“How does infrared remote signal go through walls? The remote, used in a room with the receiver, sends signals to control the source feed (i.e. cable box) by IR signal. IR, as far as I know, has to be in direct line of sight. As everyone knows who has used a standard IR remote control for their TV, anything obstructing the IR beam and the signal is blocked. How does this remote get an IR signal from a room in the basement (with the receiver) to the transmitter and cable box a floor above and perhaps through walls as well?”

The remote room Receiver actually converts and sends the code back through the same electrical lines that the audio/video is sent to the Receiver on.
Sorry, there was a problem. Please try again later.Both boxes transmit information through your house's electric wires. One unit sends television signals from the cable box to your TV. The other unit has an infrared sensor and sends signals from your remote control (aimed at that IR receiver) to an infrared light you attach to the cable box. You attach one unit to your cable box and to the IR light bulb. You attach the other unit to your TV and to the IR sensor. You plug both units directly into electric wall outlets. Do not use power strips, surge protectors, or extension cords. You aim your remote control at the IR sensor and the signal is sent through your house's electric wiring and repeated directly into your cable box using an infrared light bulb you stick on the front..
Sorry, there was a problem. Please try again later.It has a Infrared repeater built into the box with sensors on the receiver and the transmitter. Your remote will work through that.
Sorry, there was a problem. Please try again later.Your are sending your IR to the receiver which is passing it to the transmitter. So the IR is transmitted over the power lines.
