Found a smarter way to mount motion sensors in garages last month
I was installing a system in a garage in Tucson last month and kept getting false triggers from the heat. After three service calls the homeowner was frustrated. I switched to using a ceiling corner mount with a pet-immune sensor angled away from the furnace. It cost me about 40 bucks extra per sensor but the false alarms stopped completely. Has anyone else tried a different mounting position to beat heat issues in garages?

Duct tape a piece of aluminum foil on the wall behind the sensor facing the furnace. Seriously, it reflects the infrared heat away from the PIR element. Did that in a Phoenix garage where the furnace was right next to the sensor and it cut false triggers down to almost zero without having to move anything. Cost me maybe 50 cents per install.

Yeah did the same thing in my buddy's garage. Worked like a charm. Cheap fix.
