What is poe used for totk?

POE (power over Ethernet) is a technology that allows for the delivery of electrical power along with data over a single Ethernet cable. This means that devices such as cameras, phones, access points, and other network devices can be powered using PoE rather than requiring a separate power source.

PoE is commonly used in Internet of Things (IoT) applications, as well as in security and surveillance systems, where it allows for simplified installation and reduced costs. It is also used in industrial automation, telecommunications, and other applications that require powered network devices.

There are different standards of PoE, with the most common being IEEE 802.3af, 802.3at, and 802.3bt. These standards define the amount of power that can be delivered over the Ethernet cable, as well as the maximum distance over which the power can be transmitted.

Overall, PoE is a versatile and convenient technology that simplifies the deployment of network devices and reduces the need for multiple power sources.
