I have mine hardwired into power circuits that come on when the key is on. So my front cam is hardwired to the power feed for my auto-dimming mirror, and my rear cam is wired to the power feed for my rear wiper motor. I use small 12V-5V DCDC converters (These ones from Amazon) and just run the cable out from under the headliner to the cam!
​
Edit to add: You only need a power source in the rear if you use two separate cams like me. If you use a dual cam it gets its power from the front.
I'm going to try these: https://www.amazon.com/Converter-Regulator-Waterproof-Converters-Smartphone/dp/B07H7X37T6/ref=pd_lpo_vtph_23_tr_t_1?_encoding=UTF8&psc=1&refRID=C2MA8V46QEZDEB8XFHDR
I found a better way. First a 12v to 5v usb converter. Second a 12v Li-ion rechargable battery pack with charger. I have used the 12v pack and they work well. I did a similar 12v to usb, to power a video recorder.
