This setting determines what level of movemen t is required to trigger a motion-sensitive image capture .
Lower numbers increase sensitivity, so smaller changes in the image can trigger a capture.
On the other hand larger values decrease sensitivity, which result in more or larger changes without triggering a capture. Valid values are 0-100 . Lower values increase sensitivity while higher value decrease sensitivity, allowing for wider variation in light levels. Valid values range from 0-100 . Some good examples of video noise are trees, leaves or tall grass on a very windy day , distant lights that flash on and off , etc.
