Unmanaged PoE switch from TP-Link with (5) 10/100 Mbps of which the 5th port without PoE can serve as an uplink and the remaining 4 ports support PoE out with 802.3af standard (up to 15.4W/port). The total PoE budget is 41W. The switch also enables PoE at a distance of 250m when switching a special switch, which causes the line speed on the PoE ports to drop to 10 Mbps, which is more than enough for image transmission from cameras. Another bonus of the switch is the switch for PoE Auto Recovery ensuring automatic power restart for elements that stop communicating.
