as the continuous motion of the fan would automatically increase the required motion detect
trigger level.
Another consideration with adaptive motion detect is that when a continuous level of motion is
introduced into a scene, the motion detect sensitivity decreases. The result is that some motion
may not be detected when a continuous dynamic scene exists. For example, a person walking
through a scene with windblown trees may not trigger the motion detect capture that would
normally be triggered when there is no wind and the trees are not moving.
The sensitivity level for motion detect is the only user-configurable parameter for Motion Detect
operation. A value of 1 is the least sensitive motion detect threshold setting and a value of 99 is
the most sensitive motion detect threshold setting. Motion detect can be a complicated feature
to implement. Campbell Scientific recommends initially setting the motion detect threshold to 50
and adjust it to get the best setting for the application.
FIGURE 14-13. Live Video Motion Detect Level
If the camera is not detecting the desired motion, increase the motion detect sensitivity level. If
the camera produces too many false triggers, decrease the motion detect sensitivity level. Note
that the camera can falsely detect or not detect motion due to too many variables. In some cases
where motion detect of a small object is required, it may be necessary to set a motion detect
level that will also produce frequent false triggers.
