For video stuff I can't highly recommend the Chasecam PDR and cameras. They are a bit more pricey the a camcorder, but I think worth every penny if you want a reliable device, also have some neat add on extras like GForce and PIP processor. Also get a good bullet cam, some of the security ones are so-so. For mounts if you have a roll bar one of the better ones and not too expensive is from I/O Port racing. It is good for camcorders, but might be a bit overkill for lipstick cams.
