5. To adjust the video image, make changes to any of the following settings as required:
Exposure: You can allow the camera to control the exposure by selecting Automatic, or you can
l
set a specific exposure rate.
NOTE: Increasing the manual exposure time may affect the image rate.
Iris: You can allow the camera to control the iris by selecting Automatic, or you can manually set it
l
to Open or Closed.
IR Cut Filter: You can allow the camera to control the infrared cut filter by selecting Automatic, or
l
set the camera to Color or Monochrome mode. When set to Automatic, the camera typically sets
the camera to color mode during the day when there is lots of light, and changes to monochrome
mode at night to use the infrared light to detect objects in the scene.
Flicker Control: If your video image flickers because of the fluorescent lights around the camera,
l
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.
Backlight Compensation: If your scene has areas of intense light that cause the overall image to be
l
too dark, change the Backlight Compensation value until you achieve a well exposed image.
Maximum Exposure: You can limit the automatic exposure setting by selecting a maximum
l
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.
Maximum Gain: You can limit the automatic gain setting by selecting a maximum gain level.
l
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.
Priority: You can set Image Rate or Exposure as the priority.
l
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.
Saturation: You can adjust the video's color saturation by entering a percentage number. 0 creates
l
a black and white image, while 100 creates intense color images.
Sharpness: You can adjust the video's sharpness by entering a percentage number. 0 applies the
l
least amount of sharpening, while 100 applies the most sharpening to make the edges of objects
