But how do I go from web cam to ethernet? I found this on amazon http://www.amazon.com/SANOXY-over-Extension-Cable-Adapter/dp/B003BDMK3S/ref=sr_1_1?s=electronics&ie=UTF8&qid=1344427592&sr=1-1&keywords=ethernet+webcam, can I use someting like that? What if I use a 300 ft ( nearly 100 meters) CAT 5 cable instead of only 150 ft?
