Customizing Motion Detection with Masking
Masking an Area of the Video Feed
First, try setting a
mask at the top of
the door, before
using the Invert
Mask command.
Masking Part of a Video Feed from Motion Detection
126
By default, motion is detected everywhere in a video feed. Some of that movement may not
be of any interest, such as a roadway in a window, or a door that many people walk by.
Areas of no concern can be masked—that is, they are hidden from motion detection—so
that they do not trigger an alarm.

After setting the mask, right-click the mouse on the image. A menu appears (see
Figure

Select the Invert Mask command; the detection is now focused on an area that
moves only when the door opens.
4.
Enable Log or Alarm. The log can be used to obtain video from the time(s) when the
door is opened, saving a unit operator from having to search through video.
Red Mask and Green Mask
In motion detection, when the mask is red, movement behind a mask is ignored.
The masking behaves opposite to that of motion search. In motion search, the parts that
are masked in green act as motion triggers rather than as a mask.
