In the Video Analytics tab, you can configure the tamper detection threshold
settings for blur, blinding, and scene changes. Each setting has three threshold
levels: high (80%), medium (50%), and low (30%). When these thresholds are
exceeded, a message appears on the screen to indicate that possible dome
tampering has occurred.
To prevent false alarms, the tamper detection features should be manually
disabled under the following conditions:
•
During the configuration of the video display
•
While text is overlaid on the video
•
If the video display becomes too dark
