3.2 EXPOSURE
Exposure describes the brightness-related parameters,
which can be adjusted by EXPOSURE MODE, and AGC.

EXPOSURE MODE

You can set the EXPOSURE MODE as GLOBAL, BLC, and
WDR.
 GLOBAL
GLOBAL refers to the normal exposure mode which
performs exposure according to the whole image
brightness.
 BLC (Backlight Compensation)
BLC (Backlight Compensation) compensates light for the
front object to make it clear, but this may cause the over-
exposure of the background, where the light is strong.
 WDR (Wide Dynamic Range)
The WDR helps the camera provide clear images even
under backlight circumstances. When both very bright
and very dark areas simultaneously exist in the image,
WDR balances the brightness level of the whole image to
provide clear images with details.
AGC (Automatic Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MEDIUM,
or LOW.
Note:
The noise will be amplified when setting the AGC level.
The higher the level is, the more obvious the noise is.
3.3 DAY/NIGHT
COLOR, BW (Black White), and AUTO are selectable for
DAY/NIGHT switch.
COLOR
The image is colored in day mode all the time.
B & W (Black and White)

LIGHT turns on in the poor light conditions.
