DJI O4 Pro is a top-tier digital video transmission system for FPV drones. The set includes a camera, a transmission module, and two antennas. DJI O4 Pro delivers excellent video transmission in 1080p resolution at 100 frames per second with a bitrate of up to 60 Mbps. The unit also allows onboard video recording in up to 4K resolution at 120 frames per second. Recorded footage can be stored on the internal 4GB memory or on a microSD card with a capacity of up to 512GB. For advanced users, a 10-bit D-Log M color profile is available for later color grading. Image stabilization can be applied either instantly using DJI Rocksteady or later with Gyroflow. For racing enthusiasts, the Racemode offers ultra-low latency of just 15 ms. The video transmission also supports Canvas Mode, allowing the use of classic OSD layouts from the flight controller. The unit can be powered by a 2–6S Lipo battery (7.4–26.4V).
The transmission module has M2 mounting holes with a spacing of 20x20mm and 25.5x25.5mm. The FPV camera uses non-standard mounting holes with a 12mm spacing, so it is important to verify that your frame is compatible with the camera.
DJI O4 Pro is designed for use with DJI Goggles 3 or DJI Goggles N3 and the DJI Controller 3.
DJI O4 Pro can also be used with DJI Goggles 2 or DJI Integra together with DJI Controller 2. However, in this case Racemode is not available and the maximum bitrate is limited to 50 Mbps.
