ONVIF discovery and media flow reasoning

Map a fictional ONVIF device through discovery, services, media and events. Use the supplied offline material to follow each stage.

Overview#

Lab class: Offline specification and synthetic trace

Objectives#

Separate WS Discovery from device/service operations.
Map SOAP service endpoints, authentication and profile dependent features.
Follow media configuration to RTSP/RTP transport.
Follow event subscription/delivery and optional MQTT handling.
Tie conformance to exact product and firmware, not a generic ONVIF label.

Procedure#

Select an invented device/client combination and record the exact ONVIF 26.06 namespaces plus an example conformance listing structure.
Draw discovery scope, multicast/broadcast boundary and post commissioning need.
List service endpoints and whether HTTPS identity is validated.
Select one read only capability/media profile exchange and document synthetic request/response namespaces and bounds without sending it.
Map the returned media URI to RTSP control, RTP/RTCP transport, codec/payload and credential exposure risk.
Map an event subscription's lease, filters, delivery, renewal, gaps and authentication.
Compare every observed feature with the exact profile requirements and conditional/optional status.
Record unsupported, vendor specific and ambiguous behaviour separately.

Safety boundaries#

Scope is limited to specification review and synthetic response fragments. Network discovery, device contact, configuration, PTZ, I/O, media retrieval, and product acceptance belong to the separately authorised commissioning process.

Evidence checklist#

ONVIF specification release, profile status, namespaces, and synthetic product roles pinned
Discovery and post discovery trust boundaries separated
Media URI, RTSP, RTP/RTCP, codec, and credential exposure path mapped
Subscription lease, renewal, duplicate, gap, and authentication behaviour documented
Conformance listing, implementation support, interoperability, and site acceptance treated as separate evidence
