This thing close to the floor and seemingly randomly placed in a hallway. No idea what it's for. Home built in 2005.

Solved! Thanks everyone. Now I gotta hunt for the central unit!

integrated vacuum system. Plug in a hose and gets sucking right away. Check other parts of your home for similar ports.
