The camera is an important part of your drone's FPV system. The FPV camera currently used are analog and digital mini cameras that transmit the image relatively latency-free to your ground station (video glasses or FPV receiver). An Action Cam (GoPro) is not latency-free and is therefore only suitable as a second camera for video recording on race copters or can be used in video quadrocopters. There are a few things to consider when choosing your purchase. FPV cameras differ in some points. Basically there are analog and digital cameras. Meanwhile there are some models that can Full HD with frame rates of 60fps. There are FPV cameras that also record via an external SD card. The size and weight also play a relevant role. The latency describes the delay from live action to the video glasses or ground station - the lower the latency the better. FOV means Field of View, here the opinions differ a little bit, some FPV pilots prefer smaller and others larger fields of view. For your FPV racer we recommend a camera with a 2.5mm FPV lens for an optimal field of view.
