Absolutely agree. The confusion on this probably stems from thermopiles (which are kind of single pixel thermal cameras) and higher res thermal cameras. If you think of it as the same an ambient light sensor vs an optical camera then the divisions become clearer. There are very low pixel count thermal cameras that blur the boundaries though so I guess you may have one of those? 4x4 for example. I still think these should be v4l. Kind of dependent on whether the output is 2d or 1d to my mind.
