The LUMI L35R runs a 384×288 core at 12 µm behind a 35 mm lens; the QUEST H35R runs 640×512 at 12 µm behind 35 mm. The QUEST H35R has 3.0× the pixels. On the Johnson yardstick they detect a person at 729 m and 729 m and recognize one at 182 m and 182 m; the boxes say 1,600 m and 1,800 m. The LUMI L35R is lighter by 11.1 oz. Approximate prices are ~$2,200 and ~$3,650.

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.
