Anyone know how I can create a setup where a dash cam (A119) can be powered from two sources - the main car battery when the engine is running, and when it is not running from a separate source (either a second lead acid battery or power bank)? I want the system to be automatic, as I'd forget to flick a switch and I don't want to drain my main car battery at all when the car's engine is off.
