Review: Good cable - Works well and is perfect to extend my backup camera wire, good price, good length and decent price
Review: No signal attenuation with 20ft line. Works great - I was uncertain about signal attenuation due to the length but I installed the 20ft cable to extend my line for a long body Sprinter van. Zero issues. Note, if you have the additional red wire that goes to your backup lights to trigger the backup camera automatically, you'll need to extend that separately. One butt splice and a few feet of 16ga wire and you're good. I do wonder why I couldn't just find a tip/ring extension line at the end nearest the head unit though.

## Features

- 【Applicable to】If the length of the 4Pin backup camera cable or the dash cam rear view camera cord is not enough, please choose our 4Pin back up camera extension cable to increase the required additional length, making it easy and flexible to neatly hide the wires in nooks and crannies.
- 【Pure Copper Thicker Shield Dash Cam Extension Cable】This dash cam rearview extension cable use pure copper with a diameter of 3.5mm thick wire (most of the original rear camera cables are 2.8mm). Due to the excessive extension, we must use thick wire with a shielding layer to reduce signal loss, otherwise the video clarity will be reduced.
- 【Multiple Length Options】This 4Pin mirror camera extension cable can be ordered in different lengths: 5ft. 10ft. 15ft. 20ft. 25ft. The shorter the cable, the more stable the signal. We suggest that you choose the most suitable length of cable.
- 【Note】This is 4pin dash cam rear camera extension cable. Before ordering, please check your backup camera wire plug to ensure it is the same 4pin plug. We are a professional company of production dash cam accessories cable. If you need 5pin, 6pin and 8pin mirror dashcam rear view extension cables of different lengths, please search for 'YQMAJIM'.
- 【Test This Back Up Camera Extension Cord Before Wiring】Before installing this reverse camera extension wire, please first test whether it suitable for your device.

### ⭐⭐⭐⭐⭐ No degradation of video quality
*by J***B on January 12, 2026*

Used the 20' version of this extension cable to place a rear-view camera at the back of my motor home. Works excellent. No reduction of video quality combined with the 18' cable that came with the CarPlay Screen unit I mounted on my dash.
