Optical Zoom Limit
Select to limit the Oracle Domes optical zoom function. By default
‘100x’ is selected and the camera can zoom to its maximum
capabilities. The optical zoom function can be limited to between
75% and 100% magnification.
ICR
Oracle Domes with day/night cameras have an Infrared Cut
Removal (ICR) function which can enhance the camera’s
sensitivity in low light conditions as well as allowing infrared
illumination to be used (infrared is blocked by the IR cut filter).
When ICR is ON, the camera switches to monochrome mode, the
IR cut filter is removed and the camera is at its most sensitive.
The default setting for the camera is AUTO ICR 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 ICR to OFF, or can be forced into mono
with maximum low light sensitivity by setting ICR to ON.
Alternatively ICR 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 ICR. This method
can be used to avoid instability that may occur when the camera
controls the ICR switching in marginally low light conditions.
Removing the IR cut filter due to low light can cause enough of an
increase in scene brightness and video level to make the camera
return the IR cut filter and switch immediately back to colour mode
(at which point the video level drops and the process is repeated).
White Balance
The Oracle Domes White Balance feature enables the camera to
compensate for different lighting scenarios which can effect the
colour quality of the displayed image. Select ‘Auto’ for the camera
to auto-compensate for white balance depending on current view.
Select ‘Indoor’ to permanently set for best results in an indoor
setting. Select ‘Outdoor’ to permanently set for best results in an
outdoor setting.
Exposure
The Oracle Domes Exposure setting can be set to maintain
optimum contrast settings for the viewed image/camera location.
Select ‘Full Auto’ for the camera to auto-compensate for best
exposure settings depending on current view. Select ‘Manual’ to
manually configure exposure settings. Select ‘Shutter Priority’ to
manually enter the shutter speed.
Shutter Speed
If the Exposure 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 video signal can be boosted
by increasing the coaxial gain setting. The default gain is 0 to
increase it select a value 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 video signal can be boosted by increasing
the coaxial lift setting. Coaxial lift differs from gain as only the
high frequency end of the video signal spectrum is boosted, to
compensate for the greater attenuation of high frequencies in
coax cables. The default gain is 0 to increase it select a value
between 1 and 100 until the optimum image quality is reached.
UTP Boost
If the camera feed to the unit originates from the twisted pair
output of the camera. Two levels of boost can be activated to
improve image quality by compensating for losses in the cables.
