Caterpillar offers phone with built-in FLIR camera
The lack of a replacable battery is infuriating because it's planned obselescence of a FLIR device. I got one of the first CAT s60 phones when they came out and tolerated all the android spyware on it because I really liked having a properly ruggedized phone. Got about 4 years out of it.<p>The flir camera I would say I used most often at night for finding my dogs poop to pick up on neighbours lawns in the dark, but I used it on boats to find moisture,  motorcycle engine seals to find gasket problems,  found contractor fraud where they didn't bother putting insulation behind drywall, and places around windows for caulking to reduce heat loss, heat on horses legs that indicated inflammation, lack of current on wires in my basement. Mostly novelty, but handy.<p>The battery became too flaky to use as a regular phone, so I keep it in my toolbox and use it as a stud finder behind drywall and used to find where animals were getting into the attic of the house. Next test is for rim leaks on car tires. It has been a small time saver, and a fun conversation piece. But yeah, military thermal imaging to find dog poop at night was most common use case.
