Because this is quite a long tunnel at under sea level, the owner requested a highly redundant system with a very high detection rate, high reliability (MTBF) and a very high level of service (% Uptime). This was one of the reasons why the detection cameras were installed at 60 metres distance, but programmed to cover at least 120 m. Case 2: ORESUND - Situation

THE Reference in Traffic Video Detection Basic Advantages of Video Based Incident Detection: Fast incident detection rate Visual verification High system reliability Easy to install and modify Low false detection rate & cost Low overall lifetime cost Summary

THE Reference in Traffic Video Detection Video detection works reliable. Video detection is the fastest way to detect. Video detection has the lowest false alarms rate. Video detection offers immediate verification via CCTV. AID, Automatic Incident detection is the best detection method for Incident management Conclusions
