Got it. Thanks
@mat200. I have the NVR/camers on a router that's not connected to WAN. Plan to read/research on how to have the most effective configuration.
Looking around the internet, I found this one:
Hikvision Compatiable 8MP 4K H.265 Dome POE IP Camera 2.8mm Outdoor Security Cam - Newegg.com Looks a lot like the one I received. There is also someone selling the same type on eBay.
