This I know will work - just tried it today. Need to replace a Night Owl wired DVR system. Since power wiring is in place, just need to push 5V/1A per v2 (or v3) over the existing wiring:
5V/10A power supply → 4 (and/or 8) DC splitter → DC female to USB A female adapter → Wyze USB A male to microUSB cable → v2 (or v3) camera
Bill of Materials:
5V/10A power supply ~$20:

4 (and/or 8) DC splitter: used existing Night Owl splitter

v2 (or v3) camera: ~ $20:

The only real dependency is how long the power cable runs. Other than that, this setup should run for most configurations.

Good luck!
