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 s to 1/5 s in PAL or 1/60 s to 1/6 s in NTSC). 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. AR18-08-B010 | v1.0 | 2009.03 Installation Manual Bosch Security Systems

the signal from a number of consecutive video fields to reduce
