That job at a school gym changed how I mount motion detectors

I had this install at a middle school gym last spring. Big open space, high ceiling like 30 feet. I put the motion detectors where I always put them, on the side walls spaced out. But the janitor told me the basketball hoops swing and move around and the kids bounce balls off everything. Well two weeks later I get a call because alarms keep tripping at night. Turns out the hanging scoreboard was casting shadows and the swinging basketball nets were setting off false alarms from the motion. Now I always sketch out the room layout first and ask about anything that moves. Has anyone else had false alarm issues from weird stuff like ceiling fans or banners hanging down?

Man that scoreboard shadow thing is such a pain, totally feel your frustration there.

Pretty sure that shadow glitch only happens on the older firmware versions though.
