You may also want to experiment with the angle of vision through the glass to minimize other reflections. See next

“IR Cut Filter control”
can be “On”, “Off” and “Automatic”. The cameras with IR Cut Filter, NC-213WF,
NC-217WF, NC-218WF, NC-316W, NC-316P, NC-316PW, have a feature that combines the excellent daytime
color of the NC-216W with the IR night vision performance of the NC-217W.
During the day, an optical “IR Cut filter” removes all IR light on the NC-316P, NC-316W, NC-316PW, NC-107WF,
NC-108WF, NC-213WF series. This makes the camera’s vision similar to a human eye which does not see IR
light, and therefore all colors appear vivid and natural to us. At night, the filter moves out of the optical path
to enable IR night vision. You can actually hear a muted click when this filter moves in or out. This happens
both during power-up and when light levels change between day & night.
For special applications there is also a setting that allows you to keep the IR filter fixed either in the on or off
position. The normal factory default is automatic and this is recommended. For best IR night vision please
refer to the next chapter about sunshade position. Clean lens cover glass also helps extend the range.
