Dahua ePoE Long Distance UTP / Coax Tested

By Ethan Ace, Published May 03, 2019, 10:03am EDT

Dahua's Enhanced PoE (ePoE) line is claiming extended video and power transmission over 600m without repeaters, with devices interchangeable via UTP or coax, a claim that few competitors make.

We bought and tested ePoE converters, cameras, and NVRs, including:

To examine these questions:

  • Does transmission distance meet Dahua's specs?
  • How does cable quality impact performance, using RG59, micro coax, and low grade connectors?
  • Is there any visible impact on image quality?
  • What configuration and setup are required?
