An object of the present invention is to provide a drive recorder that can check whether the essential components of the drive recorder are functioning properly for recording of video information. More specifically, the invention provides a drive recorder which is connected to an image capturing unit that outputs data, includes an image processing circuit which receives the data and converts the received data into video information, an acceleration sensor which outputs acceleration information representing an acceleration exerted on a vehicle, and a control unit which determines that a recording condition holds when the acceleration information equals or exceeds a threshold, and records the video information onto a recording device, wherein the control unit diagnoses connections to the image processing circuit, the acceleration sensor or the image capturing unit during power-up of the drive recorder.
