Full Specifications
The EYR-PS4P1R1S is a 4-port Gigabit PoE Ethernet switch designed for powering and connecting IP cameras, wireless access points and other PoE network devices. It provides four PoE ports, one Gigabit RJ45 uplink and one 1.25 Gbps SFP fibre uplink, with 12 Gbps non-blocking switching so every port runs at full speed at once. A total PoE budget of 65W makes it well suited to reliable surveillance and network installations.
