What is an FPV aerial camera?
In recent years, with the rapid development of drone technology, FPV (First Person View) aerial photography cameras have gradually become a hot topic. This technology allows the operator to feel as if he is in the aircraft through real-time transmission of images, bringing an immersive flight experience. This article will introduce in detail the definition, working principle, application scenarios and popular products in the market of FPV aerial photography cameras.
1. Definition of FPV aerial photography camera
The FPV aerial photography camera is a real-time image transmission device specially designed for drones. It is usually installed on the front end of the drone and transmits the captured images to the ground receiving device (such as a display screen or FPV glasses) through wireless signals. This technology is widely used in aerial photography, racing, agricultural inspections and other fields.
