Hikvision HDTVI Power Over Coax Tested

By Ethan Ace, Published Feb 05, 2019, 10:50am EST

After years of delay, Hikvision's Power Over Coax (PoC) HDTVI models are finally shipping, aiming to make HD analog installs as simple as PoE, with only one cable required. But with IP camera prices dropping over the past few years, and new generations of cameras available, can TVI stand up against IP?

We bought and tested PoC camera and DVR models, looking at these questions:

  • How does PoC work? Is it plug and play?
  • Does cable length or quality affect PoC?
  • Does PoC affect image quality? How does it compare to non-PoC cameras?
  • How do PoC cameras compare to IP models?

See our results inside.

Models included in this test:
