So I want to install an intercom in my new house. Since I'll install my desk/study on the 1st floor, I want to prevent Erzina from shouting her ass off when dinner's ready (har har). The thing is that I don't feel much like installing a classic system, mainly because of the wiring plus the fact that the send/receive units will have to be on a fixed place (on the wall for instance).
Any of you creative minds have an alternative? And no, walkie talkies aren't an option :p
