Power over Ethernet is fantastic if you need to “bury” a switch in a wall, attic or Crawlspace. (Note that devices should always be “accessible”: but that doesn’t mean we can’t “hide” them). More devices are having PoE capability built into them all of the time. Even if they don’t come shipped with POE capabilities,… Continue reading Power over Ethernet for Devices
Category: Power over Ethernet (POE)
Power over Ethernet (PoE) is a technology that enables electrical power to be transmitted along with data over standard Ethernet cables. It simplifies the installation and deployment of devices like IP cameras, wireless access points, and other network-connected devices by eliminating the need for separate power cables. PoE utilizes unused wires in the Ethernet cable to carry low-voltage direct current (DC) power to the device, alongside the regular data signals. This integration of power and data in a single cable streamlines setup, reduces cable clutter, and provides a convenient and cost-effective solution for powering network devices, especially in locations where electrical outlets might be scarce or difficult to access. PoE is governed by standards like IEEE 802.3af, 802.3at, and 802.3bt, which specify the power levels and compatibility for different PoE devices.
