The ThOR 5 LRF 640 2-16x runs a 640×480 core at 12 µm behind a 25 mm lens; the RICO Micro V2 RH25 runs 640×480 at 12 µm behind 25 mm. On the Johnson yardstick they detect a person at 521 m and 521 m and recognize one at 130 m and 130 m; the boxes say 2,470 m and 1,260 m. The RICO Micro V2 RH25 is lighter by 22.9 oz. Approximate prices are ~$2,995 and ~$3,999.

Estimated from pixel pitch and lens focal length using the Johnson criteria (2, 8 and 13 pixels across a 0.5 m human critical dimension), clear air, 50 % probability. A model of the optics, not a measurement — real range depends on temperature contrast, humidity and the animal.
