The shutter and gain settings affect the amount of motion blur and noise in the image. To adapt to
different lighting, available storage space and bandwidth, it is often necessary to prioritize either low
motion blur or low noise. This camera allows using different prioritization in normal light and in low light.
Shutter speed is related to the amount of time the shutter is opened and is measured in seconds (s).
Mode:
The automatic mode supports the automatic exposure function for automatically adjusting the
sensor’s gain, shutter time and diaphragm so that the images achieve the appropriate brightness. The
manual mode supports the manual exposure control function for manually adjusting the gain and shutter
time.
Slow Shutter: A slow shutter allows more light to reach the sensor and can help produce a brighter
image in low light situations. On the other hand, a slow shutter speed can cause moving objects to appear
blurry.
Auto Iris: This function is used for controlling the shutter time, gain and diaphragm of the mechanical iris
lens to adjust the luminance. In this mode, it is also possible to adjust the luminance using the gain and
iris diaphragm while keeping the exposure time fixed.
Shutter:
Used to for controlling the gain while keeping the shutter time fixed to adjust the luminance.
Max. Shutter:
Adjust the Max. Shutter speed in the range.
Gain: Gain is the amount of amplification applied to the image. A high gain may provide a better image in
low light situations but will increase the amount of image noise.
Max. Gain:
Adjust the Max. Gain in the range.

AWB
Auto White Balance control is used to make colors in the image appear the same regardless of the color
temperature of the light source. This camera can be set to automatically identify the light source and
compensate for its color. Alternatively, select the type of light source from the drop-down list.
Mode: Configure the options for White Balance. The default setting is ATW-Indoor.
Cb Gain:
Adjusts the picture output in the blue range. The White balance B gain can be adjusted in the
range, where a higher value produces a bluer image.
Cr Gain:
Adjusts the picture output in the red range. The White balance R gain can be
adjusted in the
range, where a higher value produces a redder image.
