• Interval: The tampering detecting interval. Take the diagram below as
example. The interval is set for 30 second; the camera lens is covered
during 10 - 40 sec. At time point B, the camera compares the view with
time point A, and sends an alarm when it founds that the lens is covered.
At time point C, the camera compares the view with time point B, and
sends an alarm when it founds that the lens is uncovered.
