[Support]: Configuring loitering_time requires removing required_zones for some desired behaviors

[d-steve]

Describe the problem you are having

This is exactly what I wanted out of loitering_time:
#11136 (reply in thread)

... also one other thing to note, there is a new "loitering time" field that is added to zones. So maybe you will find that you want to use "events" (reviews) now, because you can make it an alert if a person loiters but a detection if the person just walks by. That way you get more information on the timeline of when an object was detected

Unfortunately, behavior after setting loitering_zone for my config was that snapshots (in frigate+ page) and detections only existed once loitering_time had been met.

Struggled a bit with getting this working as desired until I read more closely that loitering_time defines when an object was considered a part of the zone, as opposed to the object being in the zone and it determining when a detection or alert is defined.

The issue for me was that I had previously had required_zones set, and I had to remove required_zones from my config in certain sections after configuring loitering_time. Specifically:

• to get snapshots in the zone for durations < loitering_time, I had to remove required_zones for the camera's snapshots section.
• to get detections in the zone for durations < loitering_time, I had to remove required_zones for the camera's detections section.

These may be obvious and expected behavior, but it may cause some people with prior configs and perhaps (ahem) less than perfect reading comprehension to stumble. It can also create some more complicated configs if required_zones is necessary for other purposes.

Documenting this here in case other stumble on this. May not be necessary to document this unless others are stumbling on this.
