front and rear dash cam use with a cap

Instead of picking up a dual cam with the smaller rear cam and trying to run the wire from the front cam in the cab (2021 Tacoma) to the rear cam inside the cap, would it just be easier to pick up two single dash cams and hard wire the one in the rear? Became a believer in the cams after a coworker who has one was in a fender bender and seeing the video.
