This is a really smart suggestion. It might not necessarily be a “camera feature” in the sense of you actively set something on your camera, but it seems like it could work along with the Neighborhood Alerts that are already in use (“Reports of a structure fire in your area” are what I see a lot).
My only thoughts are that privacy may be a concern, or that false alarms are pushed in the event it’s a rural area and it’s animals moving about.
