Intersection Signal and Video Integrated Networking

Aggregate signals, detectors, and multi-camera video at the cabinet with LGS2000-8GE2GF-M VLAN/QoS.

1. Scenario

Signal controllers, detectors, and intersection cameras often share one cabinet and need traffic isolation with low control latency.

2. Challenges

Video bursts can starve control packets; mixed vendors need flexible GE ports; intersections need fiber rings.

3. Architecture

Deploy 8GE+2SFP managed switches in cabinets—copper for controllers/detectors/cameras, fiber for ring/uplink; use 8GE+4SFP where more fiber directions are required.

4. Recommended Leagrid LGS2000 products

LGS2000-8GE2GF-M: Managed Gigabit industrial switch: 8×GE copper + 2×GE SFP; VLAN/QoS/ring redundancy for intersection and shop-floor aggregation.
LGS2000-8GE4GF-M: Managed Gigabit switch: 8×GE copper + 4×GE SFP for multi-direction fiber rings and multi-camera uplinks.

5. Deployment notes

Prioritize signal traffic with QoS; VLAN-separate video vs control; validate ring convergence; keep an out-of-band management plan.
