7.3 True Day/Night switching
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.
Note:
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.
