DJI O4 Air Unit Pro

DJI O4 Air Unit Pro – Flagship 4K Digital FPV Transmission System

The DJI O4 Air Unit Pro represents the next evolution of digital FPV transmission and onboard recording performance. Built for professional pilots and competitive racers, this system combines ultra-low latency video transmission with cinematic 4K recording capability inside a compact 32-gram design.

At the heart of the system is a powerful 1/1.3-inch CMOS sensor capable of capturing 4K video at up to 120 frames per second. This larger sensor improves dynamic range, color depth, and low-light performance, allowing pilots to capture high-definition footage without mounting an external action camera. The 155° ultra-wide field of view delivers immersive flight visuals while maintaining clarity at high speeds.

O4 Air Unit Pro Digital Transmission Performance

The DJI O4 Air Unit Pro uses DJI’s latest digital video transmission architecture to deliver responsive control and smooth live view. In Racing Mode, latency can drop as low as 15 milliseconds when paired with compatible goggles. This ultra-low delay enhances precision during high-speed maneuvers and technical racing environments.

Dual-antenna 2T2R technology strengthens signal reliability and extends the maximum transmission range up to 15 kilometers (region dependent). The system automatically selects the most stable frequency, helping maintain consistent connection in complex environments.

High-Frame-Rate Live View & Recording

The transmission system supports 1080p live view at up to 100fps, ensuring fluid real-time imagery inside your goggles. H.265 encoding optimizes bandwidth efficiency while preserving sharp image quality. For cinematic capture, the air unit supports multiple resolutions including 4K (16:9 and 4:3), 2.7K, and 1080p at high frame rates.

Electronic image stabilization via RockSteady 3.0+ improves footage smoothness in dynamic flight. Pilots who prefer gyro-based post-stabilization can disable EIS for compatibility with advanced editing workflows.

Compatibility & Integration

The DJI O4 Air Unit Pro integrates seamlessly with the DJI O4 Air Unit ecosystem and is fully compatible with the DJI Goggles N3. This ensures stable digital FPV experience with clear and immersive viewing performance.

The compact mounting pattern (20×20mm / 25.5×25.5mm) supports flexible installation in modern drone frames. Its wide voltage input range (7.4–26.4V) simplifies integration across diverse builds.

Professional Imaging Control

The camera supports D-Log M color mode for advanced color grading flexibility. ISO range extends up to 25600, providing adaptability in varied lighting conditions. Built-in 4GB storage and microSD support up to 512GB ensure ample recording capacity for extended sessions.
