Dash Cams: The Good; The Bad & The OMFG!
 

There are many types & qualities of driving cameras that record while you drive.
Basic ones that you'll find online will give you from basic and shitty pictures to 1080p, HD quality that record while you're away from your car and that automatically upload their information automatically when you get home every night that also act as crash deterrents.
Some will even offer you 4 cameras for every aspect of in car security with a hide away DVR.
There are as many combinations as there are qualities. The big question is: what are you willing to pay for the quality & options available? I've seen them as low as $23 and as high as $4000.
I would suggest visiting one of your local car stereo shops to see what the best options for you are.

Our current offering creates more road safety by making you aware that you're weaving out of your lane. It makes it much easier to be a distracted driver. It also allows you to to "wake up" before you crash.
