Question about using IPC-Color4K-T for covert face detection

I would only use if you have a dedicated wifi AP that is just for the cameras and not part of your home wifi and internet.
 
Do these ip cameras work with Powerline Adapters. Location doesn’t allow me to run a CAT6 line directly to camera. I probably would have to use a PoE injector to make this work.
I'd say maybe to probably. Every house is wired differently though so there is no way to know until you do it.
