A 4K rear camera, such as the F77 dash cam, offers much clearer footage and performs exceptionally well in capturing dynamic elements, especially license plates, even at night.
Another option is to mount the rear camera outside, above the license plate. Without the interference of a windshield, this setup maximizes the recording angle and clarity.
