I found that as long as my soffit is high enough (mine is about 10’) then they work fine mounted to the soffit even without modifying the pivot for the camera. I think the only time it is an issue is if your soffit is 10’ and you really want to have the camera pivoted high enough to get a lot of distance.
But it is ridiculous that Ring won’t fix this. I don’t know of any houses that have floodlights mounted on the wall. I’m sure they are out there, but my father’s house built in 1972, my first house built in 2000 and my current house built in 1994 along with all houses of anyone I have ever asked have floodlights that mount on the soffit.
