The Digital FPV Experience Combo from DJI is designed to provide up to two drones with the ability to stream first-person video for drone racing, aerial cinematography, and more. Usable on aerial drones and other RC vehicles, it includes FPV goggles and two Air Unit Modules with HD cameras. The system is engineered to deliver 720p120 HD FPV footage at a low, 28ms latency from up to 2.5 miles away. The goggles and air units come pre-programmed out of the box to work together, making setup easy. With an embedded remote receiver in each air unit, the addition of a remote controller (not included) can give you camera and flight control.
