A few people asked us if we use the GoPro for our FPV live stream too. As this is possible using the live out of the GoPro, i would definitely not recommend that. First of all, the low light and back light picture quality of the GoPro is inferior to most of the CCTV cams out there. Second, as the GoPro records in 16:9 and most of the goggles out there show 4:3, you will get those ugly black bars at the bottom and top of your picture. The last thing is, that if your GoPro shuts down, for whatever reason, your video will be gone. Next Problem is the photo-mode. Every time the GoPro shoots a photo, the Live-Out will show you a black frame for ~1 second. So the way to go is getting a nice CCTV camera.
If you are new to FPV or are looking for a cheap camera, which is just plug and play, but still offers a good picture, than I recommend the Sony 420TVL CCD camera. It’s only 24$ (17.80€)(shipping included) and ships with a 3.6mm lens. This yields an effective field of view of 60 degrees. You should replace the lens with a 2.5mm, which will give you approximately 120 degrees FOV and makes your picture less shaky. This camera outperforms the hobbyking CCD camera easily. I didn’t try any CMOS cameras in this price segment yet, as I’m generally skeptic about CMOS, because of the rolling shutter effect. If you have any experience with CMOS cameras up to 20$ please drop a comment 😉 Here is a little video i made with the Sony 420TVL CCD camera.
If you want a higher contrast-range and a configurable backlight compensation, i can also recommend the SONY Super HAD WDR CCTV cams with OSD board:
This is of course for the advanced FPV pilot who really wants to engage in the hobby. It costs 53$(39€) shipping included.
