For FPV you need a way to take (and maybe record) video, transmit video, and view video. You need a video transmitter and a camera to go on the quad, a receiver and play-back device like a screen or goggles on the ground. Quantum V2 Goggles (unless you want a screen) or another set of goggles like headplay or fatshark (Never get the Teleporters). Eachine googles ~60$ goggles cheaply made and a lot lower res than the quantums, but the price is almost 40$ less 148 FOV camera+ 32ch 200mW VTX (message me or Neil as we may be able to get this set 50% off) or if your budget is really tight then here is a cheaper set I have used and like. The camera is not as wide a FOV. 8ch Boscam receiver Don't forget a battery, I suggest getting around a 1000mAh 3S battery for the Quantum. And FPV is not near as fun when you are not recording it so I suggest the Runcam, I have used it and am really surprised with the quality, especially for the price. --NEW-- Sky-HD01 all in one camera, Like Runcam or Mobius, but built in vTx and low latency, remember you can't fly FPV from a gimbal, so if you want to you need two separate cameras. DVRs in case you wish to record your video stream:| Cheap DVR from Banggood 24$Better DVR from Hobbyking 52$ Bosscam pocket ground station from Hobbyking 100$ 32ch receiver with built in DVR from Hobbyking 45$ If you are planning on adding FPV to a mini then be sure to check out this skyzone 4.5 gram 5.8GHz FPV camera and transmitter from flitetest. Suggested link for the Fatshark DOM V2. If you want some steady video here an Eachine 2 axis gimbal. Out of the box it works with the GoPro, but you can make it work with a Runcam or Mobius form factor pretty easy, just message me for the file.
