The Axion 2 LRF XG35 runs a 640×480 core at 12 µm behind a 35 mm lens; the Talion XG35 runs 640×480 at 12 µm behind 35 mm. 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 1,750 m and 1,750 m. The Axion 2 LRF XG35 is lighter by 10.9 oz. Approximate prices are ~$3,000 and ~$2,400.

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.
