Plug & Play Loop Recording: You never have to worry about the memory card filling up. Once full, the camera automatically records over the oldest video files in a continuous loop. Accident Protection (G-Sensor): If the camera senses a sudden impact or sharp braking, it instantly locks the current video clip. This prevents the important accident footage from being accidentally recorded over.????
