security video surveillance industry, still no substantive application. The reason, first 3G network construction is lagging behind; Second 3G tariffs still too high. The face of high bandwidth requirements for video surveillance, 3G is not make it. To realize high-definition wireless video surveillance, but also need to wait until the 4G promotion. Currently, TD-LTE appears, for the 4G era we opened the door to high-definition video surveillance.
TD-LTE TD-SCDMA is the IMT-Advanced (4G standard) direction and evolution based on both inherited and developed China's independent intellectual property rights TD-SCDMA technology, also received broad international support. The TR25.913 defined by 3GPP, LTE peak rates of demanding, uplink 50Mbps, down 100Mbps. From the perspective of spectrum efficiency, either upward or downward spectral efficiency are our current network of 3-4 times. LTE technology development has attracted the participation of different institutional norms, including UMTS (ie 3GSM), there CDMA2000 camp participation so that LTE 4G wireless networks gradually become a possibility.
In the Shanghai World Expo, China Mobile to build TD-LTE demonstration network's coverage Expo 5.28 square kilometers, to build a TD-LTE outdoor station 17, the realization of the nine venues indoor coverage, including seven venues in Pudong and Puxi 2 venues. TD-LTE demonstration network based on the movement of high-definition conferencing, mobile high-definition video surveillance, mobile high-definition video on demand biography, business presentations and other portable VXIS are open to the public, and have achieved good results.
