Hi fenderman, 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?
