About this item Applicable toIf the length of the 4Pin backup camera cable or the dash cam rear view camera cord is insufficient, please choose our 4Pin backup camera extension cable to increase the required additional length, allowing for easy and flexible wire management in tight spaces. Pure Copper Thicker Shield Dash Cam Extension CableThis dash cam rearview extension cable uses pure copper with a diameter of 3.5mm thick wire (most original rear camera cables are 2.8mm). The thicker wire includes a shielding layer to minimize signal loss, ensuring optimal video clarity. Multiple Length OptionsThis 4Pin mirror camera extension cable can be ordered in various lengths: 5ft, 10ft, 15ft, 20ft, and 25ft. A shorter cable generally provides a more stable signal; therefore, we recommend selecting the most suitable length for your needs. NoteThis is a 4pin dash cam rear camera extension cable. Before ordering, please confirm that your backup camera wire plug matches the 4pin plug. Test This
