OFF) to be modified in the menu. Note that this can be set up only if
DAY&NIGHT is set to COLOR mode.
DWDR menu:
Digital wide dynamic range ( DWDR ) allows you to see details of objects in
shadows or details of objects in bright areas that have high contrast between
light and dark areas. An example is the headlights of a passing car.
Low level: Set the low level of DWDR. The values range from 0 to 15

BLC (backlight compensation) can improve image quality when the background
illumination is high. It prevents the object in the center from appearing too dark.
