Re: In car Camera - any one with experience.
We use an Adrenaline in car camera in our off-road car with a 32 gb card which gives us about 2 hours of recording time in 1080 hd. This type of system can be mounted virtually anywhere on the vehicle and is water and dustproof.
Probably more than what you're looking for, but it's an awesome system from my experience.
I made my first helmet cam with my Canon camera in it's waterproof case mounted on some disassembled tripod parts.
