Understanding How IR (Black & White) Mode Operates
SpeedDome Ultra VII Day/Night provides a black-and-white (B/W) mode to improve camera
performance when the light level falls below certain thresholds. This allows clear images to be
obtained under low-light conditions. This is referred to as IR Mode. There are five IR Mode settings:
Off, On, Auto High, Auto Mid and Auto Low. The following table lists the approximate lux values
when the camera is expected to switch between color and B/W modes. Actual values depend on the
current zoom setting of the camera and the light source.
