Abstract: A real-time mobile video reporting device installed to a motor vehicle and electrically connected to an automobile power supply includes a casing, a printed circuit board, a camera, a central processing unit, a memory, a control key and a mobile network connection module. The printed circuit board contains the camera, central processing unit, memory, control key and mobile network connection module, and the printed circuit board is disposed in the casing, such that the camera and the control key are disposed on a surface of the casing. When there is an accident, the control key may be pressed to record the scene of the accident by a video method and transmit the scene to an emergency remote reporting data center or a non-emergency remote reporting data center and car owner via a mobile wireless transmission technology, so as to report an accident quickly and prevent crime effectively.
