built-in infrared (IR) cut-filter which can be disengaged from the image path for increased
sensitivity in low light environments.
Select from AUTO, DAY and NIGHT
NIGHT: IR cut filter is always removed (ICR ON).
DAY: IR cut filter is always attached (ICR OFF).
AUTO: Auto Day/Night mode switch. The camera will automatically switch the settings
needed for attaching or removing the IR cut filter. At a certain level of darkness, the IR
cut-filter will be disabled and increase the infrared sensitivity (ICR ON). At a certain level
of brightness, the IR cut-filter will reactivate automatically (ICR OFF).
4.2.6. DIG. NOISE REDUCE
DIGITAL NOISE REDUCE (DNR) function reduces background noise under low light
conditions differently in different modes.
OFF: No noise reduction effect.
LOW: Noise reduction effect is small but there is little afterimage.
MIDDLE: Noise reduction effect is generally effective in this mode. Noise can be
reduced properly and the afterimage is not strong.
HIGH: Noise reduction effect is excellent but afterimage is also strong.
4.2.7. WIDE DYNAMIC RANGE
This function is effective when shooting images against the sun or any other bright light
source. When both bright and dark areas exist in an image, WDR allows both areas to be
seen clearly. In Wide Dynamic Range, we define wide dynamic range from LOW,
MIDDLE, HIGH and OFF.
OFF: Disable wide dynamic range.
