IR CUT FILTER
Spectra III has two modes of operation: color, and black and white. You can increase sensitivity
in low light conditions by switching to black and 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.
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)
NOTE: 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
section.
NOTE: 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.
