The range on the box, and the range the sensor and lens can actually deliver.
Every unit here gets three ranges computed from two published numbers — pixel pitch and focal length — using the same Johnson criteria the military specs thermal against. Detect, recognize, identify. Then the manufacturer’s figure is printed beside them, so you can see which yardstick each one uses. Across the 60 units that publish a claim, the box averages 2.3× our detection estimate.
