Smart BLC (Back Light Compensation)

Smart back-light compensation allows the camera to automatically compensate for bright areas of a high contrast scene without having to define a window or area.

U

UTP (Unshielded Twisted Pair)

A variant of twisted pair cabling, UTP cable is not surrounded by any shielding. The wires in a twisted pair cable are twisted around each other to minimize interference from the other twisted pairs in the cable. UTP is the primary wire type for telephone usage and the most commonly used type of networking cable.

	V
VMD	Video Motion Detection: An algorithm for motion detection in
	which the camera compares the current image with a reference
	image and counts the number of pixels that have changed
	between the two images. An alarm is generated when the
	number of pixel changes exceeds a user-configured threshold.

W

WDR (Wide Dynamic Range)

A cameras dynamic range is the difference between the minimum and maximum acceptable signal levels. A scene with both very low and very high illumination levels requires a camera with a wide dynamic range to handle it correctly and produce a useful image.
