Ethernet cables are more than just internet connectors; they can transmit power, video, and audio across various setups. While primarily used for networking, these category cables find secondary uses in home theater and audio systems. For long-distance video, standard HDMI cables have limitations.
Ethernet cables can carry video signals over longer distances when paired with HDMI extenders, which use the cable as a connection between a transmitter and receiver. This is ideal for running video to distant projectors, though active optical HDMI may offer better performance for high refresh rates. In audio applications, category cables can carry multiple channels of analog audio with the right adapters, serving as a clever alternative to numerous individual cable runs, though standard XLR remains easier for most setups.
Most significantly, Power over Ethernet (PoE) allows a single cable to carry both data and power. This is a truly useful standard for devices like security cameras and Wi-Fi access points, eliminating the need for separate power outlets. However, equipment must support PoE and provide sufficient power.
Despite these capabilities, category cables are niche options rather than go-to solutions compared to dedicated HDMI or XLR cables.
