My advice/opinion If you don't value your life/you enjoy taking extra risks and choose to "open her up" at every opportunity then any camera (evidence) is going to be "down voted" If you ride with common sense (like many youtubers (TMF, Teapotone, Spicy110) then cameras are beneficial and do the job and it's very rare that "the evidence" is used against you I started out with the cheap Asian GoPro type 1080 cameras for £30 (if that) but batteries lasted only 45mins - additional batteries or more powerful batteries could be found for a few quid. They did the job (WiFi etc but no stabilisation) Best fitted to helmet to reduce potential vibrations and also because they are then pointed to where you're looking. I've now upgraded to the Ghost X on helmet with the former cheapo permanently wired under the Givi Monolock mounting plate as a rear view camera set as loop recording - as soon as the ignition is on the camera wakes up and starts recording - not too bothered about vibration so long as it catches the moment someone rear ends me...just in case Siting of the camera will depend on for what reason you want one. If it's "just in case" accident evidence then you'd probably want to fix it to your helmet and where on the helmet is mainly personal depending on you, your riding style and your ride. Very little wind turbulence will be noticed by many but the sporty, tucked down rider will probably notice much more. If you're well off and £300+ is pocket change then go buy a GoPro If you're a tight git like me and unsure - spend £30 and try it - if it does what you want then keep an eye out for Ghost X or equivalent for when it's on offer then snap it up then hard wire the cheapo to your tail tidy or nearby My helmet is also "flip front" - Ghost X fitted to side - Bluetooth comms fitted opposite side My previous helmet was same - but previous camera fitted to top of helmet (didn't like the side mount fitting option) HTH
