Considering the ever increasing number of dangerous, unlicensed, unregistered, and uninsured drivers in my area, I've decided to install dash cams in both my, and my wife's vehicles. Problem is, I know nothing about them. I did a quick search on Amazon and there seems to be a lot of choices in the $29 to $129 range. Then the prices seem to shoot up from there to the $300-$500 range. I'm guessing I don't need the 3-$500 ones as they probably have a bunch of bells and whistles I don't need. I could probably easily get by with one from the first price group. Any recommendations on which ones to look at, what features to look for, etc?
