Reliable and accurate video surveillance is of utmost importance at critical infrastructure such as tunnels, bridges and highway crossings. With our client Rijkswaterstaat, we were able to implement VDG SENSE VMS in the 2nd Coentunnel which connects the main freeways of the northern part of The Netherlands with the country’s capital, Amsterdam.
Over 30,000 vehicles pass through the tunnel each day, and it required a video management system that was both powerful and had the possibility to interact with the many other safety systems implemented, such as fire & smoke detection, traffic flow control systems, intercom and variable message sign systems.
VMS offers powerful and intelligent features with a unique flexibility to integrate in any kind of security environment also offering critical features such as ‘failover’ which ensures that even if a system fails, video streams and recording can continue uninterrupted.
The VMS for Coentunnel is connected to the SCADA system through the OPC protocol. In case of alarms from other systems and sensors in the tunnel, events are sent to the VMS. It will then respond by controlling the relevant cameras and showing the corresponding video streams on the video wall and on operator screens.
