The Bell that knocks...
Designer of house (not home) electronics, and creator of the noted designer smoke alarm, Jacob Jensen now has a unique design for a cordless doorbell. "The new, cordless Doorbell by Jacob Jensen is more than just an unique design of an often overlooked article for every-day use. It also features technical details such as a recording of the designer himself knocking on the door. The Doorbell features five different, specially composed, high quality polyphonic tunes. Additionally, it offers a special tune designed for the hard-of-hearing.". That would be the loud one... A single chime can be activated with an unlimited number of bell triggers within a 150 meter radius of the chime.
