2019 Honda Insight EX (White Orchid Pearl)
Are they replacing the back one? Did the static noise end up being the camera itself, rather than wiring path as you originally suspected?
The replacement usb cable I bought had a ferrite core but it didn't solve the problem. After reading the below quote from the dashcamtalk forum I went and bought a 22 AWG usb cable. That didn't fix the problem either. The front one(same model) works with all 3 usb cables(the original & both replacement usb cables) without any static noise created. I told Viofo about it and they agreed to replace the defective dashcam.Does your mini-USB cable have a cylindrical shaped ferrite bead attached to it? It helps remove static. The hardwire kit that I purchased came with it.
Viofo cameras, including the A119 V3 ship with 22 AWG USB-A to Mini-B power cables, unlike many other cameras on the market that often ship with either a 28 AWG or 24 AWG cable. While I'm not certain about the V3, other cameras such as the A119 V2 tend to experience problems if the wire gauge is too thin such as flickering screens and occasional low voltage audio artifacts (pulsating buzzing) in the videos.
