Meet the X10 Powermid IR Remote Set: a smart product that lets you remote control your A/V equipment from a different room. Its IR signals travel up to 100 feet through walls. The device works with any IR remote controlled A/V component. With this device, you will be able to control TVs, cable boxes, DVD players, stereo equipment and other IR remote controlled devices from a different room.
The device consists of a transmitter and a receiver. Here is how it works: when you use your remote, the transmitter receives the IR signal, converts it into an RF signal, and wirelessly transmits the signal to the receiver, which sends it to the A/V component. The device is available for under $60 at this time.
