The Jockey 640 runs a 640×480 core at 12 µm behind a 25 mm lens; the Sidekick 640 runs 640×480 at 12 µm behind 19 mm. On the Johnson yardstick they detect a person at 521 m and 396 m and recognize one at 130 m and 99 m; the boxes say 932 m and 709 m. The Sidekick 640 is lighter by 5.0 oz. Approximate prices are ~$3,799 and ~$3,299.

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.
