Bus Surveillance system is used to provide the video surveillance in the bus and the vehicle locations through GPS modem, transmitting via the router on JetBox 9300. The video stream from each IP camera shall be converted into Ethernet frames which are transmitted to JetBox 9300 which equipped with router function. Through GPS modem, the control center will receive the status inside the bus and the locations of each bus to control the traffic condition. Also, the environment inside the bus is humid, high-temp and shocked, JetBox 9300 is with wide range temp (-25~70�‹C), anti-shock/vibration and IP31 which is the best solution for bus companies.
