> Most camera sensors already detect in the IR range, you just need to remove the filter. I've done it, works great and pretty fun

It's not the same IR you'd need for military purposes, you're seeing a tiny percentage of the IR spectrum, and it's the most useless. That's why any semi decent military tier system costs 50k+ a pop. Civilian tier scopes are 1k+ and pretty shit, you won't see anything smaller than a human more than 1km away.
