4. Adjust the angle of the lens by rotating the body of the front camera. We recommend pointing the lens slightly downwards (≈10°below horizontal), so as to record video with a 6:4 road to background ratio.

5. Fasten the rear camera mounting bracket using the included screws to the top of the back of the vehicle.


6. Connect the front camera (‘Rear’ port) and the rear camera (‘V out’) using the rear camera connection cable.

•  If the waterproof coaxial cable is mounted externally, we recommend covering it to secure it in place and protect it against the elements.

7. Use the pry tool to lift the edges of the rubber window sealing and molding and tuck in the rear camera connection cable.

8. Plug the cigarette lighter power cable into the cigarette lighter socket and the front camera. Skip to 12 for Hardwiring Power Cable setup.
