This iPhone thermal camera accessory is one of my favorite tools, and it's $60 off for Amazon Prime Day

The industrial-grade Topdon TC002 gives your iPhone a cool superpower and you can get it for much less than a dedicated thermal imaging camera, thanks to this Amazon Prime Day deal.

Adrian Kingsley-Hughes/ZDNET I have quite a few Android smartphones that have built-in thermal cameras (such as the Blackview BV8900 or the Ulefone Power Armor 18T), and I find them really useful.
