Exposure value -
Click in the bar to fine-tune the exposure.
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.
If the image flickers that can be caused by fluorescent lamps or other light sources. 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.
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. For particular requirements, select a predefined area by defining Include and Exclude windows within the image
to exclude areas that are too bright or dark, and 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
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). 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.

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.
•

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 set the gain automatically. If required, use

When
Shutter
and
Gain
are both set to
Auto
, it is possible to set the
Priority
between low motion blur and low noise manually and to
use a different
Priority
in
Normal Light
and in
Low Light
.
Example
Consider an area where people or vehicles move during the day, but where there should be no movements during night. To be able to,
for example, recognize faces or license plates, move the normal light priority slider toward low motion blur. At nighttime, motion
detection is more important than identification. Motion blur is acceptable and since low light can cause a lot of noise, move
the low light priority slider toward low noise.
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noise and produce smaller image files.
Iris adjustment
Select
Enable automatic iris adjustment
to automatically compensate for changing light conditions. This option is not available
if a fixed iris is used.
Use the
Iris adjustment
slider to set the preferred F-value. The scale represents the amount the iris is open. If set to 0, the iris is
opened as much as possible. If set to 100, the iris is closed as much as possible. The actual F-value is shown below the slider. If
