I bought a network camera that supports PoE. Therefore, I wanted to buy a PoE switch. The connection was easy: the router, a cable into the switch (the ports without PoE) and then 3 ports without PoE and 4 remain with PoE. Each of the 4 PoE ports delivers up to 15 watts. For my camera (Axis) absolutely enough. In just a connected camera was the power consumption at 5 watts. The manual of the router speaks of 60 Watt .... I would naturally become nervous. However, the 60 Watt are simple 4x the maximum wattage of 15 watts.
When I turned on the fan in the camera, the power consumption is increased to 11 Watt. Everything in the frame. For me, just the right equipment and the price fits.
