Face comparison detection.face.detected

Key fields

Device ident dependent: lite compare may be {} only; full payloads include faces, snapFace, candidates, ptzInfo, etc. (capability page table, including ptzInfo.presetNumber). Keys below are not on every device.

id、faces、snapFace、candidates、isDuplicateRemove、address、passerby、passerby.uid、ptzInfo

Notes

Standard pushes use capabilityEvent and this page’s msgType; some models may also use legacy msg_type—see device.capability.list and message query.

Subscribe to capabilityEvent in setMessageCallback. msgType is detection.face.detected. Channel-level (includes channelId). compose: e_std_imouSFaceCompa may report {}; e_std_imouAFaceCompa carries the full field set.

V2 capabilityEvent push payload (deviceId, outputData, etc.) follows Receive alarm messages; Common payload covers legacy iotEvent/desc only—do not mix with capability outputData.
