S
Saturation
The amplitude of the chrominance signal affecting the vividness
of the color.
Sensitivity
A measure of the amount of light required to provide a standard
video signal. Sensitivity values are stated in lux (
see
Lux).
SensUp (sensitivity up)
Increases camera sensitivity by increasing the integration time
on the CCD (lowering shutter time from 1/50 to 1/5 s). This is
accomplished by integrating the signal from a number of
consecutive video fields to reduce signal noise.
Signal-to-noise ratio
The ratio between a useful video signal and unwanted noise
measured in dB.
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.
