Dashcam Interference.
My drivers mirror mounted dashcam is causing terrible interference with my DAB signal, to the point where the signal drops out completely. Any ideas anyone?
Thanks Heddy |

Cheers, will try that as a last resort, been looking at ferrite coils to wrap around the wires or a type of shielding.

The Nextbase clf pointed out is about as good as they come if you need to re route the supply, and upgrade it.
If you are going to try FC's, buy 5 cores and attach them as close to the camera as possible, adding them one at a time.

I should have stated though, prior to spending money on anything, unplug the lead from the dash cam, to see if that improves, whilst the lead is powered up. If it does improve things, a ferrite coil is unlikely to help. If it doesnt change, a ferrite coil may help, but rerouting may also help too - but a quality power supply would almost certainly eliminate it. Moving the DAB aerial may also help too. Keep in mind, with a DAB signal being digital, it will drop out to silence if there is interference. (it is I/O or on/off).

Ah, so a dedicated power source for the dashcam may well be the way to go. The DAB signal drops to zero with the dashcam on, when the dashcam plug is pulled, the DAB signal returns as soon as the camera powers off.

I do think that it could be a combination of issues, from the lighter socket, power source and possibly the vicinity of the DAB aerial/power (even more so if the DAB system is an external type also powered by the cigarette lighter socket). Ultimately a decent external power source for the dashcam will improve things, whether it eliminates it I cannot guarantee. But they have electrical smoothing capabilities built in to limit the interference. After my own issues, I have not used anything else and not had any negative effects - in about 10 cameras, 3 of which had external DAB units, which were also independently powered by the same power supply.

Agreed. My 12v to 5v power supply caused my radio to drop out.

Update!
Thanks for all the suggestions. I fitted a roof mounted DAB aerial today and binned the window one. Can now receive all stations clearly and none of them 'drop out'. As for the dashcam interfering with the signal, the problem has gone, the strong reception has overcome the problem.
