Motorized window treatments are operated by a motor responding to either radio frequency or infrared signals. Those signals are controlled by a wall switch, remote control, or a computer. Although motorized window treatments have been around for decades, they are just now reaching popular appeal.
Convenience is certainly one reason for their attractiveness. Structures built today are known for their vast use of glass and it can be tedious to walk from window to window to raise, lower or tilt window treatments. Instead one controller (wall switch, remote, or computer) can operate a single or a group of treatments with the press of a button.
