red1 i've got a mini dvr set up from dogcam which gives excellent results, you can see exactly what u r shooting as the cam attaches to a small digital recorder with a screen. The recorder is'nt waterproof but the cam is, i put my recorder in the clear pocket of my tank bag to see what i'm filming. It also comes with a remote button so you can stop and start filming on the move, battery life on my recent trip was around 3 1/2 hours of actual filming, you can charge from the bike so effectively you are only limited by the size of the memory card. The only downside is the remote goes into the same socket as the charger so it's one or the other
