A new level of freedom in video transmission
Powered by the modern DJI O4 video transmission system, the Pro version delivers outstanding smoothness and control feel during flight. With latency reduced to as low as 15 ms and long-range performance supported by dual antennas, you can enjoy a stable connection and reliable image feed when flying in open spaces or navigating more technical environments. The system automatically selects the best available frequency to help minimize interference and maintain a steady data stream with up to 60 Mbps bitrate.
Outstanding image quality for FPV flying
Thanks to the H.265 codec, the DJI O4 Air Unit Pro can transmit video at 1080p and up to 100 fps, giving you a clear, fluid, and highly detailed live view. Whether you are chasing speed, flying technical lines, or exploring new routes, the smooth image helps boost confidence, improve awareness, and make every session more immersive.
Racing mode built for speed and adrenaline
If racing is your thing, the enhanced Racing mode takes the excitement up a notch. Ultra-low latency gives you the precision needed for fast reactions and tighter control, while support for racing with up to eight drones at the same time opens the door to competitive fun, intense practice sessions, and serious FPV action.
Capture spectacular footage without an extra action camera
The DJI O4 Air Unit Pro is more than a transmission unit. It also lets you create stunning footage straight from your drone. The built-in 1/1.3-inch CMOS sensor records 4K video at 120 fps, delivering excellent detail and dynamic motion capture. A 155° field of view helps you frame sweeping landscapes and complex flight paths, while 10-bit D-Log M preserves more detail in highlights and shadows for easier color grading.
For smoother results, the system supports RockSteady stabilization, and if you prefer post-processing, it also works with Gyroflow for additional stabilization in editing. You can even use ND filters compatible with DJI Avata to better adapt your footage to changing light conditions.
Customize your view with Canvas Mode
With support for Canvas Mode and Betaflight OSD, the DJI O4 Air Unit Pro gives you more control over what you see in your goggles. Adjust the on-screen layout, choose the flight data you want to display, and build a viewing setup that fits your style. The result is a more intuitive, more personal FPV experience.
Compact build, flexible installation
Designed to stay light and versatile, the DJI O4 Air Unit Pro weighs only about 32 g with the camera module. Its compact form factor makes it suitable for a wide variety of FPV drones, from smaller custom builds to more advanced platforms. It is easy to install, easy to integrate, and ready for dynamic flying with full control over every move.
Wide compatibility with DJI FPV gear
The DJI O4 Air Unit Pro fits easily into different FPV setups. It works with DJI Goggles 3 and DJI Goggles N3, and can be controlled with the DJI FPV Remote Controller 3. It is also compatible with DJI Goggles 2 and DJI Goggles Integra when paired with the DJI FPV Remote Controller 2. That means more freedom to build the setup that works best for your flying style.
