Motion Region
You can define the motion detection region within the image that camera captures, so this camera
will ignore motions which are not covered by the motion region setting, and reduce the chances of
false alarm.
The descriptions of every setting in this menu will be given below:
Region 1 – 3 Check the box to enable motion detection region 1 to 3. You can
check multiple boxes to enable multiple motion detection regions.
When you checked a box, a new region (and region number) will
be displayed on captured image.
Sensitivity Move the slide bar to change the motion detection sensitivity
setting: Drag the slide to the right to increase sensitivity (camera
will detect minor changes in the image), and drag the slide to the
left to decrease sensitivity (camera will only detect major changes
in the image).
Refresh In case the objects of the image captured by the camera moved,
click this button to reload the image captured by camera, so you
can decide the motion detection region more precisely.
Save Save motion detection region settings.
