UFODAP supposedly has about a hundred automatic cameras around the world, mostly in the US. You can buy the hardware. It's a pan-tilt-zoom camera under a plastic dome, with hardware that looks for moving objects in the sky, photographs, and tracks them. Analysis software recognizes birds and aircraft. If two sites connected to the same control program lock onto a target, they can triangulate. It's possible to use ADS-B data for filtering out known aircraft. The hardware is good enough to detect and track the International Space Station.

But they don't see to be catching much.

Incidentally, hobbyists have been flying triangular jet-powered high speed drones since at least 2017.[2] Watch the video. That would look like a UFO if it wasn't a clear day and the pilot wasn't making low passes. Many of the "flying triangles" are probably something like that.

Russia, Ukraine, and Iran all use something similar, in various sizes.

It's not flying saucers, it's weird orbs / spheres. There is volume of footage, and sufficient quality. I think we're past the point of "is it real" and more at "okay so what is this really and what is it doing".

If we could take Tier 1 reports from NUFORC, have tons of metrics available with sensor data, we can make a better guess.
