PC Protection for Motion Sensors?

[stueck0514]

Hey guys, I am trying to set up some protection for my motion sensors.

Currently I have 6 in one room. How can I go about protecting the motion sensors? I put some bulletproof glass up, but they cannot see through it. Am I stuck with railings or something?

I would say bars, and make them fit all around it. Maybe with a hatch on top for easily reparing. Or arrow slits, that might work aswell

It depends on how much FOV you want for the them, I use an arrow slit in some cases.

We use bars as well.
