Phantom Power - not usually considered within the PoE / PoC 'family', but Phantom Power sends a 12-48 volt DC voltage along with the audio signal form an amplifier for use with condenser microphones. PoH (Power-over-HDBaseT) the latest Video-over-IP technology - HDBaseT - simultaneously transmits HD video, audio, control signals and power from device to device over Ethernet cable to distances of up to 100 metres. *(PoC also sometimes refers to Power-over-Coaxial cable) Power over Cable will apply power to the line directly without detecting a device at the remote/receiver end. Therefore, the voltage supply can be set to meet the needs of a specific product/system (which may be lower or higher than voltage range of PoE). PoC* ( Power-over-Cable) works to similar principles (supplying simultaneous power and data signals over Cat cable) but is non-standardised and is applied to proprietary systems. Power over Ethernet will only apply power to the line once a remote device / receiver has been detected on the line. This ensures that any PoE device connected to a system receives a compatible power supply. PoE is standardised to adhere to specific voltage ranges between 37 and 57 volts. PoE (Power-over-Ethernet) is an electrical industry standard which allows electrical power to be transmitted simultaneously with data signals over Cat5e/6/7 cable. What is the difference between Power-over-Ethernet (PoE) and Power-over-Cable (PoC)? However, a PoE enabled camera will receive both data and power over the same network cable from a network / PoE switch or from the system's NVR. Power-over-Ethernet (often referred to as PoE) is a technology which provides electrical power over standard Ethernet cables - in most cases providing the power delivery simultaneously with the data signals sent from one device to another.Īs an example, a CCTV camera would normally require both data cable and an external power supply - from two separate cables.
