This switch an split one ethernet cable to up to four gigabit ethernet ports with 30W power over Ethernet. It has L2 slave VLAN. Comes with power cable (not pictured). It's perfect for a 10-inch mini rack like the Lab Rax 3D printable mini rack. It was only used briefly.
If you need more ports I have a 10-port PoE+ switch for $30; again, only used briefly.
I have one Reolink RLC-812A 4K security camera with visible daylight LED light on it for $45.
I can set your cameras up for you for $25 per hour. I also have some 4K Reolink RLC-810 PoE security cameras for $50 each.
