Connect a 3rd Party Reader to a Verkada Access Controller with OSDP

Connect 3rd party readers to Verkada access controllers using OSDP v2.2

Updated yesterday

You can connect a third-party reader to any Verkada ACU via RS-485 using OSDP v2.2 for improved data integrity. All Verkada ACUs fully support third-party OSDP readers.

Alternatively, third-party readers that only support Wiegand can be connected using the ACU’s Wiegand reader ports. See Wire a Door to a Verkada Access Controller for more information.

OSDP communication between Verkada ACUs and third-party readers is not encrypted. However, all Verkada readers support fully encrypted communication with Verkada ACUs.


Configuration

  • Readers must be set to channel address 0

  • Communication baud rate must be set to 38400

  • Wires must be terminated into A-B of a given door port

The following are common equivalent naming conventions:

  • A, White, A+, TX+, HID-GPIO1, HID-Red/Green

  • B, Green, B-, TX-, HID-GPIO2, HID-Tan

Optional settings

These settings should be configured if available:

  • Setup mode ON

  • Encryption enforcement OFF

LED feedback is red for access rejected and green for access granted. When idle, the reader displays white if supported. These colors cannot be changed.


Compatibility

Only readers that can be configured to address 0 and baud rate 38400 directly from the reader or its manufacturer's management interface are supported.

The following reader models and firmware have been verified for OSDP communication with Verkada ACUs. Contact Verkada Support for compatibility options if your reader is not listed.
