3.2 EXPOSURE
EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, HLC,
WDR, or HLS.
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
over-exposure of the background where the light is
strong.
 HLC (Highlight Compensation)
HLC stands for highlight compensation. The camera
detects strong spots (over-exposure portion of image)
and reduces the brightness of strong spots to improve
the overall images.
 WDR (Wide Dynamic Range)
The wide dynamic range (WDR) function helps the
camera provide clear images even under back light
circumstances. When there are both very bright and
very dark areas simultaneously in the field of view, WDR
balances the brightness level of the whole image and
provides clear detailed images.
HLS (Highlight Suppression)

It is the same visual effect as the solar eclipse. If the
brightness of a part in the image exceeds the threshold,
this part will become black. Then whole image can be
clear.
AGC (Auto Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set to HIGH, MEDIUM,
or LOW.
Note:
The noise will be amplified when setting the AGC level.
ANTI-BANDING
ANTI-BANDING is to prevent the phenomenon of
horizontal lines (banding) when photographing images
in low frequency light or high brightness environments.
3.3 LIGHTING SETTINGS
LIGHTING MODE
IR and WHITE LIGHT are available.
 IR
IR LIGHT

You can turn on/off the IR LIGHT to meet the
requirements of different circumstances.
SMART IR

The Smart IR function is used to adjust the light to its
most suitable intensity, and prevent the image from
over exposure.
D N Threshold (Day to Night Threshold)

Day to Night Threshold is used to control the sensitivity
of switching the day mode to the night mode. You can
set the value from 1 to 9. The larger the value is, the
more sensitive the camera is.
