Think, what if you want to control a device that hasn't any built-in infrared receiving functionality. Fortunately, you can do this by using an infrared socket. An infrared socket is a pluggable device that can be plugged into a electrical wall socket. Then, you can plug your electrical device into it. In addition, the IR Socket has a simple IR receiving unit, and you can attach it to a place where the IR signal can be received properly.
