I have a wireless door bell at my home
On second thought, a wireless intercom would be a better choice, especially in the winter. We don't want to bundle up and walk back to the museum only to find some kid was whacking the button or someone wasn't that interested or whatever. Whereas an intercom would let us talk to them before schlepping over there.
