Info:
If using the camera together with
infrared illumination
, we recommend using
video lenses
with
special
IR coating
to prevent a physically based focus-shift between daylight and IR illumination.
We recommend using the
D/N mode “MANUAL”
when the camera is used with discrete IR
illumination in order to prevent the continual switching between color and B/W mode that might occur
with the D/N mode “AUTO”
