I'll really appreciate anyone of you here who has experience on this.
I was on the internet searching for a Card reader that has already a auxiliary relay output NC and NO. What could be the reason I couldnt find one. All are in wiegand output to controller then controller to discrete output (1, 0)
Anyone of you here already designed a system once-in your home?
I opt to discard actually the controller if card reader has already contact output on it. I just design instead a low cost relay interfaced for the doors locks.
