I use IP cams that are on home LAN. I have NVR to control, record, playback....
At home I can watch with screen attached to NVR or android app.
My problem starts when I am out of home.
Network provider is changing IP on router daily.
Router has open DMZ port with NVR IP. When network provider change IP and I am not home I cannot remote to NVR.
Do You have any advice?
