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.
