l
Exposure Offset: This is an advanced setting that allows you to compensate for unusual lighting
conditions by setting an exposure offset value. Negative values result in a persistently darker image, and
positive values result in a persistently brighter image.
l
Maximum Exposure: You can limit the automatic exposure setting by selecting a maximum exposure
level. The Maximum Exposure drop-down list is only available when the Exposure setting is set to
Automatic.
By setting a maximum exposure level for low-light situations, you can control the camera's exposure
time to let in the maximum amount of light without creating blurry images.
l
Priority: You can set Max Image Rate or Exposure as the priority.
l
When set to Max Image Rate, the camera will maintain the set image rate as the priority and will
not adjust the exposure beyond what can be recorded for the set image rate.
l
When set to Exposure the camera will maintain the exposure setting as the priority, and will
override the set image rate to achieve the best image possible.
l
Maximum Iris: You can limit the largest iris opening the lens will use by setting a maximum iris opening.
This value is an f-number. It is also given in EV relative to the widest possible opening of the lens. This
setting is only available when the Iris setting is set to Automatic.
The iris opening also affects how much of the scene is in focus. The smallest f-number (0 EV) sets the
iris to the widest possible opening. This allows the most light into the camera, but places less of the
scene in focus. Larger f-numbers (negative EV) result in a smaller maximum opening, placing more of
the scene in focus. The camera will automatically correct for the decreased light by using a higher gain
or a longer exposure time.
l
Preferred Iris: You can set an ideal iris opening to give a well-exposed and well-focused image in the
most frequent lighting conditions. This value is an f-number. It is also given in EV relative to the widest
possible opening of the lens. This setting is only available when the Iris setting is set to Automatic.
Note: The Preferred Iris value must be less than or the same as the Maximum Iris value.
The smallest f-number (0 EV) sets the iris to the widest possible opening. This allows the most light into
the camera, but places less of the scene in focus. Larger f-numbers (negative EV) result in smaller
openings, placing more of the scene in focus. The camera will automatically correct for the decreased
light by using a higher gain or a longer exposure time.
l
Backlight Compensation: If your scene has areas of intense light that cause the overall image to be too
dark, change the Backlight Compensation value until you achieve a well-exposed image.
l
Iris: You can allow the camera to control the iris by selecting Automatic, or you can manually set it to
Open or Closed.
l
Maximum Gain: You can limit the automatic gain setting by selecting a maximum gain level.
By setting the maximum gain level for low-light situations, you can maximize the detail of an image
without creating excessive noise in the images.
