Its Fusion 4N Pro payload combines a long-range night vision camera, a dedicated low-light night vision camera, a 640 × 512 thermal camera and a laser rangefinder in a single three-axis stabilized gimbal. This sensor combination gives law enforcement, security teams, emergency responders, search and rescue crews and other professional operators multiple ways to identify people, vehicles, heat sources and other targets after dark. The long-range night vision camera uses a 1/1.2-inch CMOS sensor with 8 MP effective pixels and ISO up to 800,000, while the low-light camera reaches ISO 440,000. The thermal camera supports temperature measurement from -20°C to 150°C and 0°C to 550°C, allowing operators to identify heat differences when conventional imagery is insufficient. With up to 50 minutes of flight time, 33 km maximum flight distance, IP43 protection and advanced obstacle sensing, the EVO III 4N Pro is built for demanding professional missions in both open and confined environments.

Ultra-Low-Light Vision and Thermal Target Detection

The Fusion 4N Pro is built around multiple imaging systems that allow operators to adapt to changing visibility instead of relying on a single camera.

• Long-Range Night Vision: The 1/1.2-inch CMOS camera provides 8 MP effective pixels, a 147 mm equivalent focal length and ISO from 100 to 800,000. Its 16× digital zoom helps operators examine distant subjects while maintaining a dedicated nighttime observation workflow.
• Ultra-Low-Light Wide View: The 1.69-inch CMOS low-light camera uses 2.3 MP effective pixels, a 43 mm equivalent focal length and ISO up to 440,000. With sensitivity down to 0.001 lux, it provides a wider view for locating and monitoring subjects in extremely dark environments.
• Radiometric Thermal Imaging: The uncooled VOx thermal sensor delivers 640 × 512 resolution and supports thermal super-resolution up to 1280 × 1024. Temperature measurement ranges from -20°C to 150°C in high gain mode and 0°C to 550°C in low gain mode.
• Laser Target Measurement: The integrated laser rangefinder measures distances from 5 to 2,000 m with an accuracy of ±(1 m + 0.15% of D). This allows operators to determine target distance and improve the accuracy of location information during field operations.
• Night Vision and Thermal Fusion: The 4N Pro combines ultra-low-light imaging with thermal information to provide a broader assessment of targets in darkness, unlit environments and visually complex scenes. Operators can use different sensor views to distinguish visual details from temperature differences.

AI Mission Automation and Multi-Drone Coordination

The EVO III platform combines onboard AI, advanced navigation and mesh networking to support coordinated enterprise operations.

• Automated Searches: Onboard AI supports automated search and patrol missions, allowing the aircraft to locate and track subjects while reducing repetitive pilot workload. The system can recognize and label more than 10 object classes, including people, vehicles, boats, drones and flames.
• Dynamic Object Tracking: EVO III can continuously track moving objects and automatically adjust its flight position and viewing angle to keep the subject in the optimal observation area. If the subject briefly leaves the field of view, the system can automatically reacquire it.
• Eight-Node Mesh Network: The EVO III mesh system supports up to 8 nodes using combinations of aircraft and remote controllers. Teams can share video feeds, mission information, drone locations, points of interest, target coordinates and telemetry data.
• Mission Handoff: Multiple aircraft can work around the same target or area and transfer an ongoing mission when another drone needs to take over. This can help maintain coverage when an aircraft needs to return because of low battery.
• Offline Networking: The mesh network can operate without cellular service, internet access or external servers. This provides an additional communication option for remote locations and environments where conventional connectivity is unavailable.

Long Endurance, Rugged Construction and Advanced Flight Safety

The EVO III 4N Pro combines extended endurance with sensing and navigation features designed for demanding field environments.

Maximum flight distance is rated at 33 km, with actual performance depending on payload, wind, temperature, altitude and operating conditions.
• 23 m/s Flight Speed: Performance Mode provides a maximum horizontal speed of 23 m/s forward, 18 m/s backward and 20 m/s sideways. Maximum wind resistance during horizontal flight is 12 m/s.
• IP43 Protection: The aircraft carries an IP43 protection rating and is designed to operate from -20°C to 50°C. This gives professional teams greater flexibility when working in changing outdoor conditions.
• Omnidirectional Sensing: The aircraft combines visual sensing, forward millimeter-wave radar and a downward ToF sensor. Forward sensing can detect obstacles from 0.5 to 40 m in supported conditions, while the system supports effective obstacle avoidance at speeds up to 25 m/s.
• GNSS-Denied Navigation: Vision-based positioning and high-precision SLAM navigation allow EVO III to maintain stable positioning in environments where GNSS signals are weak or unavailable. This supports indoor operations, nighttime missions and other challenging environments.

Professional Control, Connectivity and Enterprise Workflow

The EVO III 4N Pro is designed to work as part of a wider professional operating system rather than as an isolated aircraft.

• Smart Controller V3: The compatible controller features a 7.9-inch touchscreen with 2048 × 1536 resolution and up to 2,000 nits brightness. It provides 128 GB onboard storage, HDMI output, USB-A and USB-C ports, and up to 4 hours of battery life at 50% screen brightness.
• Long-Range Transmission: The EVO III supports maximum transmission distances of 25 km under FCC conditions and 15 km under CE and SRRC conditions in open environments without interference. Actual range varies according to local regulations and operating conditions.
• 4G-Enhanced Transmission: The EVO III platform supports an optional 4G-enhanced video transmission module with high-gain onboard antennas. This can improve connectivity in challenging environments such as dense urban areas and locations between buildings.
