2.5G Ethernet Switch

2.5G Ethernet Switches for 4K Cameras and NVR Uplinks

Once a project runs 4K cameras, multi-client playback and a 2.5G NVR, a gigabit uplink becomes the bottleneck before the switch does. These units give 2.5G copper ports plus 10G SFP uplinks, so one chassis carries the camera side and the recording side without a second aggregation layer.

When 2.5G actually helps

Not for a single stream — for concurrent load. Sixteen 4K cameras writing to the NVR while two operators pull playback is where 1G uplinks start dropping frames. Add the NVR's own 2.5G port and the case for 2.5G is clear; for eight 2MP cameras it is money spent on nothing.

Uplink and PoE versions

Match the SFP uplink to the fibre run (multi-mode to 550 m, single-mode beyond), and pick a PoE version when the cameras are powered from the switch rather than locally.

See RS1025K-4LG-2S-10G for the 4-port 2.5G model with 10G uplink, RS1025K-16LG-2S-10G where sixteen 2.5G ports are needed.
