DJI O4 Air Unit Pro

The DJI O4 Air Unit Pro brings DJI's flagship digital transmission and high-resolution imaging to freestyle, cinematic, and heavy-lift FPV builds. Built around the advanced O4 architecture, this full-size unit provides an ultra-low-latency video feed to the pilot alongside robust 4K onboard recording, often eliminating the need for a secondary action camera on cinelifters and professional rigs.

Key features

• Utilises the DJI O4 transmission protocol for exceptional signal penetration and class-leading range.

• Records 4K flight footage directly to the air unit, streamlining cinematic workflows and saving overall build weight.

• Full-size "Pro" module format designed for optimal thermal dissipation in mid-to-large FPV frames.

• Transmits a smooth 1080p live video feed to the pilot's goggles at high frame rates.

Ensure your drone frame offers adequate mounting space and cooling airflow for a full-size digital VTX. Video link: pairs with DJI Goggles 3, Goggles N3, Goggles 2 or Goggles Integra. Control link: a separate choice — the DJI FPV Remote Controller 3 or 2 (through the air unit over SBUS), or any third-party radio through its own receiver on the flight controller. It is not a drop-in swap for an O3 Air Unit: DJI states the O4 camera and transmission modules differ in size.
