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 3.5-inch Thermal Imaging Camera
The TOPDON TC004 3.5-inch model is the sensible TOPDON upgrade when you want more storage, PC analysis, video, and a larger standalone workflow.
