My father -in-law has a new set of wireless intercom
that my brother-in-law has purchased to replace his old one. It does not have an outside intercom
but it has an additional unit at his bedroom upstairs. Sometime he complains that he couldn't figure out some of the features that the new set has. My Dad is an old school so anything that's a little complicated (for him), but easier for us, he doesn't like that. But anyhow, I think he is getting used to it as I don't hear him complain about it these days. If you are looking for an intercom system for your business, please check out the selection of intercoms
