Shutter: If enabled, this setting lets you set the shutter speed yourself (measured in fractions of a
second).
AGC: Set the Auto Gain Control limit here. The lower the AGC level, the lower the video signal and
the noise. However, the image will be darker under low-light condition with IR-off if you set up the
Iris to the maximum level.
Slow Shutter: This option can be switched on when Auto or 1/30 option is selected in the Shutter
field.
Brightness: Set the image brightness here.
Black Level: Set the Black level here.
WDR Settings: The Wide Dynamic Range (WDR) function provides clearer images when both of
the very bright and dark areas simultaneously appear on the camera view. There are four value
options: OFF, Low, Middle and High. Note that when WDR is ON, some parts of the image may
appear solarized. This is normal for WDR, and is not a camera malfunction.
Visibility Enhancement: (OFF/Low/Middle/High) Images in foggy or rain environments or in
environments with a very strong luminous intensity have a dynamic range that is significantly
lower than ordinary images. The user can use this Visibility Enhancement setting to "DEFOG" the
image if such "FOGGING" is an issue.
BLC Settings: Back Light Compensation (BLC) is used to make the subject appear clearer when it is
set against a bright background.
OFF: Select to switch Back Light Compensation functions off.
ON (BLC): This option is useful when the background of the subject is very bright and the
subject itself is dark. The BLC will measure the light of the image center and the lens iris will
automatically set for optimal image quality.
You can configure one area to apply the BLC function. Select ON (BLC), the setup buttons
appears (see image below). Select Low / Middle / High from the BLC Gain drop-down list. To
set up a BLC area, click the Edit Area button and then click on the blue color tab to turn your
mouse cursor into a blue pen. Move the cursor to the position on the right screen where you
want the BLC rectangle to start and then click. Move your cursor to the position (diagonally
opposing corner) where you want the BLC rectangle to end and then click. The blue area will
be applied with the BLC function.
