Another one is thermal vision cameras. Anything above 9fps (I guess an arbitrary cutoff to do with night-vision goggles) is export controlled. This is despite the technology being very valuable for many industrial and hobby applications.

If that was a guesstimate on frame rate it's likely off.

Regardless of US controls, I can from Australia buy a high quality 50 fps thermal scope with built in 1000m (or ~ 1000 yard) laser range finder from Hangzhou, China.

ie. Why lock the stable at 9 fps when out on the open plain 50 fps is already running free.
