COE have won a contract to provide a major security upgrade for Seoul's Metro network. The system provided will include capability to manage 8000+ cameras.

Project brief

Seoul’s Metropolitan Subway is the third most heavily used Metro system in the world, serving over 8 million journeys daily in, and around the capital of South Korea. To ensure secure operations for 8 million commuter journeys daily, maintaining an effective security presence is mission critical for the success of Seoul’s Metropolitan Subway network. COE has been selected to provide a major security upgrade for Lines 1, 3 & 4 of Seoul's Metro network. This upgrade integrates state of the art features such as intelligent video analysis technologies and PTZ auto-tracking to permit CCTV operators to maintain secure operations of the metro network for many years to come.

Analysis

COE’s rich history of providing highly reliable, fully redundant CCTV systems to some of the most prominent rail sites around the world was a key factor in the successful project bid for Seoul Metro. The experience the company brings in engineering best-fit hybrid network solutions and leveraging the benefits of both optical fibre and IP Ethernet transmission technologies was key to establishing the optimum solution for Seoul Metro and enabled a cost-effective, scalable and highly manageable system to be specified, integrating COE’s state of the art transmission and management equipment.

Key requirements for the operations management team of Seoul Metro included:

• Capability to maintain the operations and visibility of 8000 cameras across a single network.
• Technological assistance to enhance the function of the CCTV operators was desirable, as there is an exceptionally large number of cameras to be operational concurrently.
• Access to cameras from multiple stations across the network to be facilitated at multiple control rooms around the network.
• Continuous operation with no downtime or lost footage, which is key for mission critical environments such as metro networks. This meant eliminating potential network downtime was essential.

Solution

In total, equipment will be installed in 70 stations across three lines of Seoul Metro. Each station will have a camera capacity of between 64 and 128 cameras. The combined camera count brings the capacity of the network to well over 8000 cameras. COE’s unique network architecture solution will facilitate instant uncompressed video transmission from any of these cameras by optimising usage of the existing optical fibre. COE’s X-Net VI analytics platform will provide intelligent video analysis of the video stream from over 1000 cameras across the three lines of Seoul Metro, including features such as: automatic tracking of suspects' movements around the station by PTZ cameras, ticket barrier avoidance detection, unauthorised area access detection and more!

COE's solution optimises the use of existing optical fibre across Seoul Metro's network to allow a systematic upgrade integrating new features and a greatly increased camera count. Innovative use of technologies such as CWDM (Coarse Wave Division Multiplexing) and the feature set of COE's expansive X-Net range of products have combined to fully optimise the network.

Benefits

Key operational benefits met by COE:

• Heightening security across three lines of a very expansive and busy metro network.
• Integrated VI features - The range of intelligent video analytic technologies to be employed across the network will enhance the function and abilities of the CCTV operators to manage such a large network effectively.
• Optimisation of existing resource. - COE's fully redundant solution ensures minimal disruption to train services not only during the installation process, but also that the full redundancy ensures that the system is never compromised due to individual equipment failures.
