I've been running two A119V2 cameras ( front and back) and powering them through the 12V sockets in my car. All good, no issues.
Today, I hardwired the front camera using a "Dash Cam Store" install kit (http://www.thedashcamstore.com/dashcam-installation-kit-5-volt-usb-plug-mini-fuse/). I tried various switched locations in my fuse box for the tap.
In every case...I get lots of static on AM radio stations. If I the unplug cord from the camera, the static stops immediately. I never had any problems with the same camera when running off of the 12V, so it is obviously being caused by the hardwire install.
It's not a big deal, just curious if there is anything I can do to resolve it. I've read posts suggesting adding snap on ferrite core rings to the the USB cable. Anyone have experience with this?
If so...am I correct that I'd position the rings at the "start" (i.e. next to the transformer) and at the "end" (i.e. near the camera itself)?
