Pros & Cons

FLIR TG165-X Thermal Imaging Camera

Pros

  • Trusted FLIR name and rugged inspection-tool positioning
  • Good fit for trades-adjacent buyers who want a dedicated tool
  • Simpler than app-based modules when you need quick spot checks

Cons

  • Native thermal resolution is low for the price
  • Lower refresh than many budget 25 Hz imagers
  • Buyers paying for the FLIR ecosystem should know the pixel tradeoff

TOPDON TC004 3.5-inch Thermal Imaging Camera

Pros

  • Higher claimed imaging output than the smallest standalone cameras
  • PC analysis, video, and large storage make it more credible for repeated inspections
  • Standalone display is easier to work with than phone modules in tight spaces

Cons

  • Premium price means the TC004 Mini may be enough for many buyers
  • Still uses super-resolution language that needs careful comparison
  • Larger tool to carry than USB-C modules

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.
