The Vanco 280740 IR Receiver is an In-Wall Decora-Style infrared receiver for use with a home theater IR repeater system. Typically, this IR receiver is used in an installation where having the receiver match other Decora-style outlets and switches is of utmost importance. The IR receiver takes in a signal from your remote control, passes it through to a connecting block and out to emitters - allowing you to remotely control your AV components behind cabinet doors or in a closet. You can also use the receiver to replace an existing receiver in your home theater IR repeater system. 18 AWG 4 Conductor Low Voltage Wire (sold separately) is required for connection between the IR receiver and a connecting block. This version of the IR receiver is CFL proof, so you can install it anywhere in a room with CFL lighting.
