As I see it either give a clear notification + location or don't give them at all. Or - a third option - only notify for camps near your borders, that will limit the notification to what you want to know (and if sound was limited only to those it would be OK, although I would prefer a notification). I would be OK if no warning is given at all but if you bother to sound a horn and add a mark to the map give a notification so that I can zoom to it.
