The standard PoE switch distance limit is 100 meters, as defined by Ethernet transmission properties. In PoE (Power over Ethernet) technology, the Ethernet link between the Power Sourcing Equipment (PSE) and the Powered Device (PD) has a clearly defined maximum distance limit—100 meters (328 feet). This means that a PoE switch can reliably supply power to a compatible device up to this distance. When you use a midspan, you should calculate the distance between the camera and the switch that the midspan is connected to.
