Autel EVO II Dual 640T V3 review
A weather-sealed (IP43) thermal drone with a longer 13 mm thermal lens, so warm targets fill more pixels from the same height. Best for: deer-recovery operators and hunters who fly in wet conditions and want more pixels on a target.
FCC-authorized before Autel joined the Covered List; sold new on Amazon by Autel’s official store.

Where the EVO II Dual 640T V3 is strong
- IP43 rating published by Autel: handles drizzle and dew-soaked nights
- 13 mm thermal lens gives a tighter view than the EVO Lite’s 9.1 mm
- Radiometric with 10 palettes and a 30 Hz thermal feed
What to watch for
- 38-minute flight time trails the Matrice 4T by 11 minutes
- No NETD or weight on Autel’s US pages
- Autel is on the FCC Covered List and the drone is not NDAA-compliant
Owner’s take: flying our own EVO II Dual 640T V3
The site owner bought and has flown an EVO II Dual 640T V3 for several months, after about a year flying DJI drones (notes received November 2026). Used for thermal imaging, inspection and general aerial work. No rain, wildlife or recorded flight-time tests.
Switching from DJI was easy. We expected a steep learning curve moving to Autel. Instead, the controller, menus and screen layouts felt familiar almost straight away, and most functions explain themselves. If you already fly DJI, you won’t be starting over.
Cameras. The 640×512 thermal camera performed very well and adds a whole extra dimension to finding things you can’t see by eye. We especially like the thermal overlay, which shows thermal and visual information together. The visual camera’s detail is excellent too. The temperature measurement options and Autel’s thermal analysis software are welcome extras, although we haven’t built a full reporting workflow around them yet.
Flight. It’s stable, holds position confidently, handles wind very well and is quieter than we expected. It coped well in the cold too (we didn’t time the batteries below freezing). Battery life has matched Autel’s figures in normal use, transmission range has been excellent, and obstacle avoidance and return-to-home worked well: it consistently landed within about two feet of its take-off point.
Support. After about five months our unit developed a fault. Autel responded quickly, handled the warranty claim efficiently and replaced the drone without hassle. That after-sales experience made a strong impression.
The downside is cost. It’s expensive, and Autel’s extended protection plans add a lot on top; we skipped extended coverage because of the price and sometimes wonder whether we should have.
Our verdict: yes, we’d buy it again. For search and rescue, inspection, public safety and other work that needs both thermal and visual imaging, it’s a capable high-end thermal drone without jumping to pricier enterprise platforms. It’s more than casual photographers need.
Autel EVO II Dual 640T Enterprise bundle V3
The 640T V3 comes as a standard model and an Enterprise version. The Enterprise V3 adds an accessory port for Autel’s spotlight, loudspeaker and strobe, plus an Enterprise-grade bundle; its thermal camera is the same 640×512, 13 mm, 30 Hz unit. Pick the Enterprise V3 if you’ll do search and rescue or public-safety work that needs those accessories; for hunting, recovery and inspection, the standard V3 is enough.
Who should buy it
Deer-recovery operators and hunters who fly in wet conditions and want more pixels on a target.

The palettes you’ll see on screen
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.
