The default tampering detection function may not work properly in the following cases:
-
Under circumstances of simple background or low illumination and night time may lower the
detection sensitivity.
-
A severe shaking of the camera or a drastic change to the illumination can be considered a
tampering by mistake.
-
Detection of the tampering may take some time (maximum 5 seconds) right after the
tampering was made.
-
Once a tampering is detected, the camera will resume a normal operating after a certain
stability time (approx. 5 seconds) during which no detection will be performed.
