PersonDetection Event and eventData

[dougpierce]

I'm attempting to create a starter in automation for PersonDetection.  Unfortunately, the cameras think they see a person a lot, but it's incorrect.  Therefore, I'm trying to identify if the person has been "seen" for more than 5 seconds and if so, send a notification.  The part that I am struggling with is what "eventData" represents in this event.  I'm not sure what it's supposed to be and cannot find any documentation to figure this out.  Please help me with a link or something pointing to where this information is as it's not on the help page for that event.

starters:
    - type: device.event.PersonDetection # A person has been detected by the camera.
      device: Back Room camera - Back Room
      eventData: ???
      greaterThanOrEqualTo: 5 seconds

same issue by trying to count the number of person detected

starters:
    - type: device.event.PersonDetection # A person has been detected by the camera.
      device: Office - Office
      eventData: count
      greaterThanOrEqualTo: 2

the validation system answer : 

La combinaison de champs optionnels de la struct n'est pas éligible.
[count] n'est pas un champ avec état valide pour [PersonDetectionEvent]. Liste des chemins d'accès valides : [].

@nickfromgoogle could we have items of the eventData struct (FieldPath) ?
