The O4 video transmission system adopts an all-new hardware solution, first introduced for DJI Air 3, RC-N2 and RC 2 Smart Controller.

The aircraft antenna system is upgraded from four antennas to six, and a new frequency band* has been added.

The communication algorithm has also been upgraded, which not only delivers an FHD video transmission from a max range of 20 km**, but also features enhanced anti-interference capabilities, further improving the transmission stability in complex environments like urban settings.

O4 remote controllers also supports a 1080p/60fps max real-time live feed, with the higher frame rate delivering a smoother viewing experience.

* Can be used only in countries and regions where it is allowed by local laws and regulations. ** Measured in an open outdoor environment without interference and with FCC compliance. The above data shows the farthest communication range for one-way, non-return flights. Always pay attention to reminders in the app during your flight.
