Resolution and image quality
One Topdon listing states 256×192 native capture enhanced to 512×384 with TISR technology, and the other adds 40mK sensitivity with a 25Hz refresh rate. The FLIR listings state lower native figures, 160×120 on the Pro and 80×60 on the standard One, upscaled by VividIR to 480×360 and 240×180. Both sides blend a visual image with the thermal image: Topdon lists image fusion with the phone camera, while FLIR lists MSX merging thermal and visual images in real time. On stated resolution alone, the Topdon side leads; on blending, each side names its own method, so the listings leave no shared figure to rank them by.
Temperature range and accuracy
The Topdon listings state a -4°F to 1022°F range (-20°C to 550°C). One listing adds readings accurate within 3.6°F (2°C) or 2% and to 0.1°C, plus continuous measurement with a waveform graph of high, low and average temperatures, while the other states ±2% accuracy. The FLIR listings state no full range; they state accuracy of ±3°C or ±5% when the unit is within 15°C to 35°C and the scene is within 5°C to 120°C. The two sides state accuracy in different units and under different conditions, so do not call one side more accurate on these figures alone.
App features and power
The FLIR listings put step-by-step inspection guides in the Flir One app for typical faults, air leaks and moisture buildup, and one Topdon listing puts point, line and surface detection with 9 color palettes in the TC001 app. The Topdon camera has no internal battery and draws 0.35W from the phone, with 4-7 hours stated for phones from 3000-5000mAh; the FLIR listings state no battery figure and describe a camera that plugs directly into the phone charging port. One Topdon listing includes a 19.7 in cable with a USB converter, an EVA bag and a wiping cloth, and the other a 19.7 in extension cord, an EVA bag, a quick guide and a cleaning cloth; the FLIR listings include a case and a USB cable.
Durability and warranty
The FLIR listings state a 1.5 meter drop rating and describe the cameras as jobsite tough, while the Topdon listings state no drop rating. Warranty terms also differ: one Topdon listing states 1 year and the other states no term, the FLIR One Pro listing states 2 years parts and labor on the camera with 10 years coverage on the detector, and the standard FLIR One listing states 1 Year. If warranty length and drop protection matter to the job, the FLIR Pro listing states the strongest terms here.
