a. Set the IR Cut Filter to Monochrome. The changes to the IR Focus Offset setting are not visible in
color mode.
b. Move the IR Focus Offset slider to the left to focus on closer objects and move the slider to the
right to focus on farther objects.
c. Set the IR Cut Filter back to Automatic.
NOTE: The IR Focus Offset setting is reset each time you change the Zoom or Focus setting.
5. (HD Multisensor Dome Camera only) If you are adjusting a multi-head camera, there are options that apply
to the camera as a whole or to individual heads.
a. Select the All Heads tab to adjust the settings that apply to the whole camera.
b. In the All Heads tab, you can set the Imaging mode to Global or Per-head:
l Global — apply the same settings to all camera heads. Use the settings listed in the All
Heads tab to adjust the camera image settings. The same settings for each numbered tab is
disabled.
l Per-head — apply different settings to each camera head. Select the different tabs to
change the settings for each camera head.
c. Select each numbered tab to adjust the zoom and focus controls for each camera head. These
settings must be manually adjusted for each camera head.
6. To adjust the video image, make changes to any of the following settings as required:
l Exposure: 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.
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 IR Cut Filter: You can allow the camera to control the infrared cut filter by selecting Automatic, or
setting 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.
If you select External, the camera's IR Cut Filter will be triggered based on the digital input state.
NOTE: The default digital input state must be configured on the Digital Inputs and Outputs page.
l Flicker Control: 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.
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 Maximum Exposure: 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.
