This network-capable device is powered via Power over Ethernet (PoE) through 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 many cables would be disruptive. You save on installation costs and can enhance the reliability of connected devices by using a central uninterruptible power supply if desired.
