I finally saw what a 20 degree panel tilt does after 6 months in Tucson
Pulled a motion sensor off a wall in Tucson last week that I mounted flat back in March, and the thing was caked with dust on top while the one I tilted 20 degrees stayed mostly clear. Same room, same install, 6 months apart. Half of me says tilt every PIR from now on and the other half says it's one job and I'm overthinking it. What's the actual rule you guys follow on tilt angle for dusty spots?
