Wireless Intercom System

LiftMaster Wireless Intercoms take communication to a whole new level. They make communication easy - whether you are inside or outside your home or business - and are the first and only intercoms in the world designed to operate from batteries full time. This means that they are are always on and available and conserve battery power when not in use, delivering years of uninterrupted service. They are also the only expandable wireless intercoms available to enhance your home and business communication to multiple locations. And because all our intercoms are wireless, installation costs are minimal - no expensive wires, no excavation and therefore simple to install.
