Long IP Camera Run Options: Fiber, PoE Extenders and EoC Examined

Author: Ethan Ace, Published on Aug 09, 2011

A common question in IP surveillance is: What are the best ways to extend power and Ethernet past the typical 100 Meter limitation of UTP cable? Indeed, this is often cited as a weakness of IP relative to analog cameras. This is a controversial criticism for sure as IP has the powerful advantage of networking across large IP networks that can easily overcome even great distances. However, there are times when an IP camera is simply hundreds or thousands of meters away with nothing in between. For those occassions, this note helps you choose between Fiber, PoE extenders and Ethernet over Coax (EoC)
