AUTO IR LEVEL
(Applies only to 24X and 35X models.)
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 section.
• Low light does not mean no light. Some type of illumination is required (street light, IR light, and so forth). The camera is not sensitive to IR
light when the IR cut filter is IN.
