Unmanaged Mercusys PoE switch with (6) 10/100 Mbps of which ports 5 and 6 without PoE can serve as uplink and the remaining 4 ports support PoE out with 802.3af/at standard (up to 30W/port). The total PoE budget is 40W. 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. Other switches of the switch are PoE Auto Recovery ensuring automatic power restart for elements that stop communicating and Port isolation to determine end element communication only with the uplink port.
