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 domes 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.
Options:
AUTO -
(default) enable the camera to automatically
make white balance.
MANU -
allow a user to manually adjust white balance
parameters (see below).
WB-R
Function:

000 ~ 255 -
The color shift will be viewed on the
monitor when changing the R-gain value. The greater
the number is, the more reddish the picture becomes.
WB-B
Function:
Permit manual adjustment of B-gain value for customer
white balance.
Options: 000 ~ 255 -
The color shift will be viewed on the monitor
when changing the B-gain value. The greater the number
is, the more bluish the picture becomes.
FOCUS MODE
Function:
Select the focus mode of the camera.
Options: AUTO -
(default) enable the camera to automatically
focus on the subject in the center of the picture.

when the camera is still, users can adjust the
focus manually, and otherwise, when the camera is
under control of the joystick, the camera can adjust its
focus automatically
.

target stays at the following conditions:
z
is not in the center of the image;
z
appears too dark or vague;
z
is a strong light object, e.g., a flash light;
z
is a large blank area such as a white wall;
z
is located behind a screen-like object such as a painted glass
window or a safety net;
z
moves too fast.
4.5 Setting AE (Automatic Exposure) Mode

(Automatic Exposure) mode to have the camera automatically set
the shutter speed and/or aperture value to match the brightness of
the scene. Digital Slow Shutter (DSS) can also be set in this menu.
