ONVIF

ONVIF defines standardised interfaces and profiles intended to improve interoperability between IP-based physical-security devices and clients. A product is not generically ONVIF compatible: conformance is tied to a claimed profile and specific firmware or software version listed in the official conformant-products database. Different profiles cover different feature sets, so two conformant products may still lack the same required function. Procurement should identify streams, events, analytics, access-control or configuration capabilities needed and verify both device and client declarations. Network, credentials, codecs and vendor implementation still affect integration. Testing should use the exact versions and required workflows, including discovery, live video, events, recording and failure recovery. A logo or successful connection alone is not evidence of complete interoperability.
