Motion Detection

Motion detection is used to generate an alarm whenever movement starts or stops in the camera view.

Motion detection is configured by defining up to 10 Include and Exclude windows:

•Include windows — define areas where motion should be detected

•Exclude windows — define areas within an Include window that should be ignored (areas outside Include windows are automatically ignored).

For instructions, see Set Up Motion Detection Windows on page 30.

To control the number of motion detection alarms, the parameters Object Size, History and Sensitivity can be adjusted. See Motion Detection Parameters on page 30.

Note

•Using the motion detection feature may decrease the product’s overall performance.

•The position of the Motion Detection Window is relative to the orientation of the Camera. Changing the orientation of the camera will also change the position of the Motion Detection Window.
