Is there anything else that I should think about if these would be my options? Any problems I might run into?
Agree with estore that the B1W will be much easier to position for the side mounting, it also has a significantly wider angle lens than a A119 V3, and for the side wider is better, and it will use very roughly half the power, so can use a powerbank half the cost.
The A119 V3 will have significantly better image quality, and I would happily recommend it for the front and rear, but it is unlikely to be necessary at the sides. The B1W does a pretty good job in the dark, the only big difference is the amount of motion blur when vehicles are moving, but that may not be an issue if you are parked and it is people rather than vehicles that you are worried about.
I don't know much about the Aukey DR-01, but I don't notice people recommending it, and the mount doesn't look a good design to me. It has the same image sensor as the B1W, and since I know the B1W does a very good job with that sensor, I doubt that the Aukey DR-01 would have better image quality.
The A119 V2 has a wider lens than the V3 and higher resolution than the B1W so from an image point of view it may be a good compromise, but for a side camera the B1W is definitely a better shape/mount, and if you are running several cameras 24/7 then the power consumption should be a consideration, for power the B1W wins.
Do consider the parking modes available, the A119 V3 comes with a selection in the menu, the B1W has several firmware choices, the choice may depend on what you want it to do.
