decide that it is daytime and switch the filter to the day position. This parameter helps to keep the
auto controls from mistakenly sensing a momentary change in lighting conditions as a change from
night to day or from day to night.
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
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", i.e., the camera can "announce" the
current position of the IR-cut filter by setting the state of one of the cameras I/O ports:
If the IR-cut filter is in the night position, the port will be set to active.

If the IR-cut filter is in the day position, the port will be set to inactive.

For the IR-cut filter announce feature to work correctly, the direction on one of the camera's I/O ports
must be set to "output", and the port's function must be set to "IR Filter Announce". See Section 3.9
on page 57 for more information about setting the camera's I/O ports.
