Recently, Weihai branch of China Mobile and Weihai City Transportation Bureau signed cooperative agreement of vehicle-mounted wireless video surveillance. The project is based on a high-speed mobile 4G network. In it, 4G data card is installed on the terminal in a law-enforcement vehicle and information inside data card is transferred to the server via GPRS VPN lines, docking with the transportation emergency-response command platform, to realize that traffic enforcement officers can carry out real-time monitoring, dispatching and commanding to law-enforcement vehicles, scenes of law enforcement and emergent events.
According to reports, vehicular video surveillance is that through 4G network, real-time images inside the vehicle are transmitted back to the monitoring center by vehicular monitoring devices, which facilitates unified supervision and scheduling. The system consists of a VPN dedicated line, USB wireless network card with 4G SIM card in, and the front-end monitoring device, these three parts. By front-end monitoring equipment installed on the vehicles, the images are captured, and then sent back to the surveillance server by the 4G network card through VPN wireless encrypted tunnels, which realizes remote monitoring by managing staff. Main features contains real-time video browsing, timed capture of images, audio/video storage and playback, alarm linkage and system management, etc.
At present, Weihai branch of China Mobile are providing vehicle video monitoring services for Weihai Road Transport Management Office and Weihai City Traffic Monitoring Detachment, totaling 22 law-enforcement vehicles, and in later stage, wireless video surveillance business cooperation will be realized on more than 400 long-distance passenger transport vehicles, greatly improving the convenience of traffic enforcement.
