How do I know if my remote is RF or IR?
IR stands for Infared and means the remote must be pointed directly at the receiver. RF stands for Radio Frequency and means the remote is multi-directional. Just about every remote that comes with any piece of A/V equipment these days uses an IR based control system.
Can RF Remote go through walls?
RF remotes use specific radio frequencies, typically a license-free 2.4 GHz bandwidth, to transmit a signal to a receiving device. The signals are able to be sent through objects like walls and furniture, extending the remote’s range.
How do you program a RF remote control?
