What is PoC (Power over Coax) for CCTV

Marco Albertini by Marco Albertini

In this article, we are going to explain the PoC (Power over Ethernet) technology, what it can do, and usage situations. This is a great solution, just connect a single cable to the camera and you are done.

Video, PTZ commands, and power sent over coaxial cable makes the installation faster and cheaper. This technology is not new but is not being used by most CCTV enthusiasts yet, some are unaware of its existence and others just don’t want to learn about new technologies and leave the traditional system behind.

What is PoC (Power over Coax) for CCTV

Firstly, what is PoC technology? PoC stands for Power Over Coax, meaning that the power for the camera is supplied by the DVR via coaxial video cable (RG59 or similar), which removes the requirement for separate cables and power supplies which would otherwise be needed to power your cameras.

PoC technology combines and transmits high-definition video signal, coaxial signal, and power over a coaxial cable. You could power a PoC-enabled camera with just one cable.

It sounds similar to an IP CCTV system, whereby one Ethernet cable would power a camera and transfer the video signal too, but the costs are a lot lower.

You will find the acronym PoC in different catalogs of high-resolution analog security cameras with HDTVI, HDCVI, and AHD technology.

In addition, the HD PoC analog solution supports UTC for remote set-up and configuration and enables control of the OSD menu and PTZ control via coaxial cable, enabling faster camera installation and easier management. All that’s required is for the cameras to connect to the back of one of their range of PoC-compatible DVRs.

Advantages of using Power over Coaxial in surveillance camera systems

  • Reduces both installation time and material costs.
  • Analog HD CCTV users can now enjoy 5MP to 8MP cameras and 4K video resolution while using their existing cabling infrastructure.
  • Power over Coax can greatly increase the length of cable over which you can run the camera. PoC extends this distance to up to 600 feet (200m).
  • PoC systems do not require the installation of power supplies, power cables, connectors, or sockets.
  • PoC systems are versatile and provide a new tool for installers or DIY enthusiasts looking to set up a hassle-free, plug-and-play CCTV system.

Manufacturers that support PoC technology

Hikvision, Dahua, Lilin, and Webgate are some of the manufacturers that provide technology to power CCTV cameras over coaxial cables.

As manufacturers are licensing the use of the technology to other companies, it is likely that you will find other brands distributing PoC-powered cameras. You can purchase PoC cameras with HDTVI, HDCVI, or AHD technologies, a few different manufacturers are already using this standard.
