Watching Tesla Dash cam footage it seemed handy to have driver/passenger side footage. The 3 and 4 camera devices on the market seem to lose recording quality above 2 cameras. Also did not want to add a blindspot from a larger multi cam unit on the windshield. 2k Viafo forward camera with second camera out the back. Used the Motorcycle Dash cam attached to headrests for side footage. Initially bought the attachment for windshield unit to use the powered rear view mirror power. Might use the adapter on wife's 4runner. Ran USB power to below driver seat. Will likely add Dashcam battery below driver seat for standby recording. Daughter is in college. If I had kids using the rear seats daily would have used the rear port windows. There are empty spots in the FM radio antenna. While downloading footage I grabbed one that's out of sync. Used 256gb Samsung memory cards.
