Unknown Device- What is this?

I see these devices in my school (Simplex alarms) and in a few other buildings (all school-related).

I’m thinking it is some sort of surveillance camera. It could be a security motion sensor, but there are already some in the area as well.

Does anyone know what this is? Any comments would be appreciated.

Occupancy sensor. Connected to a relay which typically controls lights but can do just about anything.

After X ammount of minutes with no detected occupancy it will shut down whatever load it controls.

Makes sense. Thanks a lot! :stuck_out_tongue:

You thought it was a camera? :slight_smile: How does it make sense?

Because an occupancy sensor makes more sense than a hidden camera. :wink:

That looks a lot like the speaker on the burglar alarm at the home depots. Maybe the same company makes them?

Nope. Not even close.

Those are shoplifting alarms by the way…
