Yes, it is a Casio EX-F1 and they don't make them any more. The cheaper ones Casio came out with after the EX-F1 don't have nearly the quality or resolution of the EX-F1.
I've looked for one like it that will do higher FPS, but they get WAY expensive.
Using the 1200fps is tricky, mostly because of the narrow 336x96 resolution, there are some tricks to dealing with getting enough light.
600fps is the sweet spot for firearms, 300fps barely slows them down enough.

this is one of my favs, it caught a 7.62x54r slug in flight on its way to shattering a cinder block
