VMD detection window
The VMD detection window shows up as a small picture within the larger picture. Depending
on the thresholds set, the motion detection bar on the right side of the picture shows up
green or red (see figures below), the latter indicating a VMD alarm will be generated. In the
pictures, the upper and lower thresholds are shown as two white markers. If the bar runs over
the highest marker, it will turn green again and there will be no alarm condition.
VMD detection windows, with mask applied to the left half of the window. The small white blocks
indicate grid elements where change occurred above the sensitivity level. The summed change is
reflected in the bars on the right, the green one (left) not reaching the lower threshold. The red
one (right picture) extending past it, since this threshold is set much lower.

VMD alarm
If movement is detected, a module alarm (VMD) will be generated and sent out over the
network using the (unsolicited) notification mechanism. Such alarms can be caught using
appropriate software.
