3.1 VIDEO FORMAT
You can set the video format to 8MP@12.5fps,
8MP@15fps, 5MP@20fps, 1080p@25fps, or
1080p@30fps.
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 that
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 a camera setting that prevents the
appearance of horizontal lines (banding) when
photographing images in low frequency light and high
brightness environments.
3.3 VIDEO SETTINGS
Move the cursor to VIDEO SETTINGS and click Iris+ to

IMAGE MODE
IMAGE MODE is used to adjust the image saturation,
and you can set it to STD (Standard), HIGH-SAT (High
Saturation), or HIGHLIGHT (better indoor facial details).
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 WHITE BALANCE mode to AUTO,
or MANUAL.
AUTO
Under AUTO mode, white balance is being adjusted
automatically according to the color temperature of the
scene illumination.

You can set the R-GAIN/B-GAIN value to adjust the

BRIGHTNESS
Brightness refers to the brightness of the image. You
can set the brightness value from 1 to 9 to darken or
brighten the image. The greater the value is, the
brighter the image is.
CONTRAST
This feature enhances the difference in color and light
between parts of an image.
SHARPNESS
Sharpness determines the amount of detail an imaging
system can reproduce.
SATURATION
Saturation is the proportion of pure chromatic color in
the total color sensation. Adjust this feature to change
the saturation of the color.
3DNR (3D DNR)
3DNR refers to 3D digital noise reduction. Comparing
with the general 2D digital noise reduction, the 3D

12
digital noise reduction function processes the noise
between two frames besides processing the noise in
one frame. The noise will be much less and the video
will be clearer.
MIRROR
OFF, H, V, and HV are selectable for mirror.
OFF: The mirror function is disabled.
H: The image flips 180° horizontally.
V: The image flips 180° vertically.
HV: The image flips 180° both horizontally and
