What is the difference between an IR and an RF remote control?

< All Topics

The IR remote is an InfraRed remote.  Infrared is based on the “light” part of the electromagnetic spectrum. The RF remote is a Radio Frequency remote.  Radio frequency is based on the “radio” section of the electromagnetic spectrum. While the IR remote control requires direct aim to the receiver in order for the signal to be received, the RF remote control can be pointed in any direction to function as long as the signal is within range
