Global

: Global refers to the normal exposure mode which adjusts lighting distribution, 

variations, and non-standard processing.

 

BLC

 (Backlight Compensation): If the background is very bright compared to objects in front, BLC 

brightens objects in the front to make them more visible. 

 

HLC

 (High Light Compensation): HLC masks strong light sources that excessively brighten areas 

of the scene. This makes it possible to see details of the image that would normally be darkened 
by the camera’s brightness compensation.

 

WDR

 (Wide Dynamic Range): Use WDR to help the camera produce clear images even with 

strong backlight. WDR balances the brightness level of the whole image and provides clear 
images with details. When WDR is selected as the exposure mode, you can set it as low, 
medium, high or off.

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. Select Off to disable the AGC function. 

NOTE

: The noise is 

amplified when the AGC is on.

Slow Shutter

: Slow Shutter increases the exposure time of a single frame, which makes the camera 

more sensitive to light. Therefore, it can produce images even under low lux conditions. You can set 
the Slow Shutter as Off, x2, x4 under 8 MP @ 15 fps, or 8 MP @ 12.5 fps mode, and as Off, x2, x4, x6, 
x8, or x16 under other modes according to different light conditions.

WB (White Balance) submenu

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 to Auto, Manual, 
or Natural.

Auto

: Under Auto mode, white balance is being adjusted automatically according to the color 

temperature of the scene illumination.

Manual

: Click Iris+ to enter the submenu, you can set the R Gain/B Gain value from 1 to 255 to adjust 

the shades of red/blue color of the image.

Natural

: Set the white balance as the Natural mode, when large part of the monitoring scene is 

monochrome.

Day Night submenu

Color, BW (Black White), and AUTO are selectable for DAY and NIGHT switches.

 

 

Color

: The image is colored in day mode all the time.

B/W

: The image is black and white all the time, and the IR light turns on in the poor light conditions.

Auto

: The image switches from color to B/W, or from B/W to color automatically according to the 

light conditions. Click 

Iris+

 to enter the submenu, you can turn on/off the IR Light and set the value of 

Smart IR in this menu.

 

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. You can turn on/off this function.

 

D/N Threshold (Day to Night Threshold)

: Use the Day to Night Threshold to control the 

sensitivity of switching the day mode to the night mode. You can set the value from 1 (less 
sensitive) to 9 (more sensitive). 

 

N/D Threshold (Night to Day Threshold)

: Use the Night to Day Threshold is used to control 

the sensitivity of switching the night mode to the day mode. You can set the value from 1 (less 
sensitive) to 9 (more sensitive). 

Video Settings submenu

Move the cursor to Video Settings and click 

Iris+

 to enter the submenu. Use this submenu to adjust the 

Contrast, Sharpness, Saturation, 3D DNR, Mirror and Defog.

Contrast

: This feature enhances the difference in color and light between parts of an image. You can 

set the Contrast value from 1 to 10.

Sharpness

: Sharpness determines the amount of detail an imaging system can reproduce. You can 

set the Sharpness value from 1 to 10.

Saturation

: Use this option to change the color intensity. The value ranges from 1 to 10.

3D DNR (Digital Noise Reduction)

: Use the 3D DNR option to decrease video noise, especially 

when capturing moving images in low light conditions, to produce a better image quality. You can set 
the 3D DNR value from 1 to 10.

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.

 

H, V, HV

: The image flips horizontally, vertically, or both horizontally and vertically.

Defog

: It is used in special environments such as the foggy or rainy weather, or in high illumination 

conditions, in which the image appears hazy. Enable the defog function can enhance the subtle details 
to display clear images.

Factory Default

Click 

Iris+

 to enter the submenu, and click 

OK

 to reset all the settings to the factory default. Click 

Cancel

 

to return to the menu without resetting the camera. 

Save & Exit
