Thermal imaging cameras are fundamentally low-resolution. The thermal core they use can't pick up a tiny fraction of the number of pixels you get on even a cheap conventional camera sensor, and even models with QVGA (320-by-240) resolution can cost thousands of dollars and are limited to specific professional applications. That's why Flir, one of the leading companies in thermal imaging, has stuck to an 80-by-60 resolution for its consumer-level Flir One camera phone accessories for years. That's also what makes the $399.99 Flir One Pro stand out. It has a thermal resolution of 160 by 120, quadrupling the number of pixels it can capture. Combined with the ability to measure higher temperatures than the third-generation Flir One or the Flir One Pro LT, the Flir One Pro is by far the most powerful model yet, and our Editors' Choice. Design The Flir One Pro looks more rugged than the slightly rounded, metallic silver-pink Flir One, with a slightly chunky black body and sharper angle...
The Flir One Pro is the most powerful consumer-level thermal camera accessory available, with remarkably high resolution and temperature measurement.
High resolution for a thermal camera; Lots of powerful metering and adjustment options
High temperature mode not particularly useful outside of very limited situations
