IRIS MODE
Function:
Select the iris mode.
Options: M/A
-
(default) when the camera is still, users can
adjust the iris manually, and otherwise, when the
camera is under control of the joystick, the camera can
adjust the iris automatically
.
MANU -
Users can adjust the iris manually.
AUTO -
The camera can adjust the iris automatically.
BACKLIGHT
Function:
Turn on/off the backlight compensation feature.
A sharp contrast of brightness and darkness may arise
when a bright backlight is present. This usually leads to
a vaguely dark or even silhouetted image of a subject
under surveillance. Under such circumstances, the
backlight compensation can be used to achieve a
suitable exposure level so as to get a clear view of the
subject.
With backlight compensation, the camera becomes more
sensitive to the light level in the center of the picture,
and thus, enhances the image quality of the subjects in
this area.
Options:
ON -
enable the backlight compensation.
OFF -
(default) turn off the backlight compensation.
WB MODE
Function:
Select the white balance mode.
The PTZ cameras feature built-in sensors to measure the
current color temperature, and use an algorithm to
automatically process the image so that the final output
image may be close to what the human eyes see.
Under some particular situations, however, users can
also manually adjust the white balance parameters to
achieve what they consider to be the best-balanced
pictures.
