If you're looking for a low cost thermal camera with industrial grade, macro lens,and build in battery, I'd like to recommend the InfiRay T2S Plus. It's capable of incredible 8mm macro, no other camera on the market especialy at this price can do that.
The InfiRay T2S Plus thermographic camera comes with a built-in 9mm macro lens that allows you to get up real close to the subjects like the mother board and have it be in focus and be able to clearly see the surface of the board. And the thermal imager has a 256*192 resolution and 25 hertz fast refresh rate that means as you're moving the board around under the thermal camera is a lot smoother motion versus the Seek thermal camera, which is around 9 hertz. And that basically means 25 times per second. And that's about a macro lens which is adjustable so you could twist the ring to get better focus.
