Here are some videos in various lighting and driving situations that I took using the Street Guardian SG9663DC Dash Cam. It’s a dual-lens (front-and-rear) dash camera that records in 1920×1080 at 30 FPS. I think it has the best video quality of any dual-lens dash cam out there right now. You can buy it on Amazon here.
The first two videos were sub-par because I left a fingerprint on the polarizing filter during installation. Cleaning the filter and the lens cleared that up — literally.
