I just started a similar thread on 1000RR.net
Im after an onboard camera for my racebike, but havent seen many that I think are up to the job...
Im after something that has its own recording device as I dont want to connect to a camcorder.
I have been looking at Elmo SUV-Cam
http://www.elmo.co.jp/suv-cam/en/index.html
But every vid on there site seems to have buffering problems (software?) even once downloaded and saved to my HDD also the frame rate seems a little low (25fps) as you get the effect of the wheel turning backwards (check their Harley drag bike). This camera would be exactly what Im looking for if the video quality wasnt suspect?
Also looking at this one
ATC2K it does 30fps, but the only thing I want is to be able to add a remote mic so I can place it out of the wind and closer to the exhaust

It has an inbuilt mic but not sure if an auxillary one can be added?
Does anyone have any other suggestions?
