Thank you Kamkari1. I was tapping on the little window on the screen that shows the rearview camera. When I tapped on it, the rearview camera fills the whole screen. For some silly reason I thought I was turning the rear camera on. When I watched the recording of the video on my laptop, I thought I was seeing the rearview camera because I turned it on by tapping on the screen.
I should have figured this out, I didn't. What probably threw me too, my Whistler 2000s shows a split screen. The Whistler is one camera with dual lenes. The recording is still one camera. The Nexbase 422gw is a little more sophisticated. I don't mind the two seperate files. The rear camera is recording, I'm happy with that. I was suprised the video from the rearview camera is pretty good. The whistler dashcam with the dual lenses works for a back window on a pick up truck. You still see the cabin. The whistler with the dual lenses will only see the cabin on an suv, it won't see out the rear of the car at all. The Nextbase with the rear view is a nice way of capturing outside the rear of the car. Probably not as good as putting a camera at the rear of the vehicle, a lot less of a hassle running wires and taking the back camera out. Don't want to leave the cameras in the car when it's unattended. In these parts of the woods they would break a window to take the camera. I said a lot not related to the original post. I thank you very much for responding and clarifying the files on the camera. Much appreciated.
Have a great day.
