Day/Night Functionality
Basler IP Camera 73
Finally, the IR Filter current Level parameter lets you see the current darkness level as measured
by the auto controls. Familiarizing yourself with how this value changes when the camera is viewing
a dark scene and when it is viewing a bright scene will help you determine where the switch level
should be set.
You can use the Day/Night tab in the Image Controls parameters group (see page 16) to set the IR
Filter Switch Level and IR Filter Wait Time parameters and to monitor the IR Filter Current Level
parameter.
The IR-Cut Filter Announce Feature
The IR-cut filter has a capability called the "announce feature". When the Output Pin Function
parameter on the Digital I/O tab (see page 45) is set to "IR Filter Announce", the announce feature
will be enabled. When the announce feature is enabled, the camera will "announce" the current
position of the IR-cut filter by setting the state of output pin 0:
 If the IR-cut filter is in the open position, output pin 0 will be set to active.
 If the IR-cut filter is in the closed position, output pin 0 will be set to inactive.
