Mode
A digital camera needs to find reference color temperature, which is a way of measuring the color of a
light source, for calculating all the other colors. The unit for measuring this ratio is in degree Kelvin
(K). You can select one of the White Balance Control modes according to the installation condition.
The following table shows the color temperature of some light sources.

XDR Function: SHADOW FIGHTER XDR
The Shadow Fighter XDR is especially effective in solving indoor and outdoor contrast issues to
enhance better image quality and video display. It enables the Dome Camera to catch detailed data
from the dark part (Indoor) without any saturation from the bright part (Outdoor).
NOTE:
The Backlight function will be turned off automatically when the Shadow Fighter XDR is
enabled because the Shadow Fighter XDR has better effects than Backlight Compensation.
ON
Activate the Shadow Fighter function by selecting this option. In this mode, the Dome Camera
will operate the Shadow Fighter function automatically.
OFF
Deactivate the Shadow Fighter function.
Exit the XDR/Shadow Fighter menu and return to the MAIN PAGE to carry on setup of Privacy
Mask.
