DAYNIGHT  camera  is  a  low  brightness  camera,  which  improves  the  sensitivity
by  operating  with  a  color  mode  at  the  over  of  regular  brightness  and  operated
with  a  B/W  mode  by  canceling  the  IR  Cut  function  at  the  below  of  regular
brightness. Also, it can be used linked with the separated infrared ray emission
device.  SCC-B2391(P)/B2091P  has  a  high  resolution  with  the  540  TV  Lines  of
horizontal resolution through the digital signal processing and OLPF.
In the mechanical fluorescent light environment, if you attach MANUAL IRIS
LENS and turn the ELC switch among FUNCTION switches on, color may be
rolled.
In this case, supply AC power before you turn L/L switch among FUNCTION
switches on. (NTSC:60HZ , PAL:50HZ)
Chapter 1    Introduction
[DAYNIGHT]
It is a function of a color camera to delete the fiter with
the IR Cut function in an illumination below the standard
value so that it has a better sensitivity.
COLOR ROLLING is the problem that color on the
monitor screen changes non-periodically.
This happens when White Balance is not fixed,
because a mechanical fluorescent light flickers
when it’s cycle is the same to the cycle of the power
frequency.
