In conventional analog systems, electrical engineers are required to install electrical wiring before cameras can be installed, which requires a lot of time and effort. Electrical sockets, ground wires, and separate power lines all add up to a considerable part of a system’s budget.

In 2017, Hikvision introduced Turbo HD 4.0 DVR series, which vastly improved on previous Turbo HD products. The Power-over-Coax (PoC) is the biggest new feature in TurboHD 4.0 products. Hikvision PoC technology features long transmission distance and reduces time and costs. In this article, the theory of PoC, as well as its application will be explained.

What is PoC?

What is POC CCTV technology? POC stands for Power Over Coax, which from the name allows a single coaxial cable to transmit both power and video signal between PoC cameras and PoC DVR, as traditionally analog systems one cable transmit power to the camera and another transmit video back to recording units.

This makes installation simple and easy which is great news for installers. Power over Coaxial (PoC) basically means that power is supplied by DVR via coaxial video cable (RG59 or similar) to the camera, which removes a separate cable requirement to supply power. For CCTV installers this means a much more cost and time efficient installation. PoC can be used up to 200 metres on cable runs and its POC DVRs are available in 4,8 and 16 channel DVRs, a full complement of Turbo HD PoC cameras are also available (models ending E) which together offer a cost effective and time saving solution to your TVI installations.

What is the difference between PoC vs PoE?

PoC stands for Power Over Coax, Hikvision introduced technology based on coaxial video,coaxial control and power superposition. POC technology realizes transmitting video signal,control signal and power in one coaxial cable.

POE stands for Power Over Ethernet, it's a common transmission way for IP system.We wrote many articles about POE transmission before,welcome read below articles to know more about POE.
