park applications.
R

detection algorithm to identify motion.
Resolution
The measure of the fine detail that can be seen in an image. For
analog systems this is typically measured in horizontal
Television Lines or TVL. The higher the TVL rating, the higher
the resolution.
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.
