VM D Confi gur ati on Examples
The sensitivity level examples below are provided only for illustration. Other factors such as
lighting level, contrast, and image noise may affect VMD performance and may require further
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 as in the
following figure.
Figure a-4
Wide Field of View
In a wide field of view camera, the car shown below would be expected to trigger a VMD alarm
if the VMD region-of-interest box is not larger than indicated by the red box.
Figure a-5
Combination Field of View
For cameras with a wide-angle field of view covering a large outdoor scene, people who walk
far away from the camera might appear rather small in the image. If motion needs to be
detected in the entire field of view, the following region-of-interest box configuration is
recommended.

Sensitivity Level Comparison: Normal Field of View

Sensitivity Level Comparison: Wide Field of View

• Three smaller boxes, set to 30% sensitivity, covering the upper portion of the
image where people appear small.
• Two larger boxes, set to 50% sensitivity, covering the lower portion of the image
where objects appear larger.
