Optical Zoom �imit
Select to limit the Oracle Domes optical zoom function. �y default
‘100�’ is selected and the camera can zoom to its ma�imum
capabilities. The optical zoom function can be limited to between
75% and 100% magnification.
ICR
Oracle Domes with day�night cameras ha�e an �nfrared Cut
Remo�al (�CR) function which can enhance the camera’s
sensiti�ity in low light conditions as well as allowing infrared
illumination to be used (infrared is blocked by the �R cut filter).
�hen �CR is ON, the camera switches to monochrome mode, the
�R cut filter is remo�ed and the camera is at its most sensiti�e.
The default setting for the camera is �UTO �CR where the filter
is controlled automatically dependent on the scene brightness
determined by the camera. The camera can be forced to stay in
colour mode by setting �CR to OFF, or can be forced into mono
with ma�imum low light sensiti�ity by setting �CR to ON.
�lternati�ely �CR switching can be triggered in response to an
alarm input. This allows a photocell sensor to be connected to
one of the dome’s alarm inputs to control the �CR. This method
can be used to a�oid instability that may occur when the camera
controls the �CR switching in marginally low light conditions.
Remo�ing the �R cut filter due to low light can cause enough of an
increase in scene brightness and �ideo le�el to make the camera
return the �R cut filter and switch immediately back to colour
mode (at which point the �ideo le�el drops and the process is
repeated).
�hite �alance
The Oracle Domes �hite �alance feature enables the camera to
compensate for different lighting scenarios which can effect the
colour quality of the displayed image. Select ‘�uto’ for the camera
to auto-compensate for white balance depending on current �iew.
Select ‘�ndoor’ to permanently set for best results in an indoor
setting. Select ‘Outdoor’ to permanently set for best results in an
outdoor setting.
��posure
The Oracle Domes ��posure setting can be set to maintain
optimum contrast settings for the �iewed image�camera location.
Select ‘Full �uto’ for the camera to auto-compensate for best
e�posure settings depending on current �iew. Select ‘�anual’ to
manually configure e�posure settings. Select ‘Shutter �riority’ to
manually enter the shutter speed.
Shutter Speed
�f the ��posure feature is to be manually configured, enter the
shutter speed settings.
Coax Gain
If the camera feed to the unit originates from the coax output
of the Oracle Dome camera, the �ideo signal can be boosted
by increasing the coa�ial gain setting. The default gain is 0 to
increase it select a �alue between 1 and 100 until the optimum
image quality is reached.
Coax Lift
If the camera feed to the unit originates from the coax output of
the Oracle Dome, the �ideo signal can be boosted by increasing
the coa�ial lift setting. Coa�ial lift differs from gain as only the
high frequency end of the �ideo signal spectrum is boosted, to
compensate for the greater attenuation of high frequencies in
coa� cables. The default gain is 0 to increase it select a �alue
between 1 and 100 until the optimum image quality is reached.
UT� �oost
�f the camera feed to the unit originates from the twisted pair
output of the camera. Two le�els of boost can be acti�ated to
impro�e image quality by compensating for losses in the cables.
