The Autel EVO Lite 640T Enterprise, also searched as EVO Lite 640T, Autel EVO Lite 640T thermal drone, and Autel thermal drone, is a compact enterprise UAV built for teams that need fast deployment, radiometric thermal imaging, and reliable situational awareness in a lightweight platform. It is positioned for public safety, emergency response, inspection, patrol, and other missions where portability matters as much as sensor capability.
For buyers researching a thermal drone for inspection, search and rescue thermal drone, or compact enterprise thermal drone, the value proposition is straightforward: the EVO Lite 640T Enterprise combines a 640×512 radiometric thermal camera, a 48MP visible-light camera, AI target recognition, and 40-minute flight endurance in a foldable airframe that weighs just 866 g. That combination makes it well suited for single-operator deployment when speed, mobility, and actionable thermal data are the priority.
The core of the EVO Lite 640T Enterprise is its dual-gimbal payload, pairing a visible-light camera with a thermal imager so operators can quickly move from broad scene awareness to precise heat-source detection. Unlike a consumer camera drone, this platform is designed around operational decision-making, not just image capture.
Thermal Imaging Camera: The aircraft uses an uncooled VOx microbolometer with 640×512 thermal resolution, 9.1 mm focal length, f/1.0 aperture, 12 μm pixel pitch, 8–14 μm wavelength, and up to 16× digital zoom. Autel lists thermal sensitivity at ≤50 mK, which helps the system reveal subtle temperature differences during inspection, search operations, and heat-source localization.
Visible-Light Camera: For visual documentation and navigation, the EVO Lite 640T Enterprise includes a 1/2-inch CMOS wide camera with 48MP stills, 24 mm equivalent focal length, f/2.8 aperture, and up to 4K/30p video. This gives teams the visual context they need to confirm a target, document findings, and maintain situational awareness during daylight or mixed-light missions.
The EVO Lite 640T Enterprise is more than a drone with a thermal feed. It is a radiometric thermal platform, meaning the thermal camera captures temperature data that can be measured and analyzed during flight. Autel lists multiple radiometric measurement methods, temperature alert thresholds, and area-based temperature reporting with coordinates, which helps crews move from spotting heat to evaluating it.
The thermal system supports -20°C to 150°C in high-gain mode and 0°C to 550°C in low-gain mode, with stated measurement accuracy of ±3°C or ±3% of reading, whichever is greater. It also supports multiple thermal palettes, including White Hot, Black Hot, Rainbow, Ironbow, and other display options that help isolate anomalies in different operating environments.
For teams that need evidence and post-mission review, the drone records radiometric JPG thermal images and 640×512 thermal video at 30 fps, making it useful for maintenance reports, incident documentation, and recurring inspection workflows.
Autel built the EVO Lite 640T Enterprise around AI target recognition and positioning. Using the visible or thermal view together with onboard AI, the system can automatically recognize and locate people, vehicles, and boats, then project those positions onto the map. For public safety, patrol, and search work, that is a meaningful operational advantage over a basic thermal camera feed alone.
The aircraft also supports offline maps, which is useful in weak-signal or no-network environments, and it uses GPS/BDS/GLONASS for positioning. Autel lists hover accuracy of about ±0.3 m with GNSS and tighter accuracy when visual positioning is active. The platform also includes three-way binocular vision obstacle avoidance, with forward, rear, and downward sensing to improve flight safety in real-world field conditions.
A major reason buyers consider the EVO Lite 640T Enterprise is that it delivers enterprise thermal capability in a small package. The aircraft weighs 866 g, folds down to 210 × 123 × 95 mm, and is built for single-operator deployment. That makes it easier to store in a vehicle, carry into the field, and launch quickly during urgent missions.
Autel rates the platform for up to 40 minutes of flight time, 37 minutes of hover time, and 12 km maximum transmission distance in FCC regions. It also includes 4 GB internal storage with microSD support up to 256 GB. In practice, that means longer on-station time and fewer interruptions during inspections, patrol sweeps, and thermal search tasks.
In practical terms, the Autel EVO Lite 640T Enterprise is best understood as a portable thermal response drone. It is optimized for users who want radiometric thermal capability, visible-light confirmation, AI scene awareness, and quick deployment without stepping up to a larger and heavier enterprise airframe. Its strongest fit is for inspection, patrol, emergency response, and public-safety workflows where mobility and speed matter.
