Core Components of FPV

Camera: Installed at the front of the aircraft or other critical locations, it is responsible for capturing the flight perspective. Depending on the application, cameras are categorized into analog cameras (low latency, low cost, suitable for racing) and digital cameras (high image quality, strong interference resistance, suitable for aerial photography).
Video transmission module: Wirelessly transmits the image signals captured by the camera to the receiving end. Common frequencies include 2.4GHz and 5.8GHz (5.8GHz is the mainstream choice due to its wider bandwidth and lower interference).
Receiver Module: Pairs with the video transmission module to receive wireless signals and convert them into image signals, which are then connected to a display device.
FPV Goggles/Display: The operator's “viewport.” Goggle-style devices (such as DJI FPV Goggles or the Fat Shark series) offer a stronger sense of immersion, while displays are suitable for multi-person viewing or educational scenarios.
Flight controller and remote controller: Ensure stable flight and precise control. FPV racing or穿越机 typically use high-response flight controllers (such as the Betaflight system) and low-latency remote controllers (supporting protocols like SBUS and ELRS).
