Autel EVO Lite 640T Enterprise review
The cheapest new drone with a full 640×512 radiometric thermal camera, and the lightest one in this list at 866 g. Best for: hunters, landowners and first-time roof inspectors who need real thermal at the lowest new price.
FCC-authorized before Autel joined the Covered List; sold new on Amazon by Autel’s own store.

Where the EVO Lite 640T is strong
- Lowest price band of any real 640×512 thermal drone on Amazon
- Radiometric, with a published measurement range and ±3 °C accuracy
- Folds small and weighs well under a kilogram, so it packs into a hunting bag
What to watch for
- Autel publishes no NETD, frame rate or IP rating for it
- Single 9.1 mm thermal lens: a wide view, so targets look smaller at height
- Autel is on the FCC Covered List and the drone is not NDAA-compliant
Autel Robotics EVO Lite Enterprise gimbal
The EVO Lite Enterprise uses a three-axis gimbal carrying both cameras: the 640×512 thermal camera (9.1 mm lens) and the 48 MP visual camera. That lets you split-screen thermal and visual and tilt straight down for grid searches and roof surveys. The EVO Lite 6K Enterprise uses the same airframe with a 6K visual camera and no thermal, so check the model name before you buy.
Autel EVO Lite 640T Enterprise 7.9 premium package
Autel sells the 640T in several bundles. The premium package pairs the drone with Autel’s 7.9-inch Smart Controller, a brighter, larger screen that’s easier to read at dawn and dusk, plus extra batteries and a hard case. The Basic Combo is the cheapest way in; the bigger screen is worth it if you’ll spot small heat signatures for long sessions. Compare what’s in the case on each listing: bundle contents change more often than the drone.

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.
