Product overview
The Autel Robotics EVO Max 4NZ V2 is an aerial observation platform for public safety and emergency management, combining night-vision, wide-angle and infrared cameras with a laser rangefinder. Its MDX-1 aircraft weighs 1700 g with the ABX41-D intelligent battery, Fusion 4N V2 gimbal and propellers fitted. With arms extended and propellers included, it measures 563 × 657 × 147 mm around a 467 mm diagonal wheelbase. The XL814 camera assembly sits in a 250 g gimbal measuring 109 × 66 × 99 mm.
An expansion interface supports functional payload attachments, while an integrated night flight light and internal storage provide additional onboard facilities. Storage totals 128GB, with approximately 64GB available depending on firmware use. Battery hot swapping requires quick replacement to be enabled in Autel Enterprise. Operating temperature extends from -20°C to +50°C unloaded, narrowing to -20°C to +40°C fully loaded. Sensing capability depends on configuration: the downward 24G radar version lacks nighttime radar avoidance, while the six-direction 60G version supports it. Vision sensing requires textured surfaces and illumination above 15Lux; downward vision additionally requires diffuse surfaces with reflectivity above 20%.

| Vision obstacle sensing range |
|
| Vision and fused sensing field of view | Front/rear: horizontal 60°, vertical 80°. Left/right: horizontal 120°, vertical 90°. Up/down: 90° across the left-right axis and 120° across the front-rear axis. |
| Vision sensing environment | Front, rear, left, right and upward sensing require richly textured surfaces and illumination greater than 15Lux, such as normal indoor fluorescent lighting. Downward sensing also requires diffuse surfaces with reflectivity greater than 20%, such as walls, trees or people. |
| Radar transmission frequencies and night capability | 24G: 24.0–24.25GHz; 60G: 60–64GHz. The 24G downward-radar version supports visual obstacle avoidance only in good lighting and does not support nighttime radar obstacle avoidance. The six-direction 60G version supports nighttime radar obstacle avoidance.24G downward-radar and six-direction 60G radar aircraft configurations. |
| Radar obstacle sensing range | 60G: upward 0.3–18 m; downward 0.15–40 m; front/rear 0.5–18 m; left/right 0.5–18 m. 24G: downward 0.8–12 m.60G upward sensing references high-voltage wires; front/rear and side sensing reference high-voltage wires at 10 m/s flight speed. Downward ranges reference concrete ground. |
| Radar field of view | Horizontal: 60G ±25°, 24G ±15°. Vertical: 60G ±40°, 24G ±15°.Measured at 6dB. |
| Radar sensing environment | 60G supports six-direction obstacle avoidance by day and night and in all weather for objects including glass, water, wires, buildings and trees. 24G supports downward sensing: 12 m over concrete and no more than 6 m over grass thicker than 3 cm.60G avoidance distance varies with obstacle electromagnetic reflectivity and surface size; 24G downward range varies with ground material. |
| Fused radar and vision sensing | 24G configuration: front 0.5–30 m, rear 0.5–25 m, left/right 0.5–40 m, upward 0.5–40 m, downward 0.5–35 m. 60G configuration: front 0.5–30 m, rear 0.5–25 m, left/right 0.5–40 m, upward 0.3–40 m, downward 0.15–40 m. Front/rear/up/down sensing supports day/night and all-weather avoidance of obstacles including glass, water, small branches, buildings and high-voltage wires under the stated conditions.Front/rear/up/down sensing requires sufficient light or strong electromagnetic reflection from obstacles.
