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?
Serial comunication cables can reach 50 meters and to reach more than a hundred you need some ICs like a couple of max483. The real problem is with the web cam signal, I need to see what's happening in real time and to see it on a screen. Usb cable can't reach more than 5 meters... What happens If the cable is more than that? Is there any solution?
