2. Click <Event setup>.
3. Select <Tampering detection> from
<Event action setup>.
4. Set whether or not to <Enable>.
5. Specify the detection sensitivity of the
scene change.
The higher the sensitivity is, the lesser
change can be detected.

activation condition.

The default change detection function may not work properly in the following cases:
-
A monotonous background or a night/low-contrast scene may deteriorate the detection
performance.
-
A severe shaking of the camera or a drastic change to the illumination can be considered a
scene change by mistake.
-
Detection of the scene change may take some time (maximum 3 seconds) right after the
change was made.
-
Once a scene change is detected, the network camera will resume a normal operating after a
certain stability time (approx. 3 seconds) during which no detection will be performed.
