Our Verdicts
TOPDON TC002C Duo USB-C Thermal Camera
The TC002C Duo is the phone-module upgrade pick. It is for buyers who want more thermal detail than an 80 x 60 module while keeping the camera small enough to live in a tool bag.
TOPDON TC004 Mini Thermal Imaging Camera
The TOPDON TC004 Mini is the best first-camera starting point because it gives practical standalone scanning, a useful temperature range, and a sane mid-range price without forcing buyers into a phone app.
