I still think you should look into putting the camcorder on a suction mount, you get 100% quality then.

The DogCam look good, but as Patricks says it's a little overpriced and maybe over spec'd for what you want. I don't like the suction mount much, those small suckers are no good in wet conditions as they can't keep the seal, you need one with a pump on like the models I linked to above, although the one I have needs quite a flat body panel to suck onto.
