Figured out a better way to handle those tricky glass break sensor spots
For years, I would just stick them on the wall near a window and hope for the best. About six months ago, a job in an old brick building in Philly made me rethink it. The sound bounced around so much the first one kept giving false alarms. Now I use a small piece of foam tape to angle it slightly toward the glass, not the room. It made a huge difference on the next three installs. How do you guys deal with rooms that have weird acoustics?

My old boss had a rule about testing in empty rooms. He made us clap our hands hard near each sensor spot before finalizing the run. The reverb in a stripped condo once set off a motion detector from twenty feet away. @craig.olivia, your speaker idea is smarter, but that clapping trick does burn the weird echo spots into your memory. You start to hear a room differently after a while.

Love that foam tape trick. I had a similar problem in a big empty warehouse last year. The echo was insane. I ended up testing placement with a speaker playing breaking glass sounds from my phone. Found a sweet spot on the ceiling beam that worked. Your method sounds way simpler and faster.

Breaking glass sounds from your phone in a warehouse is a wild choice. That echo must have sounded like a full on crime scene. I can't get past the idea of someone walking in on you while glass is shattering from the ceiling. Your sweet spot must have been really good to make that worth it.
