Are the front/rear connecting cables the same as the A129 series?Updated a year ago

No, the VIOFO A139 3-CH uses different coaxial cables as the A129 series.

If you are thinking of upgrading to the A139 3CH from the A129 Plus or other VIOFO dual-channel systems, you will need to replace all the existing VIOFO cameras and cables.

New Power Cable

The A139 uses a USB-C power cable with a smaller, reversible connector, which is entirely different from the power cable used by other VIOFO models. If you are planning on hardwiring the dash cam, you will also need to grab a new hardwiring kit as the old hardwiring cable won't fit into the power port on the A139 3CH.

New Coaxial Cables

The A139 3CH uses an ultra-slim coaxial connecting cable with miniature connectors for the interior and rear cameras. Again, these are also entirely different from the coaxial cables used by other VIOFO dual-channel models.

New connection ports

The connection ports on the A139 3CH front camera’s face will be different from those found on other VIOFO dash cams because of the new coaxial cable and connectors. In other words, the A139 3CH front camera will only work with the A139 rear and interior cameras, and vice versa.
