Understanding How IR Mode (Black & White) Operates
SIEMENS DAY/NIGHT Dome CCDA1415-DN 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.
