Wired gate access controllers use existing Ethernet cabling for network communication and can be a practical choice when network drops are already available near the gate. Wireless gate access controllers use a wireless connection, which can help on projects without network cabling by reducing the need for trenching and new cable runs, while still supporting gate access control in exposed areas.

A gate access controller should support OSDP and Wiegand reader protocols to accommodate common reader connections and deployment requirements. Ethernet, Wi-Fi, or Power over Ethernet (PoE) connectivity can help link the controller to the access control network, while relay outputs provide control of gate operators.

Gate access controllers connect to gate operators, electric locks, and similar hardware through configurable relay outputs that send the open, close, or unlock command. Depending on the controller, the system may communicate over Ethernet, Wi-Fi, or Power over Ethernet (PoE), while OSDP or Wiegand connections support compatible readers and access devices.

When specifying gate access controllers, evaluate support for Power over Ethernet (PoE), a low-voltage transformer, or optional PoE++, along with Ethernet or Wi-Fi connectivity to match the site’s wiring. Battery monitoring can help technicians track backup power status, while OSDP or Wiegand support may help connect readers and other access devices.
