What is Video Transmitter (VTX)？
A Video Transmitter (VTX) is an electronic device used in FPV (First-Person View) drones and other radio-controlled vehicles to wirelessly transmit real-time video footage from the onboard camera to a receiver, such as FPV goggles or a ground station monitor. The VTX converts the video signal into a radio frequency (RF) signal, allowing pilots to see the drone’s perspective in real-time.
