I removed the two cameras that I needed to change and the new ones booted up correctly and are working fine. I then tried to change the old cameras to the ip address of the unused channels on the NVR. After making changes on the SDAP software, I tried to add the cameras to the NVR. I can't get the cameras to activate. I get the Network abnormal message. It would be real nice to have a guide as to how to add and activate the cameras. I have mounted the cameras at a remote storage building using Ubiquiti bridge. I have a swich at the remote building for network access and will be adding a wireless access point. I also have a small POE 4 channel switch for cameras.
