Bests & Worsts Reviews from Amazon

I bought a set of four Westinghouse intercoms. Usually people buy intercoms because they have a large house and don't want to have to trapes all over it to communicate with other people. These Westinghouse intercoms (and I believe the same goes for the NOVI intercoms) require that all itercoms be on the same electrical circuit (that is, controlled by the same electrical breaker). So, if your kitchen, family room, master bedroom, and garage outlets are on different breakers in your main electrical control panel and you want to set up an intercom system, the Westinghouse system will not work for you. Intercoms are usually for large houses...large houses usually have more than one electrical circuit for outlets...hence, this product likely will not work for most people. I replaced the Westinghouse intercom system with one by another manufacturer called the WireFree Intercom Reporter...this is a four channel system and it works great...works either with batteries or transformer...it is independent of the electrical circuits.
