The video surveillance system contains a controller, a camera, a sensor, and an optical sensitization paper. The sensor and the optical sensitization paper are arranged at the same height. When an object is between the sensor and the optical sensitization paper, the sensor would send an alarm signal to the controller. The controller is to provide processing for the received signal. When it receives the alarm signal from the sensor, it triggers an alarm and sends an activation command to the camera. The camera, after receiving the activation command from the controller, starts video recording and sends the video data to the controller for showing on the display monitor, or output from the USB port, thereby preserving evidence to resolve any dispute.
