Note
Too much brightness can negatively impact image quality when defog is active.

White Balance

To change this setting go to Setup > Video & Audio > Camera Settings
White balance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis
product 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. For a description of each available setting, see the online help
The white balance window is enabled for the Automatic and Automatic outdoor options that appear in the White balance drop-down
list. Select one of the options from the drop-down list to set the white balance window properties. Select Automatic to use the
default settings for the Automatic and Automatic outdoor options (in the White balance drop-down list). Select Custom to manually
set a reference window for white balance in the view area.
Wide Dynamic Range
Wide dynamic range (WDR - Forensic Capture) provides balanced images in scenes when there is a considerable contrast between
light and dark areas in the image. The camera automatically handles the transition between such scenes and low-light conditions. In
complex light conditions disabling WDR might give a better image.
Important
Use WDR in combination with automatic exposure control. Other exposure settings could produce undesirable results.
Note
WDR is only available if you have selected a capture mode that supports WDR. See Configure capture mode on page 10.

Exposure Settings

Exposure is the amount of light the camera's sensor captures for a scene. Too much light results in a washed out image and too
little light results in a dark image.
Exposure value - Use the Exposure value slider to adjust the overall brightness of the image.
Exposure control - Select a suitable option to control exposure.
For most scenes, the Automatic option will provide the best results. The shutter speed is automatically set to produce optimum
image quality. Fluorescent lamps or other light sources can sometimes cause flickering in the image. To reduce flicker in the image,
select the Flicker option that matches the power line frequency.
The Hold current option locks the current exposure settings.
Max exposure time - Shutter speed, also called 'exposure time', stands for the length of time the camera shutter is open, thereby
exposing the camera sensor to light. If shutter speed is fast it can freeze action effectively. If shutter speed is slow, it can cause
moving objects to appear blurred. Decreasing the exposure time will reduce motion blur.
Exposure zones - This setting determines which part of the image is used to calculate the exposure. For most situations, the Auto
setting can be used.
You can select a predefined area by defining Include and Exclude windows within the image. Exclude windows exclude areas that are
too bright or dark, and Include windows include areas in the scene that have better lighting which will contribute to the exposure data.
There must be at least one Include window. There can be a total of ten Include and Exclude windows to tailor the exposure zone.
Note that an Exclude window is effective only when placed inside an include window.
Tip: If an area is extremely bright, draw an Include window to cover the whole area and define Exclude windows within it to
block out the bright areas.
Exposure priority - When Motion is prioritized and maximum Shutter time is set to a small value, motion blur in the image is
minimized. This can be useful for recognition of moving objects such as people and vehicles.
However, prioritizing motion may cause an increase in image noise, especially in low light situations. When Low noise is prioritized
and Gain is set to a small value, image noise is minimized. The file size is also reduced, which can be useful if storage space or
bandwidth is limited. Be aware that prioritizing low noise may result in a very dark image, especially in low light situations.
