"Our cameras in Northford, Connecticut, and Douglassville, Pennsylvania, as well as a doorbell camera in Wayne, New Jersey, captured the meteor, and from that we measured its trajectory... The path traced back to low in the asteroid belt."
I don't doubt it, but that's an astounding trajectory estimation...
This is absolutely trivial as long as any fixed ground objects are visible in a camera and does not at all require some sub-pixel precision.
Desert Fireball Network, and less public precursor projects have been doing this for a while now:
