Another What is it?

Inspecting Condo today and ran across this little white plastic cover located in both bedrooms and living room only, no other rooms had this. Located on wall about 8’ up.
There were smoke alarms installed, there are sprinklers through out and also a security system in place, no information was on the white plastic cover. client was asking?

Out of focus.


glass break sensor.

IDK lousy camera?

It lacks enough detail to see what the heck it is.

Thank You

Apparently Not.

I was referring to the upper left hand corner of you pic.

I’d guess part of the security system, maybe a motion sensor. Not sure why it would be in the bedrooms though.
