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.
Manufacturer | Model | Firmware Version |
HID | R Series (Requires HID BTSmart Module) | R8.10.2.7 |
HID | Signo Series | R10.0.9.1 |
