White Balance
Configure
White Balance
settings.
•
Preset
: Use preconfigured white balance settings.
- Auto : Allow the system to adjust the white
balance automatically. The system will assess the
lighting conditions and adjust the white balance
automatically.
- Hold: Hold the current white balance.
-
INCANDESCENT - FLUORESCENT COLD
: Select
a lighting type to apply the appropriate white
balance.
If the Preset is Hold and the WDR mode is changed,
a reset is required.
• Manual : Adjust the white balance manually. Adjust
Red and Blue gain values. Greater the value, greater
the intensity of the corresponding color.
If the white balance does not work properly under
the following specific conditions, select
Manual
or
Hold.
- When the surrounding environment of the object
is out of the color temperature correction range
- When the surrounding environment of the object
is dark
- The camera is pointed directly at the fluorescent
lamp or installed in a place where the lighting
change is severe.

Configure
Exposure
settings.
•
Iris
: Select the lens IRIS type.
- Full Open: Select this to fully open the IRIS.
-
Auto
: Select this if a DC-type auto IRIS lens is
mounted.
•
IRIS Control Level:
Set the speed at which the
lens IRIS narrows. The higher the level, the slower it
narrows.
If the level is low, the screen causes day/night
hunting. In this case, set the level higher.
• AE Target Gain : Specify exposure compensation’s
target gain. Exposure is compensated automatically
based on the specified target gain. Higher the gain,
brighter the images.
•
Anti-Flicker:
If the lights in the area where the
camera is located use alternating current, specify
the frequency of the lights to minimize flickering.
Matching the frequencies can reduce flickering.
(NTSC: 60Hz, PAL: 50Hz) When using WDR, flickering
can be present in poor environments even if
Anti-
Flicker is turned on.
Depending on the camera module, WDR may not
work properly if Anti-Flicker and WDR are used
together. Please use only one of them in the camera
module.
•
Slow Shutter
: Activate
Slow Shutter
. The electronic
shutter’s speed will decrease to the specified level
under low-lighting conditions to allow more light in
and therefore produce brighter images.
• WDR: Disables or enables the WDR(Wide Dynamic
Range). When the very dark and very bright areas
exist simultaneously on the screen, WDR allows you to
recognize the both areas.
