Consider wall-mount access control readers that support the credentials your system uses, such as proximity cards at 125 kHz, smart credentials at 13.56 MHz, mobile credentials over Bluetooth, or PIN entry through a keypad. Multi-technology readers can support existing credentials while providing a path toward encrypted smart or mobile access, whereas keypad readers may help accommodate users who need code-based entry.

Wall-mount access control readers typically connect to an access control controller through wired communication protocols such as Open Supervised Device Protocol (OSDP) or Wiegand, with the controller validating credentials and operating the door hardware. Some readers also support Ethernet or Power over Ethernet (PoE), while keypad or standalone models may use built-in relays for direct door control, depending on the system design.

Plan power according to the reader type, with keypad models supporting 12 to 24 VAC or VDC and some IP readers using Power over Ethernet (PoE) or a separate supply. Plan wiring for the supported communication method, such as OSDP or Wiegand, and choose a compatible wall installation style, including mullion, single-gang, or surface mounting.

Compare the reader’s mounting style, credential options such as proximity, high-frequency smart cards, mobile credentials, or PIN entry, and communication methods such as Open Supervised Device Protocol (OSDP) or Wiegand. For indoor, outdoor, or high-security installations, also review the enclosure material and ingress rating, operating power, tamper features, keypad lighting, relay or door-control functions, and compatibility with the access control system.
