Ive got a scenario where setting up a visor control transmitter to activate a away scene, close garage, and arm alarm is desired. My concern is how secure is the signal being transmitted to the VCRX? I know garage door openers have a rolling code system that make it hard to "listen in" and snatch a RF signal that you can duplicate. Whats the setup with the Visor control? Anyone from lutron tech support chime in on this? Thanks
