Set the Day/Night mode
In the Setup Menu, go to Day/Night and select the desired mode. The Day/Night
mode has four options: Auto, Color, B/W, and EXT1/EXT2.
Select Color to manually set the camera to color (day) mode.
Select Auto so that the camera can automatically switch between day (color) and
night (black and white) mode.
Auto mode:
Burst: Enable/disable the color burst component of the video signal when the
camera switches to B/W. ON mode maintains the same color signal in B/W so
that the video signal provides better compatibility with certain color
equipment. OFF mode removes the color burst signal B/W video and increase
the total TV lines.
Delay CNT: This is the time in seconds before Day↔Night switches. A long
delay response would be used, for example, to avoid switching from Night to
Day mode when car headlights pass in front of the camera.
Day→Night: Set the threshold level on how dark it should be before switching
from Day to Night mode. Lower (Higher) value makes the camera switched
from Day to Night at lower (higher) illumination
Night→Day: Set the threshold level on how light it should be before switching
from Night to Day mode.
CAUTION: If there is a minimal difference between the Day→Night and
Night→Day values, then camera may switch between Day and Night mode
repeatedly.
Color mode:
Color mode is used for normal lighting conditions.
B/W mode:
B/W mode can increase the sensitivity in low lighting conditions.
