> as cameras with frame rates higher than (I believe) 1M fps are ITAR controlled. I'm curious what's the reason for that. I can understand that extremely high

  The UK government has a great website for this, where you can look up restricted things and the reason for the restriction. Search for "frames". Mostly it's because they're used for ballistics and weapons imaging. They're listed under item 6A003 (broadly, cameras) on the export list which includes: - Cinema cameras with frame rates more than 13,150fps - Mechanical/electronic cameras with frame rates more than 1M fps - Frame readout speeds of more than 125 fps full frame. The last one is interesting, you can buy machine vision cameras with higher frame rates fairly easily, so perhaps it's only something to worry about if you're traveling. https://www.ecochecker.trade.gov.uk/spirefox5live/fox/spire/ https://www.ecochecker.trade.gov.uk/spirefox5live/fox/spire/
