I demoed a VholdR Countour HD camera from my work and took it for a ride at Salem Hills with my dog Calvin. It’s a “lipstick” style camera so there is no video screen to see what exactly you are capturing.  The model I used produced HD quality video with a 1280×720 resolution, not bad for something that will set you back less than 300 dollars. I had limited options when it came to mounting the camera but looking online it appears that you can purchase a number of different mounting solutions. I think adding a simple tripod mount to the bottom would have been ideal.
I put this together in about an hour or riding and then another hour of editing in Apple’s iMovie.
