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.
Automatic Backlight Compensation -
The image is automatically corrected to compensate for small and very bright areas behind the
subject of interest. If required fine-tune this further through the use of the
Exposure value
slider.
Exposure value -
Use the
Exposure value
slider to adjust the overall brightness of the image.
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.
Shutter & Gain
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. The Axis product allows 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). A slow shutter speed 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
to set the shutter speed automatically. If required, use
Max shutter
to limit the shutter speed to prevent the frame
rate from being reduced.
For example, to get 30 fps, set
Max shutter
to 1/30.
•
Fixed
to use a fixed shutter speed.
Gain
, measured in decibel (dB), 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.

to use a fixed gain.
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noise and produce smaller image files.
Image Settings
Image freeze on PTZ -
Select
All movements
to freeze the image while the camera is moving during a pan, tilt or zoom operation.
Once the camera reaches its new position, the view from that position is shown.
Presets
freezes the image only when the camera
moves between preset positions.
