I know there are plenty of threads on dash cams... But none seem to cover my idea:

The maplin one only has USB out, so you'd need to make sure you have a USB powered camera and not a 12v one.

The Blackvue will cut the dashcam off at say 12.5v which means you can at least start the car.

To provide an independent 12V supply for cameras you would be better using one of the many portable jump starter packs available. The packs are small enough to hide out of sight and could be charged from an ignition controlled circuit on the car or via an ignition controlled relay such that when the car ignition is off the pack would be capable of feeding the cameras without draining the car battery. A 12V supply could be taken from the pack using the booster cable outputs by removing the fitted crocodile clips and fitting an accessory socket in there place to allow the camera plug to be plugged in. |

a lot of these power jump start packs do have a ciggy socket built in , some also have a 5v usb socket... ... - .- -.

No - USB is about 5v so the easiest way would be to wire in a trailing cig socket and a USB adapter |

I only googled that one and price seems ok. I'm only at planning stage, haven't bought anything - wanted to get any thoughts. Consensus seems to be to get 12v power. The further you got up in capacity, the nearer you get to a full second car battery install. Probably overkill to run a couple of cameras though... If anyone has a go, please post anything. Even theory! . Cheers, Greg - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 2011 Vogue SE 4.4 with lots of toys in Stornaway |

Dual car batteries would require a higher spec of cabling and switching - a pack designed for cig lighter charging will have something regulating how much current it pulls, so much easier to install |
