Enable Defog
Enable this feature from Video & Audio > Camera Settinos to counter the effects of foggy weather and get a clear image. Or click
the Defoo button in the product's Live View page. This button can be configured to appear in the Live View page from Live View
Confio > Live View Layout. Use the Defoo Effect slider to adjust the degree of countering as required.
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 Settinos
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
rare light conditions disabling WDR might give a better image.
Important
Use WDR in combination with automatic exposure control. Other exposure settings could give undesirable results.
Exposure Settings
Exposure value - Use the Exposure value slider to adjust the overall brightness of the image.
Exposure control - Exposure is the amount of light the camera's sensor captures for a scene. Too much light results in a washed out
photo and too little light results in a dark scene. Select a suitable option to control exposure.
The Flicker-free 50 or 60 Hz option removes flicker that is caused by fluorescent and other light sources. The Hold current option
locks the current exposure settings.
Enable Backlioht compensation - Enable this option if a bright spot of light such as a light bulb, causes other areas in the image
to appear too dark.
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. However, prioritizing low noise may result in a very dark image, especially in low light situations.
