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 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.
