Refer to 9.1 Face Detection for steps to configure scene change detection.
Sensitivity in the Rule Settings ranges from 1 to 100, and the higher the value, the more easily the
change of scene will trigger the alarm.
For analog cameras, the line crossing detection and intrusion detection conflict with other VCA
detection such as sudden scene change detection, face detection, and vehicle detection. You can
enable only one function. If you have enabled line crossing detection or intrusion detection, when
you enable sudden scene change detection and apply the settings, the following attention box pops
up to remind you there are not enough resources and asks you to disable the enabled VCA type(s) of
the selected channel(s).
