Wide dynamic range settings
WDR improves the image quality and amount of detail in high contrast
scenes. High contrast scenes consist of areas with different lighting
conditions; some areas are bright and others are dark. Without WDR,
either the bright areas would be overexposed (too bright) or the darker
areas would be completely dark. WDR can produce more detail in both
the dark and the bright areas of the image.
o Wide Dynamic Range—Set the level of digital Wide Dynamic Range
(dWDR) to Off, Low, Mid, or High. When enabled, the camera digitally enhances the details in each
frame.
o Wide Dynamic Range Shutter—Enables True WDR. The camera combines two frames taken with
slow- and fast-exposure shutter speeds into a single frame with a wide dynamic range, determining the
optimal mix of regions within the scene.

White Balance—Set according to operating environment:
o Auto (default)—Computes the white balance value output using color
information from the entire screen. It is suitable for an environment with a
light source color temperature in the range of approximately 2,700 ~
7,500K.
o One Push—Click One Push Trigger to activate the factory-optimized
setting for white balance. This setting might not be ideal for every lighting environment.
o ATW (Auto Tracking White Balance)—Automatically adjusts the white balance in a scene while
temperature color is changing. It is suitable for an environment with a light source color temperature in
the range of approximately 2500 ~ 10,000K.
o Manual—Define the Rgain and Bgain between 0-100 to increase the red and blue luminance.

Noise reduction settings
Noise reduction settings are used to reduce or eliminate artifacts that can
limit the ability to positively identify an object. There are two types of
noise: luminance and color (chroma) noise. 3D noise reduction and 2D
noise reduction settings reduce luminance noise: dots of varying
brightness levels (black, white, and gray). It is not recommended to
completely eliminate luminance noise, which can result in unnatural
images. The 3D Noise Reduction and 2D Noise Reduction settings should
be configured after configuring Color Noise Reduction.
o Color Noise Reduction—Controls the noise appearing as red, green
and blue dots between light and dark areas. Four settings are available:
Off, Low, Mid, High. High maximizes the blending of the color noise with the image, effectively
removing the dots, while Low minimizes the blending.
o 3D Noise Reduction—Provides superior noise reduction and is recommended for use in extra low-
light conditions. It is especially useful for reducing blur with moving objects. 3D noise reduction
reduces image noise/snow in low-light conditions by comparing adjacent frames. A higher level of 3D
noise reduction generates relatively enhanced noise reduction, although it creates more motion blur
than 2D noise reduction on moving objects. Four settings are available: Off, Low, Mid, High.
o 2D Noise Reduction—Analyzes individual frames pixel by pixel and frame by frame to eliminate
environmental noise and deliver optimized image quality, especially in low-light conditions. 2D noise
reduction tends to produce superior results for moving objects when applied to areas in the field of
