Thanks for your great help so far! I have my cameras and NVR installed and running. The image quality is fantastic! I am trying to get the iDMSS app to work and it is failing to connect. After doing some reading, it looks like my IP addresses are off. My iMac has the IP address of 192.168.1.10 but my camera system and cameras are all at 10.15.6.141 (system) 10/1/1/65, 10.1.1.66, (cameras) etc... How can I change the system and camera IP addresses to the same 192.xxx.x.xx as my iMac and network in order to get the mobile app to work? Any suggestions would be greatly appreciated. Thanks!
