Using this IR repeater kit, you can extend your IR signal through an HDMI cable up to 300 feet. You can conveniently control source devices hidden away in cabinets or closets, or even in separate rooms.
The transmitter plugs into one of the adapters, which is connected to your source device. The receiver plugs into the second adapter, which is connected to your TV or display. A single HDMI cable connects the two adapters.
