Our Verdicts
FLIR TG165-X Thermal Imaging Camera
The FLIR TG165-X is the conservative tool pick, not the pixel-value pick. It makes sense when ruggedness and FLIR familiarity matter more than maximum resolution per dollar.
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.
