a multi-video image synchronization and tamper-proof system and a method thereof

The invention relates to a multi-video image synchronization and tamper-proof system and a method thereof, the system comprising a main camera, a sub-camera and an information synchronization device.The information synchronization device comprises two information display surfaces, a main display surface and a sub display surface, and two display surfaces display synchronization information. The sub-camera lens is aimed at the products produced in the production site, each product is marked with the product code information respectively, and the sub-camera collects the code information of eachproduct; The main camera lens is aimed at the production site, the sub-camera is located in the camera range of the main camera, and the main camera records the process of collecting product information by the sub-camera. The synchronization information displayed on the two display surfaces is simultaneously collected by the main camera and the sub-camera respectively. The method is used in the multi-video image synchroni
