The Tau2 640 radiometric thermal imaging camera (I'm assuming it's 25/30Hz model), has an inbuilt buffer that allows you to capture up to 20 images, however as it stands, you cannot capture radiometric images without a special camera link breakout board and the SDK, which will set you back about $2500. We've got the same problem with our Tau2 640 and we don't really want to give FLIR any more of our money, for a product which should be usable out of the box!
