Camera system and HA integration

Hello, i’m just getting started with HA and i’m not sure if this is possible. I am trying to view all cameras on HA. I have 11 amcrest cameras and a hikvision NVR. I’ve tried to follow Amcrest - Home Assistant for integration but after typing in the user name and password i’m lost on what to do next. Is there something I need to do with the NVR?

Thank you!

If the IP / username / password are correct, after a reboot your camera should be available as an camera entity.
