looking around the place im finding it confusing what i need to make this work.
my setup is as follows.
i want to have 3 Wiegand rfid/keypad, one for each gate, i have 3 that are currently wired up with a rfid/keypad wiegand that goes to office.
i want to have different pin numbers for different people and also have rfid key tags for people as well all so i can identify if needed who accessed the gate and when.
what program does it work with on my pc??
also have a shed down the back and 2 doors that have keypads as well, not wired to front office but network available.
what hardware do i need for this set up??
