Is there a decent 1080P Camera that is wireless in terms of sending video signal, but can plug into AC Power and continuously feed a dedicated monitor? Sort of like the older CCTV camera setup, but using my LAN or WAN to send video to assumingly a website hub that I have a PC and monitor dedicated to?

I’d like to avoid running ethernet or CCTV wire to a camera, but have the perk of an active live feed from at least one, maybe two cameras in the house. I’d assume it will slow my network down some, so I would close the feed during high demand hours *of internet speed.
