There are three types of sabotage detection in the Tamper Detection Setting pane on the
Video Analytics tab: blinding the camera, blurring the video display, and tampering with the
camera field of view.
Avoiding False Alarms
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

this occurs, video blurring in the field of view is detected and an alarm message appears
(see Figure ) above the video display. To detect video blurring:
1. Click the Video Analytics tab.
