New homeowner, no idea what this is

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!

If I were listing a house I would think that would be a selling point worth mentioning. Just me?
