I was wondering if any of you have any recommendations for a wireless push button for wiring to an input on a mercury board for a receptionist to unlock a door. The customer is wanting something semi mobile. We had another customer that had a Linear DXR-701 receiver and button. Seemed to work ok, but they are tough to find, and seems like they are mostly meant for garage doors. Not sure if that's acceptable or not.
Is there anything that is encrypted?
