Got a couple of extra 1st gen xCAM to add to my home security system a this past summer. Initially got them all to work and paired to my system. Went to install them last week and ran into issues with having to put new RJ45 connectors on after installing the wiring through the wall and figured out hte trick about adding the loop with from pin 4 to 7. Now it looks like my devices are turning on, but the system isn't seeing them and almost like I need to repair them. I remeber this took some time and had to do a factory pair between the 2 devices. Xfinity procedures are not working as they took the bridge router out last year. Do I need to go back and repair with the Y-adapter to get them talking. Right now all I have is the Power Supply blinking blue and the camera just has yellow lights, never goes blinking blue.
