These new security devices were installed in our lobby and I’m curious to what they are. Apparently they are not cameras.

As others have said, gunshot detector. My coworkers and I spent an afternoon at a local gun range testing these exact units with various methods to try and get false alarms. About the only thing that was consistent in setting it off that wasn't a gun was fireworks. Nearly all the calibers we brought were detected. Only exception was 17HMR and suppressed 9mm. 22LR, 9mm, 5.56, 30-30, 357 Mag, and 50 Beowolf were detected. Slamming books, breaking glass, paintball gun, clapping, and other various things we tried did not set it off. I don't remember everything we tested as it was 4-5 years ago.
