EXPOSURE
BRIGHTNESS
Brightness refers to the brightness of the image. You
can set the brightness value from 1 to 10 to darken or
brighten the image. The greater the value is, the
brighter the image is.
EXPOSURE MODE
You can set the EXPOSURE MODE as GLOBAL, or BLC.
GLOBAL
GLOBAL refers to the normal exposure mode which
adjusts lighting distribution, variations, and
non-standard processing.
BLC (Backlight Compensation)
BLC (Backlight Compensation) compensates light to the
object in the front to make it clear, but this may cause
the over-exposure of the background where the light is
strong.
You can set the brightness value from 0 to 8 to darken
or brighten the image. The greater the value is, the
brighter the image is.
AGC (Auto Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MIDDLE,
or LOW. Select OFF to disable the AGC function.
Note:
The noise will be amplified when the AGC is on.
DWDR (Digital Wide Dynamic Range)
The digital wide dynamic range helps the camera
provide clear images even under backlight
circumstances. WDR balances the brightness level of
the whole image and provides clear images with details.

WB (White Balance)
White balance, the white rendition function of the
camera, is to adjust the color temperature according to
the environment. It can remove unrealistic color casts in
the image. You can set WB mode as ATW, or MWB.
ATW
Under the ATW mode, white balance is being adjusted
automatically according to the color temperature of the
scene illumination.
MWB
You can set the RGAIN/BGAIN value from 1 to 255 to
adjust the shades of red/blue color of the image.
