I figured out the problem. Basically, 2nd one of my PoE camera kept cutting in and out. It turns out that the rain storm also messed up this camera connection. I electrical taped a male rj45 to a female-to-female to a male rj45 cable. Well, over time, the electrical tape expanded open...allowing some rain to get in. The camera's intermittent operation was giving me a tell-tale sign. I was able to locate the problem quickly.
Lesson learned....... this camera almost burned out but i'm glad I caught it in time.
Now.... i'm contemplating just running straight bare upgraded outdoor rated cables with NO connection joints. I would protect all connection joints with a weather proof junction box.
