Access controllers
Access controllers receive a credential from a card reader or keypad, check it against permissions, and release the door lock.
Selection depends on the number of doors a single controller manages, the reader interface it accepts (Wiegand or the more secure OSDP), and whether it operates standalone or networked over TCP/IP to central access-control software. Standalone controllers suit single doors; networked panels scale to multi-door sites with centralised logging.
- Door count — single-door units for one entry, multi-door panels for buildings with several controlled points
- Reader interface — Wiegand for legacy readers, OSDP for encrypted reader communication
- Network connection — standalone for a single door, TCP/IP for centralised multi-site management
