What the thermal camera sees from above
Calculated for a camera pointed straight down; each animal is drawn at its true length in sensor pixels (the cow from above, the deer and hog at a camera angle). One square is one sensor pixel, on one scale throughout.

Shape means about 12 pixels nose to tail and 3 across the back. Pilots usually find animals on thermal from 200 to 400 feet and confirm with the zoom camera. FAA rules cap most flights at 400 feet above the ground. Trees, a tilted camera and sun-warmed ground all cut these figures; upsampled "super resolution" modes and digital zoom add no detail.
Specs
| Sensor | |
|---|---|
| Resolution Sensor resolution How many heat-reading pixels the sensor has, such as 384 × 288 or 640 × 512. More pixels show more detail, but the lens matters just as much. | 640 × 512 |
| Pixel pitch Pixel pitch The size of each sensor pixel, in microns. Smaller pixels mean more magnification from the same lens. Most current thermals use 12 microns. | 12 µm |
| NETD (maker’s claim) NETD (thermal sensitivity) How small a temperature difference the sensor can show. Lower is better, but brands measure it differently, so numbers from two makers are not a fair comparison. | — |
| Refresh rate Refresh rate How many times per second the picture updates. 50 or 60 times a second looks smooth; lower rates stutter when you pan or a coyote runs. | 25 Hz |
| Optics | |
| Lens Focal length The lens number in millimeters, like 35 mm or 50 mm. A longer lens puts more pixels on a distant animal but shows a narrower slice of ground. | 13 mm |
| Base magnification Base magnification How much bigger things look before any digital zoom, like 2× or 4×. Higher is not automatically better: it narrows your view. | 1× |
| Max digital zoom Digital zoom Electronic enlarging of the picture. It makes the animal look bigger but adds no detail; past about 2× to 4× the image gets blocky. | 16× |
| Field of view Field of view How wide a view you get, in degrees. A wide view makes scanning for animals faster; a narrow one usually means more magnification. | 33° × 26° |
| Detection range (maker’s claim) Detection range The maker's figure for how far away a warm object shows up as a dot or two. It is far longer than the distance you can tell what the animal is. | — |
| Display | |
| Display Display resolution How many pixels the small screen inside the eyepiece has. A sharp screen looks cleaner but cannot add detail the sensor did not capture. | Not published |
| Power | |
| Battery | Autel Smart Battery XE3_7100_1155 (7100 mAh), removable |
| Features | |
| Rangefinder Laser rangefinder A built-in laser that measures how far away the animal is. The rated range is for big, reflective targets; expect much less on a coyote. | No |
| Storage Onboard recording (storage) Built-in memory that records photos and video of what you see. Useful for reviewing shots and sharing hunts; listed in gigabytes. | 8 GB |
| Wi-Fi / app Wi-Fi and app A wireless link to a phone app for live viewing, downloading videos, changing settings and updating the device's software. | — |
| Drone | |
| Thermal camera | Built in |
| Visual cameras | 50 MP wide (1/1.28-inch) and 12 MP wide (1/2-inch), 16x digital zoom |
| Radiometric | Yes |
| Flight time | 38 min (no wind) |
| Wind resistance | 24 mph |
| Range (FCC) | 6.2 mi |
| Takeoff weight | 2.7 lb (FAA registration required) |
| Spotlight / speaker | — / — |
| Build | |
| Weight Weight How heavy the device is. Check whether the maker weighed it with or without the battery, because brands do it differently. | 42.6 oz |
| Water rating IP rating (water rating) A two-part code for how well the device keeps out dust and water. IP67 means dust-tight and survives a short dunk; an X means not tested. | Not rated |
| Operating temp Operating temperature The temperature range the maker says the device will work in. Batteries lose much of their runtime well before the low end of that range. | 14°F to 104°F |
| Buying | |
| Warranty Warranty How long the maker promises to repair or replace a faulty unit. Check whether it needs registration and whether it passes to a second owner. | Not published for US |
| US price US price The price we found for the unit in the US, with where it came from and when. Prices change often, so treat it as a snapshot. | $4,799 |
| MSRP MSRP The maker's suggested retail price in the US: the list price, before any sale. Useful for seeing how good a deal really is. | Not published for US |
