Scene Change Detection
The Scene Change Detection page allows the user to adjust the settings of the scene change detection
algorithm. The scene change detection module resets the tracking algorithm when it detects a large
persistent change in the image. This prevents the tracking algorithm from detecting image changes as
tracked objects which can be potential sources of false alarms.
There are 3 options for the scene change mode:
• Automatic: Default setting. Uses the recommended settings.
• Manual: Allows the user to adjust the parameters used by the scene change detection algorithm.
• Disabled: Scene change detection is disabled.
Note: To see the output of the scene change detection on the image, Scene Change diagnostics
metadata must be enabled on the VCA -> Advanced page. Please refer to Advanced Settings for more
information. It's only possible to see the detection diagnostic data when in Manual mode.
Manual Scene Change Detection Settings
In the manual mode the following settings are available:
• Changed Time: The length of time that the image must be persistently changed before the scene
change is triggered and the tracking algorithm is reset.
• Changed Screen Area: Percentage area of the image which must be changed for the scene
change to be triggered and the tracking algorithm to be reset.
If false scene change detections are a problem, the time and/or area should be increased so that large
transient changes such as a close object temporarily obscuring the camera do not cause false scene
change detections.
