MikroTik CRS112-8P-4S-IN

CRS112-8P-4S-IN is a managed switch with eight gigabit PoE-out ports and four SFP. PoE on every copper port means cameras, access points and IP phones draw power over the same cable that carries their data — no sockets needed beside them.

The four SFP ports take the fiber: an uplink to the core or links to neighboring buildings. For a small site this is a complete node — switching, device power and a fiber exit in one box.

The unit runs both as a switch (SwOS) and as a full router with RouterOS: VLANs, firewall, DHCP, VPN. A 400 MHz CPU and 128 MB of memory are enough to route a small network without a second device.
