Reusing Existing Twisted Pair Cabling

Author: Ethan Ace, Published on Feb 20, 2012

Reusing analog camera cabling is a common topic in the surveillance industry, as recabling is a significant expense and disruption. This discussion normally centers on Ethernet over coax (EoC), however, as the vast majority of analog cameras are installed using coax. A similar technology exists for cameras installed on UTP, allowing these cables to be reused for IP cameras, which can also allow in-place telephone cables to be used for backhaul. In this update we will examine the basics of Ethernet over twisted pair, its most common applications, and manufacturer options.
