Description
You can allow the camera to control the exposure by
selecting Automatic, or you can set a specific
exposure rate.
NOTE: Increasing the manual exposure time may
affect the image rate.
You can allow the camera to control the iris by
selecting Automatic, or you can manually set it to
Open or Closed.
You can allow the camera to control the infrared cut
filter by selecting Automatic, or set the camera to
Color or Monochrome mode.
If your video image flickers because of the fluorescent
lights around the camera, you can reduce the effects
of the flicker by setting the Flicker Control to the same
frequency as your lights. Generally, Europe is 50Hz
and North America is 60Hz.
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
You can limit the automatic exposure setting by
selecting a maximum exposure level.
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.
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.
You can set Image Rate or Exposure as the priority.
When set to 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.
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.
