The IM5000 Intercom System by NuTone will allow you to keep in touch with anyone, anywhere in your home or office. The "All-Call" function will allow you to talk to all of the speakers throughout your home, and with selective call you can talk to only one spaeaker at a time if you choose. Furthermore, there is a monitor function, which is particularly useful for families with small children or elderly family members. This system can support up to twenty stations.
