In general, thermal cameras operating at 60 fps and/or 30 fps (NTSC) or 50 / 25 fps (PAL) video rates are export-controlled by the U.S. government.

The FLIR OEM camera modules - including Tau2 640 (both 60 and 30 fps), Tau2 336 — are classified as dual-use items and require export licenses from the U.S. Department of Commerce.

The FLIR Vue and Vue Pro (640 and 336) are also dual-use.

Boson 640 (60/30 fps) and Boson 320, are controlled to the ITAR, and require export licenses from the U.S. Department of State prior to delivery outside of the U.S. or Canada.

The U.S. government allows thermal cameras with frame rates less that 9 fps to be exported without a license. This is why FLIR offers thermal cameras with "fast video" and "slow video" options.

NEdT (noise equivalent differential temperature) is the key figure of merit which is used to qualify midwave (MWIR) and longwave (LWIR) infrared cameras.  It is a signal-to-noise figure which represents the temperature difference which would produce a signal equal to the camera’s temporal noise.  It therefore represents approximately the minimum temperature difference which the camera can resolve.  It is calculated by dividing the temporal noise by the response per degree (responsivity) and is usually expressed in units of milliKelvins.  The value is a function of the camera’s f/number, its integration time, and the temperature at which the measurement is made.
