Shenzhen Kelvin 4-Channel Universal RF Remote Control Duplicator suitable for gates, garage door openers, barriers, home security systems, etc.
This gadget operates at 433.92MHz frequency (IMPORTANT: leave us a message along with order if you want 315MHz or other frequency), capable of copying most fixed code or learning code RF remote controls face to face, so you will always have a backup remote control.
Please note that the frequency band 286MHz to 400MHz can't be used in the EU, which means you're likely to use a 433.92MHz / 418MHz / 868MHz remote control if you are in the EU.
