A Comprehensive Feature-by-Feature Comparison for Enterprise Operations

By DJI Enterprise DJI Enterprise
June 18, 2025

The DJI Matrice 400 (M400) delivers a comprehensive upgrade over the Matrice 350 RTK, offering improvements in flight performance, payload capacity, sensing technologies, transmission, intelligence, automation, and accessories. 

1. Longer Flight Time

The M400 offers a maximum flight time of 59 minutes when equipped with a single H30T, L2, or P1 payload—nearly 50% longer effective flight time than the M350 RTK under similar conditions. This upgrade significantly enhances mission efficiency for long-duration tasks such as emergency response, large-area mapping, and corridor inspections.

3. Faster and More Efficient

The M400 offers superior speed across all metrics. It achieves a flight speed of 25 m/s and route speed of 25 m/s—60% higher than the M350 RTK. It also supports higher ascent (10 m/s) and descent (8 m/s) speeds.

Max Speed 23 m/s 25 m/s
Route Speed 15 m/s   25 m/s
Ascent Speed   6 m/s 10 m/s
Descent Speed 5 m/s 8 m/s

4. Enhanced Safety and Reliability

The Matrice 400 significantly enhances obstacle avoidance through a fusion of rotating LiDAR, six-direction mmWave radar, and four full-color low-light fisheye vision sensors:

- Rotating LiDAR: Delivers high-precision 3D depth information, enabling accurate environmental modeling even in extreme lighting conditions, including strong sunlight or darkness.

- mmWave Radar: Provides strong penetration in rain, fog, and snow, capturing both range and velocity information in real-time.

- Vision Sensors: The four full-color low-light fisheye cameras capture rich visual features such as color, shape, and texture, enabling full-color flight assist displays.

Thanks to this comprehensive sensing suite, the M400 can detect fine obstacles such as overhead power lines, even when flying at night across mountainous terrain. Its all-weather system provides enhanced operational safety in rain and fog.

At 25 m/s, the M400 can detect and bypass primary grid lines (21.6 mm steel-core aluminum conductors). At 17 m/s, it can detect and avoid both primary and secondary distribution lines (12 mm). This level of obstacle avoidance is a breakthrough for UAV missions in power inspection and high-risk environments.

5. Enhanced Video Transmission

The Matrice 400 is equipped with the new DJI O4 Enterprise transmission system, which offers up to 40 km of range under FCC conditions—double that of the M350’s O3 Enterprise system. It also supports dual 4G dongles for network redundancy and airborne relay for signal extension across obstructed environments.

In addition to the standard 2.4/5.8 GHz bands, the M400 introduces support for a sub-2G transmission band, which enhances signal stability in interference-prone or long-distance scenarios. This sub-2G frequency varies by region—1.4 GHz is used in China, while 900 MHz is deployed in countries such as the United States, Canada, Australia, Japan, Brazil, Taiwan (China), Singapore, and Malaysia. Operators should ensure compatibility with local frequency regulations prior to deployment.

With support for both visible light and thermal imaging, the Matrice 400 offers enhanced detection capabilities when paired with the Zenmuse H30 series. It can intelligently identify targets such as vehicles and vessels, switch between different detection models, and automatically count objects within its field of view.

7. Advanced Automation

The Matrice 400 supports enhanced mission execution features such as real-time obstacle bypass during L2-guided routes, and flight path planning for slopes, geometric structures, and building facades. These capabilities are managed through DJI Pilot 2 or FlightHub 2, greatly streamlining complex operational workflows without requiring constant manual control. In comparison, the M350 RTK supports only basic flight path execution.

8. AR Features for Awareness

The M400 introduces rich AR overlays on the controller screen—visualizing powerlines, route paths, map data, and landing points. Operators gain more spatial awareness and planning clarity, reducing risks during complex operations.

AR Powerline Warning

This feature automatically detects overhead power lines in front of the drone and overlays clearly visible AR lines on the remote controller screen. Even in low-light or complex environments such as mountainous terrain or densely built areas, operators gain an intuitive visual reference to avoid wire collisions, improving operational safety—especially during inspection tasks.
 

AR Map Labels

The remote controller can display real-time labels for landmarks, buildings, and roads on the map interface. Users can toggle display categories based on mission needs, making urban operations more intuitive and helping pilots maintain orientation during complex navigation scenarios. 
 

AR Return Path

While executing Return-to-Home (RTH), obstacle bypass, or FlyTo commands, the drone’s planned path is displayed as an AR line overlay. This allows operators to visually monitor the exact flight path in real time, ensuring better situational awareness and reducing the risk of routing errors.

AR Landing Point Visualization

As the drone descends, an AR shadow of the aircraft is projected onto the landing area on-screen. This helps the operator verify whether the current landing location is clear and safe, reducing the risk of hard landings or ground collisions in constrained environments.

AR Drawing and Measurement

Without requiring 3D modeling, users can mark points directly on the controller screen to acquire geographic positions, draw lines to measure distances, and define areas to calculate surface size.
 
Measurement results can be synced to DJI FlightHub 2 to support collaborative mission planning and team coordination in real time.

  • Real-Time Terrain Following
    This feature enables the aircraft to maintain a constant relative altitude to the ground while flying manually or along pre-defined flight routes.
    It is especially useful in mountainous regions or during low-altitude mapping, ensuring consistent ground sampling distance (GSD) and reducing the need for constant zoom or manual altitude adjustments.


  • Ship-Based Takeoff and Landing
    M400 can take off from stationary or slow-moving vessels and accurately land by recognizing deck patterns.
    This capability significantly expands operational scope to offshore environments such as maritime patrol, wind farm inspection, or rescue missions at sea.

  • Cruise Mode
    With Cruise Mode, the pilot can set the drone to fly continuously in a given direction at a constant speed—without needing to press the control sticks. 
    This mode is ideal for long-distance linear inspections (like pipelines or roads), reducing pilot fatigue and improving path consistency.



  • FlyTo Target
    In emergency or dynamic scenarios, this feature allows the drone to automatically calculate the optimal flight path and speed to reach a designated target.
    It adapts to real-time environmental inputs (e.g., obstacles, terrain) to ensure a safe and efficient approach.


  • POI (Point of Interest) Orbiting
    POI mode enables the aircraft to circle around a designated object or area while keeping the camera focused on it. This function is particularly valuable for structural observation, 3D modeling, and video capture, as it allows stable and smooth perimeter coverage without complex manual control.

     

  • Observed View
    The system can display previously observed ground areas and the camera center's current location directly on the remote controller map.
    This real-time feedback allows operators to avoid redundant coverage and ensure all intended targets or zones are inspected or captured.
