Finally learned how to stop motion sensors from false alarms in hallways after way too many repeat visits.

Angle them slightly downward so they only see the lower half of the hallway. I mean, the main thing for me was pets and air currents from vents, so this helped a ton. I also moved mine higher up on the wall, like seven feet, and pointed them in a more vertical line. Then I just walked by a bunch of times to test the new detection pattern. That finally fixed the false alarms from our cat and the AC kicking on.

Actually, angling them down too much can miss important coverage at chest height. @tessap97's tip on mounting height is solid, but the angle part is a bit tricky if you still need to catch a person walking. You really just want to avoid pointing it directly at the vent or a sunny window.
