recently I have installed the latest version of Command Software version 3.1.100. I let you know that there was not any issue while doing the installation. Even all the three cameras were updated without having any issue. I noticed that everything was working without having any issue apart from Powerline diagnostic. Whenever I was running the same I got an error message for every single camera were not detected. As I am running camera bandwidth diagnostic I was able to get strength indicator for the every single camera. Let me know if you are having the same problem. also tell me if you know anything to troubleshoot the issue of mine. I am waiting for the prompt replies of yours.
