What is PoC (Power over Coaxial)?

Power over Coaxial (PoC) is a technology that allows both power and data to be transmitted simultaneously over a single coaxial cable. This eliminates the need for separate power and data cables, simplifying installation and reducing costs.

PoC works by injecting a DC power signal along with the data signal over the same coaxial cable. Specialised devices, such as PoC transmitters and receivers, are used to manage the combined signals without interference.

Simplified Installation: Reduces the need for multiple cables.

Cost-Effective: Lowers material and labour costs.

Improved Efficiency: Minimises clutter and maintenance requirements.

Long-Distance Transmission: Supports power and data transfer over extended distances.

PoC is widely used in surveillance systems, such as CCTV cameras, where it simplifies wiring. It is also employed in industrial automation, transportation, and telecommunication applications.

Yes, PoC can often be implemented using existing coaxial cabling, making it an excellent choice for upgrading older systems without significant rewiring.

Devices such as IP cameras, monitors, network switches, and industrial control equipment can support PoC when paired with compatible transmitters and receivers.

While PoC is highly efficient, it may have limitations in power delivery for high-consumption devices and could face distance restrictions depending on the cable quality and installation environment.

PoC transmits power and data over coaxial cables, whereas PoE uses Ethernet cables. PoC is preferred in environments where coaxial infrastructure already exists or where long-distance transmission is needed.

Consider the power requirements of your devices, cable quality, distance of transmission, and compatibility with existing infrastructure to ensure optimal performance.

Yes, PoC is designed with safety protocols to prevent overvoltage, short circuits, and interference, ensuring reliable and secure power and data transmission.
