Thank you for viewing. This is a set of a rear camera for a drive recorder, a power cord, and a glass mounting attachment. The camera's connector is a 3.5mm plug. The attachment's screw thread is M4-0.7. The power supply is USB mini B. All items are brand new and unused. It can also be used for a backup camera. If you connect the red wire to the reverse signal, guidelines will appear. Thank you for your consideration.
