Add the rear view camera to your DVR-F800PRO for complete front and rear surveillance. The RVC-R800 is installed on the rear window to provide a wide viewing angle of the traffic behind your car. Record FHD-quality video and detect motion occurring at the back of your vehicle (if your DVR-F800PRO is hard-wired). Using the Alpine Dash Cam Viewer for PC or MAC, you can view front and rear videos simultaneously on a single display for more comprehensive assessment of an incident.
