This is a real incident happened in a office. This office is belongs to my old friend's friend. At the main entrance of the office, they installed a infra-red type CCTV to monitor who is going in and out. It also came with motion detector which any object is moving, the camera will start recording.
These two video clips were recording on the same day, it was early morning and still no body working in the office. The boss only found out this after few days later. The videos were recorded in digital format, they are not using 'video tape' to record it. If a video tape recorded repeat many times, we may see double image on the video. These video were recorded into VCD format, so there is no such thing of previous image appear on the screen.
So... What do you think?
