It is transmitted to the user monitoring center through wireless networks such as CDMA20001X to achieve the purpose of remote monitoring and emergency command. What the car video server requires dual -code flow at the same time, including local independent video code flow and network passage flow.

　　Users need to extract video surveillance data. There are two ways: one is to remotely retrieved through EV-DO (CDMA20001X, Wi-Fi) through the car terminal USB port.
