I replied to your DCS-2310L post first, but actually, you might be able to do what you want with the DCS-2332L. There is such a thing as a POE splitter, you could use one to supply power to the DCS-2332L's regular power connector (but if the camera is truly outdoors and exposed to the weather, you should try to figure out how to keep all the connections dry). Here's one:

Or you could try to cob together connectors to run 5V through the ethernet cable directly (preferably using 4 of the wires for positive, and 4 for negative, to minimize voltage drop), but because you're trying to send 5V over a long distance over light gauge wire, it might not work well (as well as POE, which runs as high as about 50V over ethernet; then the POE splitter steps it down).
