Upgrade SAV’s video surveillance system along the A5
Siqura’s managed switches
Digging tunnels under the Alps is not the easiest job in the world. Nor is managing them. EU safety measures only came about after a series of unprecedented tunnel disasters around the turn of the century. Today, standards across Europe are very high indeed and tunnel safety has improved dramatically thanks to various technological advancements.
As part of an ongoing safety improvement program, Italian motorway management company SAV decided to upgrade its existing video surveillance system via Project Automation. SAV’s primary requirement was to realise a peripheral network ring capable of collecting all IP security and CCTV streams inside the tunnels and along the motorway administered by the company (the A5 from Quincinetto to Aosta-West). Support for VLANs and the Rapid Spanning Tree Protocol (RSTP) was another key feature that SAV was looking for. The network equipment also needed to be environmentally hardened.
Together with Project Automation and Sinelec, two trusted integration partners, Siqura chose to implement several XSNet C4108SW rail-mount switches in the tunnels between Quincinetto and Aosta-West. These managed switches with integrated SFP slots are capable of operating in emperatures ranging from -40 ºC to +75 ºC. The control rooms along the motorway were fitted with XSNet S4124SW 24-port rack-mount switches with four Gbit combo ports. This setup provides logical isolation by VLAN and extra reliability through RSTP-based redundancy, while allowing SAV to connect its peripheral network ring to the WAN backbone.
