PSA: I've been mounting motion sensors upside down for 8 years

I was at a job site in Austin last month and the homeowner had their own DSC system from before I came along. He pointed out that his sensors have a little arrow on the back that says 'this side up' and I went wait, what. I'd always just slapped them on the wall however they looked straight. Now I'm wondering if half my customers' false alarms were actually my fault. Has anyone else figured out they've been doing a basic install step backwards for years?

Guess that arrow was tryna tell us something we were too busy to read.

That arrow thing got me too. Took me six years to find the right mounting bracket size.
