How to Set Video Tampering (WEB 5.0)

This knowledge base article provides instructions on setting up the Video Tampering function for devices using the WEB 5.0 firmware. Video Tampering detects unauthorized attempts to obstruct or disable the camera, such as covering the lens, and triggers alerts to maintain the integrity of the surveillance system.
 

The Video Tampering function is crucial for maintaining the effectiveness and reliability of your surveillance system. By detecting attempts to cover or block the camera, this feature helps ensure that your security setup remains operational and alerts you to potential tampering or sabotage. Proper configuration of this function enhances security by providing timely notifications when the camera's view is compromised.
