A camera replays the current state of every property topic as PropertyOperation=Initialized whenever a pull-point subscription is created. dispatchEvent looked only at Kind and State, so any motion property that happened to be active at that moment counted as a fresh trigger — meaning every reconnect restarts a recording, and a flapping subscription manufactures motion with no motion. Observed on a camera whose pull-point was being recreated every ~18s: each recreate replayed ~90 property events, and once real motion made the VMD property active the replays kept re-triggering it. Rejects Initialized specifically rather than accepting only Changed. PropertyOperation is optional per WS-Notification and absent on many non-property events, which decode reports as PropertyUnknown; those are real events and must still trigger.
