Today's Dashboard Cameras provide many features for drivers. First and foremost, they record everything that happens while you are driving (some even offer rear cameras so front AND back are covered). This can be of great assistance in accidents, road-rage incidents, and more.
But some of these modern Dash Camera packages even record in "Park Mode" (similar to Tesla's "sentry" mode). This can be an incredible theft deterrent (similar to having camera's in your home or business). Advanced models even have built-in G-Sensors which will "wake up" the system if they detect that the vehicle has been bumped. The footage will be VERY helpful in hit-and-run situations.
With models starting at only $99, there is no reason not to own one. Whether for fleet vehicles, teen drivers, or your personal safety-dash camera's are an integral part of today's safe driving.
