2N make a standalone access control unit that can be biometric, or keypad, or rfid, whatever you choose, and it has its own switch built in so it can connect to the lock and release it. Its a PoE device so it just needs a cat cable. As 2N make the DS2 for Control4, it can be supplied in the same colour/finish as the intercom if they have one
the ACU doesn't have a driver for C4 as they are typically standalone, but as it has an enhanced integration licence supplied as standard with it, you can create automation strings on the ACU to send http messages back to the C4 system if you want it to perform extra actions when an entry is granted or denied (lights on, camera pop on screen, make a noise etc)
