For the front, I use a Dongar adapter so it takes voltage from the mirror so it's only on when the car is on. For the rear, I use the 12V outlet which is powered when the car is on.
Let's troubleshoot it. Plug it to a regular USB instead of the Dongar. Use the one that came with the dashcam. Does it record and stay on continuously?
Lazy way to power rear dashcam:
Flat USB-C cable, get the connector your dashcam has:

Slim 12V adapter:

Yes. My guess is there is something wrong with the dashcam. Try updating the firmware first. Make sure you select the correct model. I think the A119 started to have voice on the A119 Mini or Mini 2. I have A119, A119S, A119v3, A119 Mini 2. Lol.
