Reliable transmission and low-latency control
The DJI O4 Air Unit is made for pilots who expect a stable connection and responsive control. With latency as low as 20 ms in selected Racing mode configurations and a video transmission range of up to 10 km (FCC), this system helps you stay locked in when speed and precision matter most. It’s a great fit for both high-intensity FPV sessions and smooth recreational flights.
Smooth, detailed FPV live view
Experience immersive flight with 1080p video transmission at up to 100fps, powered by the efficient H.265 codec. The result is a clean, fluid image with plenty of detail, even during fast maneuvers. If you enjoy dynamic FPV flying, freestyle runs, or precise line control, this setup delivers the visual feedback you need to react quickly and fly smoothly.
Built for racing excitement
If speed is your thing, the DJI O4 Air Unit is ready for race mode action. With ultra-low latency and support for competitive FPV scenarios, it helps keep your feed responsive when every split second counts. You can even race with up to eight drones at the same time, making it a strong choice for pilots who want more adrenaline and more competitive fun in the air.
Capture sharp 4K footage on every flight
The integrated camera module with a 1/2-inch CMOS sensor lets you record detailed footage in 4K at 60fps. Whether you're chasing cinematic lines or collecting clips from your latest freestyle session, the DJI O4 Air Unit gives you high-quality onboard video without needing extra recording gear. RockSteady 3.0+ helps reduce shake during aggressive maneuvers, while Gyroflow support gives you more stabilization options in post.
Custom OSD with Canvas Mode
Set up your screen the way you like it. Thanks to Canvas Mode compatibility, the DJI O4 Air Unit works with Betaflight OSD so you can customize the layout and on-screen flight data shown in your goggles. Voltage, speed, battery status, and other key information can be placed exactly where you want it for a more personalized FPV experience.
Compact size, big FPV potential
Weighing only 8.2 g with the camera module attached, the DJI O4 Air Unit is an excellent option for lightweight and smaller drone frames, including 2-inch builds and below. Its compact footprint makes installation easier in tight builds while helping keep your aircraft agile and efficient in the air.
Broad compatibility with DJI FPV gear
The DJI O4 Air Unit integrates smoothly with selected DJI goggles and radio controllers, making it easy to match with your preferred FPV setup. It supports combinations including DJI Goggles 3, DJI Goggles N3, DJI Goggles 2, and DJI Goggles Integra, along with compatible DJI FPV remote controllers. It also supports Betaflight 4.3.0 and newer flight controller systems for flexible setup options.
Looking for even more? Meet the DJI O4 Air Unit Pro
For pilots who want a more advanced setup, the DJI O4 Air Unit Pro pushes performance further with a larger 1/1.3-inch CMOS sensor, 4K/120fps recording, and an ultra-wide 155° field of view. It also supports 10-bit D-Log M for better color flexibility, while the dual-antenna design enables transmission up to 8 km with latency reduced to as low as 15 ms in supported conditions. It’s a strong upgrade path for demanding FPV creators and racers.
