Security at Transports Metropolitans de Barcelona
2,700 Sony Cameras Help to Watch Over Passengers’ Safety
Public transit operator Transports Metropolitans de Barcelona (TMB) runs one of Europe’s most technologically advanced and accessible metro system that comprises nine lines and 150 stations. TMB’s metro and local bus lines carry over 550 million citizens, commuters and travellers annually across the Catalan capital and surrounding areas, making safety and operational efficiency high priority topics.
In recent years, TMB elected to update its analogue infrastructure, replacing older cameras and extending coverage to create a metro-wide IP video surveillance system. The relationship between TMB and Sony dates back more than fifteen years, when the operator installed its first 150 Sony cameras at several metropolitan bus depots to protect perimeters, parking areas, workshops and office spaces. The proven reliability of Sony cameras has made them an optimal choice for the recent upgrade to monitor train tracks, station platforms and other public areas where reliable 24/7 performance is essential. As well as round-the-clock reliability, Sony cameras provide excellent HD image resolution, which was another key requirement for the project. Support for open protocols, including the widely used ONVIF standard, simplifies integration with other security and monitoring systems.
Simplified Maintainance and Lower Operating Costs
By standardizing on a small number of camera models, TMB has further benefited from simplified maintenance and reduced operating costs. To date, TMB has installed a total of 2,700 Sony IP network cameras across its transportation network with more than 700 of them being Sony SNC-EB630 box-type models. A custom housing protects the cameras from dust, dirt and physical tampering while allowing easy cleaning of the front lens window. The SNC-EB630 offers excellent Full HD image quality with wide dynamic range, even in dim or harshly-lit environments where other cameras often struggle to see clearly. Built-in image stabilisation assures crisp images, even when the camera is being shaken by mechanical vibration from nearby trains.
The SNC-EB630 also scores in station areas where harsh fluorescent lighting can be strongly reflected by platform surfaces, making identification of people and objects difficult.
Here, Sony’s View-DR technology boosts the cameras’ dynamic range to accommodate a wide range of light levels in the same scene. The cameras’ widespread presence serves as an effective visual deterrent, and as a useful tool to clearly identify and resolve incidents involving passengers and staff. What’s more, picture quality and sensitivity are major assets when monitoring the movement of passengers in congested station areas, or directing station staff and first-responders to help passengers requiring assistance in the event of accidents or personal injury.
Fully Centralized System
“Apart from superb picture quality, a key factor for us in choosing Sony cameras is their dependability” says Victor Ribera, Responsible of Telecommunication Systems in the Technology Area at Transports Metropolitans de Barcelona: „Remote surveillance is extremely important for us. We have evolved from a complete decentralized surveillance system started at our garages and workshops to a fully centralized system – based on security control centers for the operation and management of all security cameras. Image quality has improved exponentially in a short time. Together with the functions incorporated into the cameras themselves, this has resulted in an increase in the security offered to our passengers.”
