{Ck}, the data of the detected image Ak is stored as it is, and the evidence images Bka, Bkb, and the transmission image C are stored.
The data of k is compressed and stored by JPEG or the like. The detected images Ak, the transmission images Ck, the evidence images Bka, and Bkb are sequentially stored from the right in a time-series manner in a ring shape, and the oldest images located at the top of the time-series images after a lapse of a predetermined time. Those exceeding the fixed amount are rewritten to the latest detected image Ak, the transmitted image Ck, the evidence images Bka, Bkb, and when an abnormality is detected by the abnormality determination unit 25 described later, the image storage unit 22 stores the image data for a predetermined time from the time of the abnormality detection. After storing, the rewriting function is automatically stopped. As a result, it is possible to store an image with excellent proof against the occurrence of an abnormal situation.
