This network-compatible device is powered by Power over Ethernet (PoE) via the LAN cable. The main advantage of PoE is that you do not need a power supply cable. This allows you to install Ethernet-connected devices even in hard-to-reach places or in areas where a lot of cables would get in the way. You save installation costs and can increase the reliability of the connected devices by using a centralised uninterruptible power supply if required.
