I would start with an open enclosure, like a bird house without a front panel (maybe also without a bottom panel, just so that the rain and sun doesn't hit it directly. You will need a long cat 5 network cable from the cam to the power injector, and then a shorter cat 5 cable from the power injector to the router (there may be a short one included, not sure). If you don't have the tools and expertise to make your own cable then buy a ready made one, 100' ones are pretty cheap on ebay. You'll have to think how to protect the cable, ideally run it in pvc conduit or water pipe.
