There are three types of sabotage detection in the Tamper Detection Setting tab on the
Video Analytics tab: blinding the camera, blurring the video display, and tampering with the
camera field of view. The user should note that when the following conditions are
applicable, the tamper detection features should be manually disabled to avoid raising false
alarms:
• During the configuration of the video display
• While text is overlaid on the video
• If the video display becomes too dark
