Global and U.S. Ethernet-over-Coax Extenders Market Report, Published by QY Research.

A large retail chain in the United Kingdom struggled during its digital surveillance upgrade when attempting to replace decades-old analog CCTV systems with modern IP cameras. The existing infrastructure consisted entirely of long-distance coaxial cable runs hidden inside walls, ceilings, and conduit pathways that were expensive and disruptive to replace. Traditional Ethernet cabling could not be pulled through many of the constrained pathways, and early PoE injectors failed to provide stable power delivery over long distances. As a result, the company faced escalating installation costs, long downtime windows, and unreliable camera performance.

To solve the issue, the integrator deployed Ethernet-over-Coax (EoC) Extenders, which convert standard Ethernet data and Power-over-Ethernet (PoE/PoE+) into modulated signals suitable for transmission over legacy coaxial cables. These extenders feature high-voltage PoE passthrough, long-reach PHY chipsets, adaptive modulation, and built-in surge protection to support distances up to 1,000+ meters. After installation, the retailer preserved its entire coax infrastructure, achieved stable gigabit uplink performance, and powered high-resolution IP cameras without any rewiring. Deployment time dropped by 60%, overall cost-of-upgrade fell by 45%, and the system gained improved reliability during peak operating hours. EoC extenders are now widely used in security retrofits, industrial sites, hospitality networks, parking structures, and any facility upgrading from analog to IP without infrastructure replacement.
