  • TD-LTE to fusion 4G HD camcorder to Network

        HD monitor as a covering the front end, transmission, management, and back-end aspects of systems engineering, transmission distance due to the monitoring system, flexibility, deployment cost constraints is bound to Network. HD cameras as a front-end devices for high-definition monitor, will also to network.
        IP camera wireless transmission technology
        HD IP camera in providing people with clear visual experience, but also put forward higher requirements for network bandwidth. 720P real-time video, for example, using the standard H.264MainProfile HD IP camera compression algorithm requires at least 2Mbps to get the HD visual effects, the 1080P full real-time video need 4Mbsp. The ordinary ADSL upstream bandwidth has long been unable to meet the needs of high-definition video. With 3G, Wi-Fi, private network, wireless and wired broadband technologies mature and remote transmission of large flow of data is more convenient, which also swept away the HD network camera transmission barriers in a wide range of applications.
        Currently, in a safe city, the financial network monitoring projects 1000M bandwidth networks usually self-built fiber network or local area network. This Gigabit bandwidth resources at the front end to install the 100 road 1080P full real-time HD web camera (even per road resource 4Mbps calculation), occupied less than 50% of the total bandwidth resources; 720P transmission bandwidth can also be reduced by half. So, can effectively support the practical application of the HD IP camera.
        Wireless transmission, 3G networks has accelerated the speed of mobile Internet applications such as video telephony, mobile games in full swing. But video surveillance in the security industry, still has no substantive application. The reason for the First 3G network construction is lagging behind; two 3G tariff still too high. The face of high-definition video surveillance requirements for bandwidth, 3G skills needed. If we really want to achieve the high-definition wireless video surveillance, and also need to wait until a 4G promotion. TD-LTE emergence of for us to open the door to the 4G era of high-definition video surveillance.
        TD-LTE, TD-SCDMA Evolution to IMT-Advanced (4G standard) direction and the basis for the work, both inherited and the development of China´s independent intellectual property rights of TD-SCDMA technology, has been widespread international support. LTE peak rates accordance with the the 3GPP´s TR25.913 defined, demanding uplink 50Mbps, 100Mbps downlink. From the point of view of spectral efficiency, both uplink and downlink spectral efficiency are our current network of 3-4 times. LTE technology development has attracted the participation of different institutional norms, including the UMTS (3GSM), as well as CDMA2000 camp participation LTE becoming a 4G wireless network may in the future.
