I have a mixture of 10 cameras on a Blue Iris system, a i5-2500K - 8 GB mem and we had a city-wide power outage for 5 minutes. When the system came back up 4 of the cameras had lost their IP addresses and a couple of others came up but had the wrong cam ID .... they had switched. For instance: one that used to be "Sound System Camera" came up as "Parking Lot Camera". All cameras are hard wired and well within cable length tolerances and the cpu load is anywhere from 46% to 70%. I've thought about a UPS for the server but since I have several Switches in different locations throughout the installation that would not protect them ... but I'm not sure that would matter?? Or would installing a UPS be beneficial in saving the IP addresses? Or ... is there a way to lock down the addresses?
