The nvr does have built in poe so I literary just plugged them in and ran with it. My nvr ip address is 192.168.0.11 (which I can login to through the web browser), but my cameras are all 192.168.254.2 (the last digit goes up to 3,4,5 and so on through my cameras...) and all of the camera ip addresses do not take me to the login when I type it into the browser and I don't know why?
PoE NVRs usually create an separate, isolated sub-network dedicated to the cameras. In your case, it looks like that subnet is 192.168.
254.x
It looks like the regular subnet in your house is 192.168.
0.x... this is the one your NVR, computers, router, and other devices are using. Generally speaking, devices on this subnet aren't going to be able to directly connect to devices on the
other (camera) subnet, and vice-versa.
Try plugging your computer's ethernet cable into a port on the NVR. That should give your computer an IP address on the camera subnet (192.168.254.x). Once your computer is on the camera subnet, you should be able to use the web browser to connect to the cameras.
Newer Dahua NVR firmware lets you connect to the NVR using a web-browser, and then it can also jump you over directly to the cameras (to avoid the hassle of having to physically plug your computer into the back of the PoE NVR). I'm not sure if Hikvision NVRs have this feature too... it would make things easier for you if you have do this often.
