4.Adjust the Object Size, History and Sensitivity profile sliders (see Motion Detection Parameters for details). Any detected motion within an active window is indicated by red peaks in the Activity window.

5.Click Save.

To exclude parts of the include window, select the Configure Excluded Windows and position the exclude window within the include window.

To delete an include or exclude window, select the window in the list of windows and click Del.

Motion Detection Parameters

The parameters controlling motion detection are described in the table below:

Parameter	Object Size	History	Sensitivity
Description	Object size relative to window	Object memory length.	Difference in luminance
	size.		between background and
			object.
High level (100%)	Only very large objects trigger	An object that appears in	Ordinary colored objects on
	motion detection.	the window triggers motion	ordinary backgrounds trigger
		detection for a long time	motion detection.
		before it is considered as
		non-moving.
Medium level (50%)			A large difference in luminance
			is required to trigger motion
			detection.
Low level (0%)	Even very small objects trigger	An object that appears in	Only very bright objects on
	motion detection.	the window triggers motion	a dark background trigger
		detection only for a very short	motion detection.
		time before it is considered as
		non-moving.
Recommended values	5–15%	60–90%	75–95%
Default values	15%	90%	90%

Note

•To trigger on small objects or movements, use several small motion detection windows rather than one large window and select a low object size.

•To avoid triggering on small objects, select a high object size.

•While monitoring an area where moving objects are not expected, select a high history level. This will cause motion detection to trigger as long as the object is present in the window.

•To only detect flashing light, select a low sensitivity. In other cases high sensitivity is recommended.
