DJI has unveiled its next-generation O4 Air Unit Pro Drone System, featuring the innovative O4 transmission protocol.
This new video transmission system elevates first-person (FPV) drones to new heights, providing more precise controls, ultra-low latency, and an extended transmission range.
The camera has also received significant upgrades.

“FPV enthusiasts will be thrilled with the stunning visuals they can capture using the O4 Air Unit Series,” said Ferdinand Wolf, Product Experience Director at DJI.
“The O4 Air Unit Pro provides a robust, high-performance FPV experience, regardless of how fast you fly, while the O4 Air Unit offers flexibility in a lightweight and adaptable form, making it compatible with various DJI Goggles and FPV Remote Controllers.”
Equipped with a dual antenna array, the DJI O4 Air Unit Pro boasts a maximum transmission distance of up to 15 KM (10 KM for the standard model) while maintaining a stable connection with one-third less latency than the previous model.
The unit also includes an advanced camera module that captures and encodes 4K video at 60 fps in H.265 format, along with high frame rate transmission of 1080p at 100 fps for clear, smooth, and near-real-time video signals.

The camera transmission has been tested for latency as low as 15 milliseconds.
It features a 1/1.3-inch image sensor (1/2-inch for the standard model) that records 4K video at 120 fps with a 155° ultra-wide-angle lens, delivering minimal distortion.
The O4 Air Unit Pro camera supports the addition of the DJI Avata 2 ND filter set, which includes ND8, 16, and 32-stop filters.
This set ensures balanced exposure and accurate, true-to-life colors while controlling light intake and shutter speed, creating a natural motion blur for more cinematic footage.
The O4 AUP flight system fully controls home-built FPV drones using Betaflight OSD and Canvas mode settings.
Users can customize real-time data readouts displayed on FPV goggles, such as the DJI Goggles 3, and receive flight metadata for real-time drone control.
The system automatically cycles through and selects the most stable frequency available, providing pilots with up-to-date telemetry to confidently fly the drone to its maximum distance while delivering crisp, real-time imagery regardless of speed.

Designed for versatility, the O4 Air Unit Pro weighs just 32 grams (including the camera module) and measures 33.5 x 33.5 x 13 mm. In contrast, the standard O4 Air Unit weighs only 8.2 grams (camera module included) and measures 30 x 30 x 6 mm.

Both units are suitable for a wider variety of custom FPV drone builds, with the O4 Air Unit Pro recommended for drones three inches and above, and the standard O4 Air Unit suitable for drones two inches and below.
They are compatible with both the DJI Goggles 3 and Goggles N3, and they remain backward compatible with DJI Goggles 2 and Goggles Integra.
Furthermore, when attached, the units can pilot drones using DJI’s FPV Remote Controller 3 and FPV Remote Controller 2.
Pricing and Availability
The DJI O4 Pro Air Unit retails for $229 and includes two antennas, the 1/1.3” 4K camera module with 4GB of onboard storage, and the O4 Transmission Module.
The standard O4 Air Unit is priced at $109, coming with a single antenna, a standard transmission module, and a 4K 1/2-inch camera module featuring 23GB of onboard storage.
FPV goggles and remote controls are sold separately. Available from DJI Direct and its authorized dealers.
