Ethernet Surge Protector | Protect PoE Camera Again Lightning Caused Surges | cat5 Surge Protectors

I installed 4 of these then realized all of my cameras were down. Started removing them to find they were all smoked. We have a standard PoE camera system. Nothing unusual. I installed the protectors following the instructions that came with them. After I checked to make sure the cameras were back in operation, I tried to install just one and that camera came up for about 30 seconds and went down. Protector was smoked. I checked for stray voltage and everything was normal. Due to scheduling conflicts I wasn't able to install for 30 days, so I can't send the remaining ones back for refund through Amazon. I would still like to return the remaining protectors.
