The camera is equipped with a motorized IR filter. The 

mechanical IR filter is taken out of the optical path in low-light 

applications. 

The IR filter is controlled either:

–

via an alarm input, or

–

automatically, based on the observed light levels.

If Auto switching mode is selected, the camera automatically 

switches the filter depending on the observed light level. The 

switching level is programmable. 

When the auto mode is selected and the switching level is set 

to -15, certain borderline scene lighting conditions can cause 

the camera to switch back and forth between day and night 

modes. Set a different switching level to avoid this.
