Tampering Duration
The minimum Tampering Duration is the time for video analysis to determine whether camera
tampering has occurred. Minimum duration could also be interpreted as defining the tampering
threshold; a longer duration represents a higher threshold. The tampering duration time range is from
10 to 3600 seconds.
