SIA Releases OSDP (Open Supervised Device Protocol) Standard Version 2.2.2

The new version of OSDP provides enhancements to the security industry’s ‘leading access control communications standard.’

SILVER SPRING, Md. – The Security Industry Association (SIA) has released version 2.2.2 of SIA Open Supervised Device Protocol (OSDP), an access control communications standard developed by SIA to “improve interoperability among access control and security products.”

SIA OSDP is an access control communications protocol standard maintained by SIA to “improve interoperability, add advanced functionalities and support an AES-128 encryption for security,” according to the SIA announcement.

In use by many leading manufacturers, the standard is “recommended for access control installations that require advanced security or will be used in government and other higher-security settings,” the announcement says.

Why SIA Releases OSDP Version 2.2.2

Maintained and developed by the SIA OSDP Technical Subcommittee, the Open Supervised Device Protocol was approved as an international standard by the International Electrotechnical Commission in 2020 and has been published as IEC 60839-11-The standard holds one active patent (US-7853789-B2).

Version 2.2.2 “resolves errors that had appeared in the short-lived 2.2.1 update and introduces proper supervised input states, addressing previous issues,” according to the SIA announcement. It can be purchased through the SIA online store at $50 for SIA members and $200 for nonmembers.

In 2020, SIA introduced SIA OSDP Verified, a comprehensive testing program that validates a device’s conformance to the SIA OSDP standard and related performance protocols.
