BLC
Set an area for Backlight Compensation. Backlight Compensation is a function that achieves the brightness of a selected area to
optimal image level. This function is necessary when an auto iris lens tends to close quickly due to an intense light coming from
back of object in the area wished to view, resulting in the area is too dark and difficult to see. In this case, users may set the area
corresponding to the portion wished to see. The area size illustrations are roughly as follows. (Unavailable when exposure mode
is Manual)

HLC
High Light Compensation (HLC) is a function that suppresses intensified light sources in camera coverage so that image will
be free from disturbance of strong light and thus details like license plate under strong headlight can be recognized clearly.
(Unavailable when exposure mode is Manual)
●
Shutter Speed
Users can adjust preferred shutter speed ranging from the fastest 1/10000 second to the slowest 1/7.5 (1/6.25) second.
(Available when exposure mode is Shutter Priority or Manual)
●
Gain
This option allows user to control the gain value ranging from the lowest 0 to the highest 48. Larger the value, more
intensity of lights come into the camera and vice versa. (Available when exposure mode is Manual)
●
Digital WDR
It is intended to provide clear images even under backlight circumstances where intensity of illumination can vary
excessively, namely where there are both very bright and very dark areas simultaneously in the field of view. WDR enables
the capture and display of both bright and dark areas in the same frame, in a way that there are clear details in both areas, i.e.
bright areas are not saturated, and dark areas are not too dark.
