Mode
•
Day
Day mode is permanently active.
The built-in infrared (IR) cut filter is always engaged (ICR OFF).
•
Automatic
(Day/Night switching)
The automatic Day/Night switching depends on the amount of visible light and internal
defined parameters. In low light conditions, the infrared (IR) cut filter is automatically
removed (ICR ON, night mode), which significantly enhances the sensor’s sensitivity for
near infrared light.
Depending on the amount of visible light, the IR cut filter is automatically engaged (ICR
OFF) and the camera switches back to day mode again.
•
Night
Night mode is permanently active.
The built-in infrared (IR) cut filter is always removed (ICR ON).
Threshold level
This setting provides the manual fine adjustment of the Day/Night switching threshold
levels (threshold values of brightness and darkness)
Possible values: 0 – 28 (Default: 12)
Higher level:
The camera switches earlier to night mode (ICR ON) and later to day mode (ICR OFF).
Lower level:
The camera switches later to night mode (ICR ON) and earlier to day mode (ICR OFF).
