The thermal infrared camera detects the long wave infrared radiation of warm bodies. It shows real differences in temperature by tagging them with different colors. Besides being very expensive, unless there is a big fire underneath, there is no reason to think that the smoke in the air would be a significantly different temperature than the rest of the air so I think it would not be doing a thing. A standard infrared camera looks at the short wave infrared, which is not emitted by most objects around room temperature. Instead relies on an infrared source that is invisible to the naked eye but is visible to the camera. mostly used for discreet surveillance. Infrared light with a wavelength longer than visible light, perhaps less likely to smoke, given the small size of smoke particles. Light by smoke looks reddish because the longer red wavelengths are scattered less by the smoke. Blue and violet light are spreading through smoke, why is smoking in the sunlight looks blue. So if you want to smoke a good look, I would a regular camera to get and set a blue filter on it (maybe change the final picture to black and white so it does not look funny). Also, some cameras have a built-in UV-blocking filter into them. A Part of the purpose of this is because UV is scattered by the atmosphere so much (stuff like smoke) that the images tend to look more blurry without a UV blocker. If your camera has this built in, remove the UV-blocking filter and you should see even more smoke. If you control the lighting, make heavy use of blue light.
