This advanced model offers 4-channels each w/ 1080p resolution, which is a unique advantage not many dash cam owners can boast. You can eliminate all blind spots by setting up your camera to record your front, rear, left and right view as you drive. Or, you can choose to point the left and right cameras w/ built-in IR lights to capture your cabin view, making for a fully customizable experience. To take your camera to an even higher level, we recommend using our CPL filter to reduce the glare caused by street lights and headlights. ***If a hardwire kit was not included wih your purchase, please contact bbyhwk@rexingusa.com.
