To provide a technique of recording video data appropriately.SOLUTION: A drive recorder 3 transmits to a server device 4, a moving image file showing a state in the periphery of a vehicle 2 when large acceleration is generated. The server device 4 determines whether or not to designate prohibition of overwriting with respect to the moving image file showing the periphery of the vehicle 2 based on the moving image file when an event occurs. Then, the drive recorder 3 designates the prohibition of overwriting with respect to video data at, or before and after the occurrence of the event based on the thus obtained determination result and counts a number of the video data.SELECTED DRAWING: Figure 2

    【課題】映像データを適切に記録する技術を提供する。【解決手段】ドライブレコーダ3は、大きな加速度の発生時における車両2周辺の状況を示す動画ファイルをサーバ装置4に送信する。サーバ装置4は、動画ファイルに基づいてイベント発生時の車両2周辺を示す動画ファイルに対し、上書禁止を指定するか否かを判定する。そして、かかる判定結果に基づき、ドライブレコーダ3は、イベント発生時又は発生前後の映像データに対して上書禁止を指定するとともに、その数をカウントする。【選択図】図2
