PSIA (Physical Security Interoperability Alliance) is an industry group formed to create interoperability standards between physical security devices such as IP cameras, video recorders, and access control equipment, and also the name of its specification. It defined device discovery, configuration, video streaming, and event delivery through a REST-style HTTP API, and competed with ONVIF, which appeared around the same time. Today ONVIF has become the de facto standard in the network camera field, and PSIA is supported only by some devices.
