Introduction

DJI Digital FPV System

The DJI Digital FPV System consists of the DJI FPV Air Unit, DJI FPV Goggles, and DJI FPV Remote Controller, featuring the DJI HD Low Latency FPV Transmission, to provide an integrated video transmission with high definition and low latency for racing flight. The DJI Digital FPV System supports a 5.8 GHz digital video signal and 720p 120fps image transmission, with a transmission range of up to 4 km and a minimum end-to-end latency within 28 ms*. Up to eight fixed channels are supported**, and the enhanced anti-interference ability greatly improves the smoothness and stability of the video transmission. The DJI Digital FPV System integrates a camera, video transmission, display view, and remote control to provide a high-quality racing experience.

Typical Application Scenario

The DJI FPV Air Unit includes the air unit module and camera, which can be mounted on a racing drone and used with the goggles or a remote controller to transmit video, control signals, and flight controller information wirelessly.

The DJI FPV Goggles are equipped with a high-performance display and support 810p 120fps HD display. When used with a racing drone equipped with the air unit, users can enjoy a first-person view of their aerial experience in real time.

The DJI FPV Remote Controller works with the air unit and goggles, and can be used to control the aircraft and operate the menu screen of the goggles to set parameters.

*The end-to-end latency is the total time from camera input to screen display. The DJI Digital FPV System can reach its minimum latency in Low Latency mode (720p 120fps), and achieving maximum transmission distance (FCC) in a wide open area with no electromagnetic interference. The aircraft will fall if the video or control signal is disconnected. Be careful when flying at low altitudes and long distances.

**There are up to eight channels for the DJI Digital FPV System depending on the region (FCC: eight, CE/SRRC: four, MIC: three). Each channel has a bandwidth of 20 MHz. The public channel is 8, which is the default channel when the equipment is powered on. The channel can be changed manually to avoid interference from other devices.
