You all should remember that IF you have ethernet ALREADY with POE you can draw power from it.
So if someone already put holes in your wall to run ethernet (or coax) and the cables are there you can buy
or run power over coax
BUT
If like many of us your house has not had holes drilled throughout it can be daunting to install a bunch of cameras. And what if you want to reconfigure?
Whereas I just installed 2 Pan cams and a V2 to watch a visiting dog in 4 rooms while we are away at Thanksgiving dinner. It probably took about 10 minutes (after I found the second pan cam power supply 
)
Wyze should start selling PoE-to-USB adapters to get power to the V2’s. Data would still go via WiFi.
