I currently do not have a surge protector on it. I’m looking into using a small UPS battery/surge protector for it.
I’ve had this setup since February. No issues so far. I imagine there can be soo many factors as to why that happened for that person. Hopefully that doesn’t happen to me but, if it does I will surely report it on here.
Post in which all cameras were fried. He/she used same POE injector as Nesto with very similar splitters. Surge protector sounds like a great idea.
