	size.		between background and
			object.
High level (100%)	Only very large objects trigger	An object that appears in	Ordinary colored objects on
	motion detection.	the window triggers motion	ordinary backgrounds trigger
		detection for a long time	motion detection.
		before it is considered as
		non-moving.
Medium level (50%)			A large difference in luminance
			is required to trigger motion
			detection.
Low level (0%)	Even very small objects trigger	An object that appears in	Only very bright objects on
	motion detection.	the window triggers motion	a dark background trigger
		detection only for a very short	motion detection.
		time before it is considered as
