For everyone in this thread seeing error 90 and going offline, etc with the V3 Pan Cams, I have found them to be much more sensitive to long cable runs and voltage drop than other models, especially when Motion Tracking, Panning, and Continuous SD recording are used in combination and require the pull power draw (but especially with Motion Tracking on).
Those exact errors are often fixed with a shorter run and/or better power on the cable run. Here are a few threads that you might want to look at to see if that could be part of your problems (beyond the firmware fixes), and plenty of tips and suggestions. Hope this helps!
