For FPV pilots, a crystal‑clear live view and minimal latency are non‑negotiable. DJI’s latest O4 Air units bring that precision to the next level, offering 1080p/100 fps live feeds and sub‑20 ms transmission over distances that rival the industry’s best. Whether you’re racing or shooting cinematic footage, the O4 line removes the need for an external action camera, simplifying your rig and reducing weight.

Below, we break down the core differences and help you decide which unit best fits your setup.
Sensor Performance
The Pro’s 1/1.3‑inch sensor delivers larger pixels and superior low‑light performance, making it ideal for cinematic work. The standard unit’s 1/2‑inch sensor still offers excellent clarity for racing and freestyle flying.
Video Capture Capabilities
With a 155° ultra‑wide view and 4K/120 fps recording, the Pro unit is designed for high‑frame‑rate filmmaking. The standard unit captures 4K/60 fps across a 117.6° field, suitable for most FPV scenarios.
Transmission and Latency
Both units use DJI’s O4 protocol and share a 60 Mbps bandwidth. The Pro’s dual‑antenna architecture provides 15 km range and 15 ms latency, outperforming the standard unit’s 10 km range and 20 ms latency.
Compatibility with Goggles and Controllers
All O4 Air units pair seamlessly with DJI’s lineup of goggles and the FPV Controller 2 and 3, ensuring a smooth workflow across DJI ecosystems.
