IR Control

A universal IR remote is a remote control that can be programmed to operate various brands of one or more types of consumer electronics devices.

IR remotes are "line of sight" meaning you need to be able to point the remote at the equipment for it to work.

Low-end universal remotes can only control a set number of devices determined by their manufacturer, while mid- and high-end universal remotes allow the user to program in new control codes to the remote.

Many remotes sold with various electronic devices include universal remote capabilities for other types of devices, which allow the remote to control other devices beyond the device it came with. For example, a VCR remote may be programmed to operate various brands of televisions.

Because programming a universal remote can be a fairly complex procedure, it is most often performed by CHTI technicians, although non-technical users can often operate the remote after it has been programmed.
