Enhancing Tunnel Safety with a Redundant Industrial Network in Malaga, Spain

What does it take to keep tunnel surveillance online at all times? A high-availability network built for mission-critical operations.

Ensuring safety inside road tunnels requires more than surveillance devices—it demands a highly reliable network capable of operating continuously under extreme conditions. In Malaga, Spain, a tunnel infrastructure project required a robust IP network to support lighting systems, IP cameras, digital signage, and VoIP communication, all connected to a remote control center.


Tunnel environments present unique challenges, including high temperatures, vibration, humidity, and the need for uninterrupted operation year-round. Any network failure could compromise visibility, communication, and emergency response.


To address these demands, Volktek INS-8528 managed industrial Ethernet switches were deployed as the backbone of the system. Designed for harsh environments, the switches support multi-rate copper ports for diverse devices and fiber SFP uplinks to enable long-distance transmission and a redundant ring topology with rapid network recovery. Redundant power inputs and an integrated alarm system further ensure continuous operation during power disruptions.


Today, the tunnel network operates reliably with high availability, fast recovery, and scalable expansion, providing a resilient foundation for safety and surveillance in critical transportation infrastructure.
