I know this is cheap but I just and went and bought a wireless intercom from radio shack. Works great. Runs off ac. I took a small wood box and then shoved the guts from the intercom in the box and hung it on the wall in my track room. Looks pretty damn cool, better than the plastic off white housing. Works like a champ.
