Everything you need to know to understand First Person View drones
FPV (First Person View) is a method of piloting a drone where the operator sees exactly what the drone's onboard camera sees in real-time, through specialized video goggles. This creates an incredibly immersive experience—you feel like you're sitting in the cockpit of a tiny aircraft.
