Underground
Security
Expanded
The latest phase in London Underground’s
multi-million pound refurbishment programme
includes the installation of 60 Sony CCTV
cameras at three of South London's busiest
central stations: Brixton, Pimlico and Vauxhall.
Part of an integrated passenger security system, pictures from the cameras at all
three stations can be selected and received at a specially built control room at the
Brixton station where Sony S-VHS time-lapse VCRs are located, providing real-time
recording when necessary.
At Vauxhall and Pimlico, individual control rooms are also equipped with two
Sony recorders set in real-time mode, which receive pictures from their own
station cameras.
The SSC-DC50P CCD colour cameras are line-fed, simplifying installation by using
a single coaxial cable to send both video and sync signals. Chosen for their high
degree of resolution and identification capability, the cameras are located on
platforms, in passages and ticket halls as well as close to the new Help Points where
customers can communicate with London Underground staff (or with British
Transport Police).
As British Transport Police Public Affairs Manager, Simon Lubin explains, crime on
the Underground has reduced by 22 per cent since 1990 with one important
contributing factor being the installation of CCTV throughout the system.
“CCTV is a vital weapon in the police armoury helping to prevent and deter crime,
as well as to detect it. Our customer surveys show that CCTV also reassures people
travelling and is an important investment by London Underground in passenger and
staff security.
“Officers are using CCTV daily as a key investigative tool to trace and confirm
identities of suspects, as well as to obtain evidence for presentation in court. If it is
to perform those functions effectively, picture quality has to be as high as possible.”
The SSC-DC50P cameras use digital signal processing and Sony HyperHAD
technology to achieve high quality pictures in the most demanding circumstances.
