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:

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.
