Ethernet cables can transmit video, audio, and power beyond basic internet connectivity. For long-distance video, HDMI extenders allow Cat5e or Cat6 cables to carry signals farther than standard HDMI, though this is not true Ethernet networking. Category cables can also carry multiple analog audio channels with adapters, useful in studios with existing wiring, though XLR cables remain simpler for most setups.
Power over Ethernet (PoE) enables a single cable to deliver both data and power to devices like security cameras and Wi-Fi access points, eliminating the need for nearby outlets. PoE requires compatible switches or injectors and equipment that supports sufficient power delivery. While category cables offer niche solutions for repurposed wiring, alternatives like active optical HDMI or standard audio/power cables are often preferable.
They are best viewed as a flexible option for specific installations rather than a universal replacement.
