I finally picked up my NVR 5216-16P-4KS2 and single 2MP Starlight yesterday and was setting it up. The image quality is great. I'm a big noob at any networking other than following the install wizard for my router, but I paired it using the native software app and the P2P and it was as easy as scanning a barcode to get remote access.
I'm still working my way through the manual to get the settings right, but some of the menu options don't match up with the different firmwares making it a little tricky to follow along. I can at least remotely access the cameras and watch playback for now. Next up is learning how to set alarm notifications. I have it set up for 24/7 recording on two 3TB HDDs. Does anyone know how much I'll be able to record at 1080p for 5 cameras before it overwrites?
Thanks, ipcamtalk, nayr, and Andy for your help and recommendations. I definitely need to order more and wire my house soon to complete my setup once I get the settings tweaked with the one camera.
