3. Adjust the size (drag the bottom right-hand corner) and the position (click on the text at the top and drag to the desired
position) of the window.
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

Medium level (50%)
Low level (0%)

Default values
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.

Object Removed

Object Removed is used to trigger an alarm if an object, within a pre-defined area of interest, is removed. Object Removed provides
tools to define:
Area of interest - This is a virtual area that is defined around an object to detect if that object has been removed from the scene.
Object size - Defines the size of the objects that should be detected.
Sensitivity - Use this slidebar to define how sensitive the detection should be.
Object Size
Object size relative to window
size.
Only very large objects trigger
motion detection.
Even very small objects trigger
motion detection.

History
Object memory length.
An object that appears in
the window triggers motion
detection for a long time
before it is considered as
non-moving.
An object that appears in
the window triggers motion
detection only for a very short
time before it is considered as
non-moving.

Sensitivity
Difference in luminance
between background and
object.
Ordinary colored objects on
ordinary backgrounds trigger
motion detection.
A large difference in luminance
is required to trigger motion
detection.
Only very bright objects on
a dark background trigger
motion detection.
