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.
