The Physical Security Interoperability Alliance (PSIA) is a global consortium of more than 65 physical security manufacturers and systems integrators focused on promoting interoperability of IP-enabled security devices and systems across the security ecosystem and beyond.

Under the guidance of its board of directors, the PSIA promotes and develops open specifications, relevant to networked physical security technology, across all industry segments including video, storage, analytics, intrusion, and access control.

PSIA supports license-free standards and specifications, which are vetted in an open and collaborative manner, to the industry as a whole. Three active working groups, PLAI, Area Control, and IPD develop these specifications.
