I am an over the road truck driver and want to set up a dash cam for liability reasons, among other reasons. I know the Video Copilot is used as a dash cam for this reason and records over 24 hours, re-recording over the oldest five hours as it goes along. I am trying to compare the Video Copilot with the Go Pro and with the Contour but I have not found alot of information for comparison. Can I mount the gopro on my dash and hook up the USB to my cigarette lighter adapter, and use it for approximately 11 hours in a day. Thats about how long my trips are including stops. Please someone give me insight and detail on this Gopro or any other and what additional I should buy with it. Thank you ahead of time for your help in figuring out what to buy and use.
