True Day/Night switching

The camera is equipped with a motorized IR filter. This
mechanical IR filter is taken out of the optical path in low-light
conditions.
The IR filter is controlled either:
–
–
If Auto switching mode is selected, the camera automatically
switches the filter depending on the observed light level. The
switching level is adjustable. (If the day to night 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.)
Note:
If IR illumination is used, the alarm interface provides a stable
switching control for the day/night function of the camera.
