I have Pan-Cam V3’s running off 12 volt to 5 volt USB adapters that I run low voltage landscape wiring to.
You can daisy chain this setup for as many cameras as needed by choosing correct power supply to feed the adapters.
This adapter would work with a pan cam v3 as long as you seal the usb connection to the Wyze cable with good waterproof tape.
Below is a link to instructions posted before about this setup, just use above adapter instead of whats on link below
