Thermal drones, read straight from the spec sheet
A thermal drone is a drone carrying an infrared camera that sees heat instead of light, so it can find a person, an animal or a failing roof seal in total darkness. Real ones carry a 640×512 sensor and start a little over $3,000 new.
This site compares every thermal drone you can still buy in the US, using only manufacturer spec sheets, and says plainly where a spec isn’t published.

Thermal drones in the US right now
Two changes reshaped the market in the last year. On December 22, 2025, the FCC added DJI and Autel Robotics to its Covered List. Drones those companies had already authorized, including the DJI Matrice 4T and Autel’s 640T models, can still be sold and flown; new models can’t be authorized. The FCC has also proposed barring imports of foreign drones with thermal imaging. That rule is not final, but it is why every product on this site carries an availability tag.
The second change: DJI’s compact Mavic 3 Thermal is discontinued, and the Matrice 4T replaced it. Several ranking guides still list the Mavic as a current pick. Ours doesn’t. Read the thermal drone rules explained for what this means if you fly commercially.
Thermographic camera drones: when the drone measures temperature
A thermographic camera drone doesn’t just show heat; it records a temperature value for every pixel. The industry word is radiometric. Roofers, solar technicians and insurance adjusters need it, because a report has to say “this cell is 18 °C hotter than its neighbours”, not just “this spot looks bright”. Every 640×512 drone in our ranking is radiometric; DJI publishes the tightest accuracy (±2 °C or ±2 % on the Matrice 4T). See the thermal inspection drone picks.
UAV thermal imaging cameras: what’s inside one
Almost every UAV thermal imaging camera is built around an uncooled microbolometer: a grid of tiny vanadium-oxide (VOx) sensors that change resistance as long-wave infrared hits them. Three numbers describe it: resolution (how many pixels), NETD (the smallest temperature step it can separate from noise, in millikelvin) and frame rate. Teledyne FLIR supplies the Boson cores inside the Skydio X10 and Parrot ANAFI USA; DJI and Autel use their own modules. How thermal drones work goes deeper.
IR camera UAVs and drones with infrared cameras
“IR camera UAV” and “UAV with infrared camera” usually mean thermal, but not always. Infrared covers a wide band. Thermal cameras read long-wave infrared (roughly 8–14 µm), which objects give off as heat. Near-infrared is reflected light, the kind security cameras use with an IR lamp. A drone listing that says “infrared” may mean an IR obstacle sensor or an NIR lamp, not a thermal camera. Look for a stated thermal resolution such as 640×512. If there isn’t one, it isn’t a thermal drone.
What separates a good thermal imaging drone from a toy
Sensor first. A 640×512 sensor puts four times as many pixels on a target as a 320×256 one, which is the difference between “warm blob” and “deer, lying down”. After that: sensitivity (NETD), a second visual camera with zoom to confirm what you found, flight time, and a weather rating if you fly in dew or drizzle. The thermal drone buying guide explains each in turn, and the spec comparison table lines them up.
Thermal sensor resolution, drawn to scale
Same scene width, same warm figure. Each square is one thermal pixel (grid lines hidden at 1280 so it stays legible). More pixels on a target means you can tell a deer from a hog, or a person from a rock, from higher up.
Grids are drawn at one-tenth scale: 32 columns stand for 320, and so on.
NETD (noise-equivalent temperature difference) is the smallest temperature step the sensor can separate from its own noise, in millikelvin (mK). 30 mK beats 50 mK. How thermal sensors work.
Thermal palettes, side by side
A palette only changes how temperatures are coloured; it never adds detail. Names vary by maker: DJI calls Iron “Iron Red” and “Hot Iron”.
- White HotDefault for spotting people and animals: warm targets glow white against a dark scene.
- Black HotEasier on the eyes for long night searches; many SAR pilots prefer it.
- IronInspection reports: small temperature steps on roofs and panels read clearly.
- RainbowHighest contrast between close temperatures, such as moisture under a membrane roof.
- LavaSeparates the hottest objects while keeping cool background detail.
- ArcticHighlights hot spots in gold over a blue scene: electrical and solar faults.
Short answers
Is a $500 thermal drone real?
No. We found no new drone under $2,000 with a thermal sensor its manufacturer actually specifies. Real 640×512 thermal drones start in the $3,000–$8,000 band (the Autel EVO Lite 640T Enterprise is the cheapest), and quote-only US-made models sit above $8,000. Full tier breakdown: how much is a thermal drone.
Can you still buy a DJI thermal drone new in the US?
Yes, for now. The Matrice 4T was authorized before DJI was added to the FCC Covered List on December 22, 2025, so it is still sold new. New DJI models can’t be authorized, and the Mavic 3 Thermal is discontinued. Details on the DJI thermal drone page.
What can a thermal camera not see?
Anything behind a barrier. A thermal camera reads the heat coming off surfaces; walls, glass and water block long-wave infrared, and a full leaf canopy hides what’s under it. A thermal drone sees the outside of a building, not inside it. More on thermal drones and privacy law.
