DJI O3 Air Unit FPV Transmission System

An FPV camera and video link for your custom drone build

A DJI O3 Air Unit for hire: a compact 4K FPV camera and O3+ transmission module that drops into a custom FPV drone build to deliver low-latency HD video to your goggles.

The DJI O3 Air Unit is an FPV digital video transmission system, a single module that combines a camera and a video link for custom or DIY FPV drone builds.

It pairs a 1/1.7-inch image sensor with a 155 degree field of view and an f/2.8 lens, and records up to 4K at 60fps onto 20 GB of built-in storage.

While it records, it streams a live 1080p feed to your goggles over DJI's O3+ digital link, which reaches up to 10 km with latency as low as 30 ms and H.265 encoding up to 50 Mbps.

Signal is handled by 2T2R omnidirectional antennas for stable reception in busy conditions, and the whole module weighs only about 36.4 g.

This is a component, not a finished aircraft. It is fitted into an FPV drone that supplies the airframe, motors, flight controller and battery, and it feeds video to a set of compatible DJI FPV Goggles.

It takes a DC power input in the 7.4 to 26.4 V range from your build's power system.

It suits experienced FPV builders and pilots who want DJI-grade 4K capture and a long, low-latency HD link on a lightweight cinematic or freestyle build.

If you are assembling or upgrading an FPV rig for aerial work, this is the video heart of it.

The rental pack is the air unit, an antenna set and a coaxial cable, tested before dispatch so it is ready to install on the day.
