Detecting Fights In Prison Bathrooms: How Would You Do It?

Actual application question we received: a medium security prison is having incidents in their bathrooms, mostly fights in the shower area. They cannot put cameras in the room, more or less (it's possible but very touchy and requires a lot of paperwork and regulation).

They can put a camera outside the room facing the door, which looks similar to below, which would get them good video of who is entering/exiting. They can shoot through the doorway and window as well, since those areas are technically outside of the shower/toilet areas. But they would be so obscured I don't think video would be the most useful thing here.

There is also discussion of doing audio analytics/alarms, like the Louroe Aggression Detector. I thought it may be worth putting a PIR in the room as well to notify when it was actually occupied, so the VMS (Genetec) could switch views and guards could be more aware.

Thoughts on this approach/approaches? Any other ideas?
