6.2 Day/Night switching

The camera is equipped with a motorized IR filter. The

mechanical IR filter can be removed in low-light or IR

illuminated applications by software configuration settings.

If Auto switching mode is selected, the camera automatically

switches the filter depending on the observed light level. The

switching level is programmable. In Auto switching mode the

camera prioritizes motion (the camera gives sharp images

without motion blur as long as the light level permits) or color

(the camera gives color pictures as long as the light level

permits). The camera recognizes IR illuminated scenes to

prevent unwanted switching to color mode.

There are four different methods of controlling the IR filter:

– via an alarm input,

– automatically, based on the observed light levels, or

– as part of the programmable mode profile.
