I see many questions regarding cameras stuck on 4.36.9.139. The reason some are stuck on 4.36.9.139 is because we released 4.36.10.2700, this firmware was replaced by 4.36.10.2864 which was halted due to an event recording issue. 4.36.10.3406 is to fix the event recording issue with 4.36.10.2864 and was only released to cameras that were already on 4.36.10.x.
