This may not explain what's happening to you, but Google Nest's cameras have a built-in, non-configurable "cooldown" period after an event occurs. So, our cameras and doorbells may not flag a half-dozen events and send a half-dozen notifications in a 5 or 10-minute period just because we walked in front of the camera a half-dozen times in that time period. All of the events will be recorded if you have a Nest Aware Plus subscription with 24/7 history, but only the first event may be flagged as a detected event.
A year or two ago, a Google Nest Community Specialist posted a chart in this forum of the "cooldown" periods for each camera, varying by type of event and type of subscription, but the post was deleted shortly thereafter.
