I had a 5216 4ks2 and now I have a NVR 5232-16p-EI. I know Andy's naming is a little different but that's close enough lol. My old one didnt have poe. I just used a poe switch but my switch only has a few ports left so this works out good. I also updated the firmware since I have to learn new features anyway. Figured I'd do it all at once lol. I upgraded to DH_NVR5XXX-EI_MultiLang_V5.000.0000000.0.R.250417 and its a completely different NVR now. It will take me a while to get used to where stuff is and the menus but overall it works well.
