IR CUT FILTER
The camera have two modes of operation: color, and black-white. You can increase sensitivity in
low light conditions by switching to black-white mode (removing the IR cut filter). Color mode is
preferred in normal lighting conditions.
The following are the settings for the IR cut filter:
OFF Manual operation is controlled by preset 88 (filter IN) and 89 (filter OUT).
AUTO (default) Automatic operation is controlled by the auto IR level setting.
YES Images are always displayed in color mode.
NO Images are always displayed in black-white mode.
Low Light Focus
If you are using an IR illuminator, the low light focus feature of the camera can be tuned to
correspond to the setting of the illuminator.
There are three low light focus settings:
OFF (default) Low light focus is not activated.
850NM Low light focus is tuned to 850 nm (nanometers).
950NM Low light focus is tuned to 950 nm.
Auto IR Level
The auto IR level is the light level at which the infrared filter switches IN or OUT.
Following are the available settings for the auto IR level:
DUSK (default) approximately 6 lux (black-white)
approximately 13 lux (color)
DARK approximately 0.1 lux (black-white)
approximately 2 lux (color)
NOTES:
• If backlight compensation is ON and the IR cut filter switches OUT in normal lighting
conditions, adjust the Auto IR Level to a darker setting. Refer to the Backlight Compensation
(BLC) section on page 36.
• Low light does not mean no light. Some type of illumination is required (street light, IR light,
etc.). The camera is not sensitive to IR light when the IR cut filter is IN.
