Abstract: The present invention discloses a smart watch, including a housing with a mounting cavity, a top cover that covers the housing, a movement in the mounting cavity, a watch dial for displaying time, a light emitting module, a shake sensing module, a tap sensing module, and an audio player. The light emitting module is configured to be turned on when the shake sensing module senses that the smart watch is shaken and turned off when the tap sensing module senses that the smart watch is tapped. The audio player is configured to be started when the smart watch is tapped or shaken. According to the present invention, when needing to turn on the light emitting module, a user only needs to shake the smart watch worn on his/her wrist, and when needing to turn off the light emitting module, the user only needs to tap the smart watch with his/her hand. Compared with the way of turning on the light emitting module by pressing a physical button, the smart watch is simpler and more convenient in operation.

Abstract: 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.
