The best way is probably to use the raw camera output.
The other way would be to remove the UI elements (battery indicator etc), extract the temperature scale (both the numbers and the colormap to convert the colors to temperatures). Then you can use rgb2ind and index into the lookup table you have created from the scale to get the temperature image. See why I would suggest using the raw output of your camera?
Only when you have better data can you start with this task. What do you mean by hotspot? What is a spot? Can there be multiple? Is a large area multiple semi-overlapping spots, or a single big spot? What is hot?
Most of these questions will depend on what you want to do next.

Do you have the thermal data? I think the cheapest FLIR One camera only gives you a pseudocolored image but if youi pay like $100 more you can get the version that gives you the image in units of degrees instead of RGB. That is what you need. Otherwise you're stuck doing something like in the attached demo, which is not ideal.
