Hello,
I have the Home hub connected to 4 camera's and I noticed that there is a difference in detection of events between the events stored on the camera and the events stored in the home hub.
One can choose the storage source to view the events by clicking on the small icon in the replay line.
I notice that the events on the camera always start 8 seconds earlier and I also encountered once that there was an event in the camera, but not in the Home hub.
Probably the event detection takes place independently in the camera and the home hub.

If I remember there was a pre-trigger time parameter when I used the camera's without the hub, and this parameter I cannot find in the home hub.
Does anyone recognise this behaviour?
