I don’t have the exact model to hand, but they are a super discrete little thing in the ceiling. I can get the exact model later if you want.
It does motion in 3 directions using infra red, and gives you light levels and temperature as well.
They can sense really damn far, and actually I had to turn most of them down in sensitivity to make them useful.
I use the same sensors for triggering the alarm system. They look way more attractive than those ugly corner sensors most security systems use.
- Ruthalas 7y agoI'd be interested in the model if you have the opportunity to check! Thank you.

You can see what one looks like in place here in the middle of this picture. I use black ones for my wood ceilings. https://i.imgur.com/pTCOKJx.png https://i.imgur.com/pTCOKJx.png On the left hand side is one of the air quality sensors.
