Decreasing VMD sensitivity
If VMD alarms are triggered even when there is no motion and no large changes in the
video, the following adjustments will decrease VMD sensitivity:
• Increasing the sensitivity level from 30% to 50%, or from 50% to 80%. This should be
the primary adjustment mechanism, because it increases the required contrast level
(or amount of noise) required to trigger an alarm. Higher sensitivity levels also require
larger amount of motion to be observed before a VMD alarm is triggered.
• Increasing the size of the region-of-interest box. This adjustment will prevent smaller
objects (or smaller areas of noise) from triggering VMD alarms.
VMD configuration examples
These examples are provided only for illustration. Other factors such as lighting level,
contrast, and image noise may affect VMD performance and may require tuning
adjustments as described above.
Normal Field of View
In a normal field of view, with a person walking in front of the camera, the maximum
recommended region-of-interest box sizes would be as shown by the red boxes in
Figure 4-37 , Figure 4-38 , and Figure 4-39 .
