Camera's are definitely everywhere. Recently a meteorite struck Belgium. Lot's of videos and around 200 people testified of seeing it.

The difference can be lots of things of course: densely populated, maybe seen from further away etc. But it's indeed peculiar that now in the smartphone age, we hardly see any UFO's on video, relative to how many camera's there are.
