Make sure you take RAW-pictures (+JPEG) when taking photos. In my first few months with a new camera I only shot JPEG-pictures, now I regret it.
RAW-files from your camera can be processed with Darktable in every direction you like. But you need to watch a lot of video tutorials and read the manual / other ressources to get good results.
It feels great, as soon as you get used to it.
That is also depending on your budget.
The Bosch infrared camera fits your needs, but the price is high. It has 'normal' Bosch battery packs, rechargable and swappable.
Pictures have a good quality (still small, it's an infrared camera after all). But the calibration time is quite long and happens often, especially when the outside temperature changes a lot (going inside/outside). Annoying, but probably necessary.
