OK thanks so much for taking time Jose. Unfortunately, I made one step forward and two steps back. From within the Dahua Config Tool I tried to set the camera gateway to the same as my router (192.168.1.1) however it would not permit that. So I decided to go back to square one. I performed a hard reset on the camera to set it back to the Dahua default which is IP 192.168.1.108, username: admin, password: admin. To see if that worked I went directly to 192.168.1.108 and a login screen came up which demanded that the password be changed. So I changed it to xxxx123. However, the live image was not visible from that page.
So, I went back to the Config Tool and it could indeed see the camera with the updated IP 192.168.1.108. From within the Config Tool there is a web login button for the camera, and when I clicked that it takes me to a login screen. I entered the new password and then I could see the live image. Next, I removed the camera from the main network switch and plugged it into the NVR POE port. In the NVR, in "manual" mode, I modified the camera to IP 192.168.1.108, ONVIF, and the updated password xxxx123. However, the NVR came with the error "Network is unreachable".
I have tried so many different things I thought I would stop right there so that you can see exactly where I am at. What steps would you recommend next? Again, really appreciate your help.
