The security issue in urban transit system has been widely considered as the common matters in mass transition system. The safe urban transit system is highly demanded because of the vast number of daily passengers, and providing safety is one of the most challenging projects. The authors implemented a field model for integrated security system at subway stations and demonstrated its performance. This system consists of cameras, sensor networks and central monitoring software. They described the smart camera functionality in more detail. The proposed smart camera includes video analytics, video encoder and the server modules that transmit video and audio information. The video analytic functions in the system range from enter detection to crowdedness estimation, or fire detection.
