I work with thermal imaging cameras. The rules are very specific on what can be exported, but it's not a blanket ban. I've asked FLIR for CAD documents before and they just sent them. The actual technology inside the systems is very hush hush though, very difficult to find anything publicly.
Basically anything below 9fps is fine to send anywhere except countries on the USA naughty list.
Anything above that can be exported with minimal effort to countries on the USA "nice" list (called STA). If you're in a non "terrorist" country, but not in the friendly group you can apply for an export license which isn't particularly onerous.
There are specific exceptions for high resolution cameras, high speed cameras, cooled options and so on. That's not to say you can't export them, but you need additional clearance.
