I am building my first unit.  I have the PF date camera.

I notice there is a lens directly below the main camera lens.  What is this?

Do I need to make a hole for it?

Thanks

The Owners Manual says it is part of the Auto-Focus system, the other part is above the lens.  I think the Auto-Focus only works when the subject is real close, otherwise the cam is apparently on "Infinity" (like a No Focus Camera is)

Sometimes I cut it out just for appearance (mostly for those cams I build for relatives, so they don't ask) but it really don't do anything unless the uppper Sensor is also cut out.  I also think any glass over the sensors will probably block the Sensor Beam anyway, at least, on another brand cam I have, it says it don't work thru a window.....

I don't worry about exposing these sensors and have never noticed a focus problem
