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.
