When it comes for risk management and security, flaws are inadmissible. Therefore, developing security policies and procedures to contribute to significantly reducing the number of threats and incidents is a priority.
Even in developing countries, the impact of implementing video solutions in underground stations is huge, as more and more people become aware of their role in preventing incidents.
Under the circumstances, the security provided by specialized staff in underground stations does not manage to cover everything from fast access, supply and maintenance of the information collected by access systems, alarms and video solutions. Currently, the best video solutions should make available a platform providing sophisticated and integrated solutions capable of automatically identifying “suspicious elements” at station access. Once these elements are detected, the warning alert delivers essential information to the nearest centre which takes immediate measures.
The recent incidents at underground stations (such as that in Minks in April 2011, when 10 people where killed and more than 100 injured) determined the approval and implementation of projects consisting in the development of video survey systems that can supply important information, stimulating critical infrastructure protection and maintaining command and control while specialized staff intervenes.
Becoming aware of the real situation makes the access to the information delivered by alarm systems, access control sensors and another survey systems of the perimeter absolutely necessary. By relating the information to video survey systems, security systems such as door block, access block, lifting barrier, video cameras solutions or changing recording rates and quality level can be automatically activated.
A series of problems arises with the implementation of these systems. All systems have to assure uninterrupted operation. For example, these systems have to benefit from energy resources, in case of blackouts, or protection against fire, as they record and store images based on sensors, while temperature sensors react only at a specific temperature.
Consequently, the recording quality is a defining characteristic of video solutions. “To contribute in the identification process and help with the progress of investigations, surveillance cameras have to provide high-quality images. When errors occur, they demand immediate correction, as the quality of recorded images has to be high enough to permit specific identifications”, declared during a conference on security, Chief Inspector Mike Neville, head of Scotland Yard’s Visual Images, Identifications and Detections Office.
