I have the A119, recording 1 minute videos in a loop. Having a small capacitor, the dash cam switches off almost instantly after disconnecting from the power supply.
What I'd like to achieve is to keep the cam working for at least one minute after disconnecting from the main power supply (hard wired in a car) so that it finishes recording the 1 minute video in case of an accident during which the electrical power gets cut off. Ideally more minutes, let's say five, to capture what's going on after the accident as well.
What I've found so far is this - simply using additional capacitors added between the main power and the cam:

Does it make sense? Is it safe?
I'm trying to avoid the use of the lithium based power banks due to the fire hazard.
