The SafeDrive MiniDVR is an event-based mobile DVR that installs directly to the windshield and incorporates both a forward-facing road-view camera and a rear-facing cabin-view camera to record video, audio, and metadata to a high capacity and economical CompactFlash card. It has an internal battery backup feature that enables recording to continue until the car battery dies. Video is automatically recorded when speeding, driving erratically, when a crash occurs, or when triggered manually. Safety Vision. 800-880-8855.
