Autel EVO Max 4T — Product Description
The New Flagship for Industrial Drone Applications
The EVO Max 4T is Autel’s most advanced enterprise drone, powered by an industry-leading 8-core processor delivering 26 TOPS of AI compute. Designed for security, inspection, and surveying professionals, it combines autonomous flight intelligence, all-weather obstacle avoidance, and a quad-sensor imaging payload in a single compact platform.
Key Highlights
720° Omnidirectional Obstacle Avoidance — All-Weather Operation The EVO Max 4T fuses binocular fisheye vision with millimeter-wave radar for full-sphere perception and obstacle avoidance. It operates safely under bridges, near high-voltage power lines, and in other complex environments — day or night, without interruption.
GPS-Free Precision Navigation In environments where GPS is unavailable, jammed, or spoofed, the EVO Max 4T still delivers high-accuracy, low-latency positioning for reliable indoor and outdoor navigation.
Autonomous Flight Planning Powered by Autel Autonomy technology, the drone performs real-time 3D scene reconstruction, global path planning, autonomous obstacle circumnavigation, and return-to-home — across mountains, forests, and urban environments.
Triple Anti-Interference Technology Built-in flight controller, GPS receiver, and video transmission modules provide outstanding resistance to electromagnetic interference, RF jamming, and GPS spoofing for maximum flight stability.
Outstanding Performance 42-minute flight time · IP43 weather protection · 12 m/s wind resistance · 7,000 m max takeoff altitude · 20 km video transmission range. Internal supercapacitor enables hot-swappable batteries for seamless continuous operations.
Industry-First A-Mesh Aerial Networking Proprietary A-Mesh technology enables drone-to-drone and drone-to-ground multi-device networking — supporting one-controller-multi-drone and master/slave dual-control modes. Communication range extends to 50–100 km via relay nodes, without requiring existing network infrastructure.
