Tamper detection
You can detect tampering of cameras and video cables by means of various options. Run a
series of tests at different times of the day and night to ensure that the video sensor is
operating as intended.
The options for tamper detection can only be set for fixed cameras. Dome cameras or other
motorized cameras cannot be protected in this manner as the movement of the camera itself
causes changes in the video image that are too great.

Global change
Select the check box if the changes, set with the
Global change
slider, should lead to trigger
an alarm.
Move the slider to set how large the changes in the video image must be for an alarm to be
triggered. Set a high value if changes that occur simultaneously in few areas should lead to
