perfect 128 GB SD card for a dashcam

Bill from Stephens City, VA on 5/6/2018

Crutchfield Customer Review (What's this?)

Based on Scott Thompson's (Harrisonburg, VA store manager) recommendation I purchased a Papago, Gosafe S37 Dashcam to record videos of our pending drive of the Alaskan highway later this summer. We drove the highway two years ago and I to record the scenery and wildlife along the highway. I told Scott that I wanted 1080P resolution, 128 GB capacity and a 140 degree wide angle lens. The S37 meet all of my criteria. I installed a Samsung 128 GB micro SD card and used the dashcam on a trip to Ohio. But, when I played the video back I noticed that the video was not all that brilliant, it was clear but dim. I assumed it was due to driving into the sun. However, when I stopped by the Harrisonburg store, to show Scott the camera and video, I noticed that the lens was covered with a clear protective plastic cover. After removing this plastic protective cover, remounting the dashcam and driving home I played the video on our 75 inch Samsung 4K TV. Wow!!! The quality of the video is amazing. The video is clear, crisp with just a little blur at the extreme right and left edges of the video. That 140 degree wide angle lens does an amazing job of recording the road and berm on either side of the highway. This is the perfect dashcam to record Alaskan wildlife along the highway and the scenic beauty of the terrain. The 128 GB micro SD allows for a couple of days of driving without fear of overwriting recorded video. Take two 128 GB cards on

Pros: The 128 GB micro SD allows for a couple of days of driving without fear of overwriting recorded video. Take two 128 GB cards on your vacation trips. That amount of date will allow one to, at their leisure, select and copy video to their PC or a thumb drive.

Cons: none
