Wireless Doorbell By Jacob Jensen
If you want the best of the best, this unit is it. This is actually an upgrade from Jacob Jensen's original model doorbell, adding additional capacity and range. This attractive, modern doorbell unit will work at over 600 feet from the push button control, will work with multiple buttons, as well as allowing multiple chime units to be run off of one push button. A total of 64 different personal codes prevent the unit from being confused with a neighbor's unit and the unit is designed to be either free-standing or hung on a wall.
While battery operated, there is an optional power adapter for those who prefer a permanent installation. In addition to the five installed, high-quality tones, you can download your own ring tones in MIDI format and install them with the enclosed software and USB cable. An onboard LED lights up when the unit sounds, as well as when the batteries are low.
