ONVIF has started open discussion with several international standardization organizations. On June 3, 2014, the Security Industry Association (SIA) and ONVIF signed a Memorandum of Understanding toward the further development of IP-based interoperability standards in access control. As part of the relationship, ONVIF will provide support to SIA & OSDP IP extension initiative, while SIA will provide education to its membership and industry stakeholders of Profile C and other ONVIF PACS (physical access control system) activities. Each group will appoint an official representative to liaise with the other group for the purposes of increased information sharing and collaboration. ONVIF has established liaisons with ISO JTC1 HEVC, also known as H.265 and IEC Technical Committee 79, Alarm and electronic security systems. ONVIF is currently referred to in the international standards IEC62676 Video Security Systems, IEC IEC62580-2 CCTV in trains, and in the ongoing work in IEC TC79 WG 11, Electronic access control systems which has produced a new International Electronic Access Control standard, IEC 60839.
