TRANSPORT
SECURITY ON THE MOVE
Multi-camera digital video recorders,
such as our sophisticated TransVu,
are becoming a vital element of
transportation security, with
considerable interest already having
been generated for public transport
applications – whether it is school
buses in the US or Dutch commuter
trains. This is not surprising given the
potential of this technology to
address the vulnerability of what can
be an extensive infrastructure,
helping operators to spot unusual
activity and tackle the day-to-day
headaches of vandalism and assaults
on passengers and staff.
Looking at railways in particular, with
passenger numbers continuing to
grow across Europe - in the UK alone
during 2004 according to ATOC
(Association of Train Operating
Companies) there were a million
additional passenger rail journeys
every week - CCTV solutions need to
have the flexibility built-in to keep
pace with this rapid growth. One approach which
has generated considerable interest in a number
of countries - including UK, Netherlands, Germany
and Spain - is the application of multi-camera
digital recorders, such as our own TransVu.
When fitted to trains for example these compact,
self-contained, systems are capable of
continuously monitoring the inside of carriages.
There is even the potential to conduct remote
surveillance, from trains on key routes, so
complementing the existing permanently
positioned CCTV infrastructure. Applied as an
overt measure, with the cameras in public view,
experience suggests that this provides a
significant deterrent to criminal damage,
delivering much needed reassurance to the
travelling public. In some cases, to enhance
protection for staff and passengers, digital
recorders are linked to a panic button. In the event
of an emergency, the panic button is activated by
authorised personnel, such as drivers or train
managers, so initiating an immediate call to a
control station for assistance.

In operation TransVu is capable of
multiplexing and recording up to 8
cameras, whilst multi-channel audio
recording can be used to store
relevant voice information and the
associated images from multiple
points in a bus or train - especially
useful in incidents of staff or
passenger abuse. Storage is usually
via one or two internal hard disk
drives, although some operators may
prefer a single removable drive which
can be taken from a unit in the event
of an incident.
As TransVu is a digital system
different record rates can be applied
to specific cameras, this ‘variable rate’
recording means that cameras can be
prioritised in the recording sequence.
Alarm inputs or system events can be
used to trigger changes in the
recording speed, making it possible to
record incidents at a much faster rate
than normal. TransVu also comes with
an advanced go-to-time feature,
>> THE CHALLENGE
The largest rail operator in the
Netherlands, carrying more than one
million passengers every day, was
keen to enhance the security
measures at its disposal to provide the
safest possible environment for its
staff and passengers. In particular,
the operator wanted to be able deal
more readily with aggressive
behaviour – a key concern for those
travelling on its trains, reduce the
level of vandalism and, crucially,
facilitate the detention and ultimate
conviction of the perpetrators.
>> THE SOLUTION
The solution was to turn to Dedicated
Micros and TransVu a digital video
recorder - specifically designed for
transport applications - to conduct a
mobile CCTV surveillance trial,
continuously monitoring the inside of
carriages. Initially TransVu units were
installed in 8 Sprinter type trains on
the busy City Line, each featuring 14
cameras and 2 recorders.
Results from the initial trial of the
TransVu system were extremely
positive finding that 60% of commuter
train passengers felt safer with digital
recorders and cameras installed. Train
staff also believed that their working
environment (and that for the
travelling public) had improved and
urged the CCTV surveillance to be
expanded to all trains on the City Line.
The bottom-line figures were
impressive with damage due to
vandalism plummeting by 45% from
140,000 to 80,000 Euro. During the
test period video recordings were
reviewed on several occasions,
assisting the police and the train
operator to solve a number of incidents.
The advantages of the TransVu system
were also brought into focus when the
trial ended, helping the authorities to
apprehend arsonists - who had set fire
to a train at the main railway station -
as a result of the quality of images
collected from cameras on a City Line
train. Significantly, the success of the
trial has lead to the expansion of the
TransVu solution to every double train
on the Dutch route – 18 in total –
providing the operator with a powerful
security tool to tackle the day-to-day
headaches of vandalism and assaults
on passengers and staff.
Future enhancements of the TransVu
solution are likely to include the use
of broadband spectrum transceivers
to supply real-time information on a
train’s operational environment back
to a control station.
supporting playback from a specified
time and date to tie-in with particular
incidents. It is also facilitates visual
searches of camera images at up to
x1000 normal speed and even closer
inspection at one quarter speed (slow
motion) to allow for the rapid location
and detailed study of incidents.
>> VEHICLE TRACKINGThe ability to process GPS (Global
Positioning System) information is
invaluable to track the position of a
vehicle from a security standpoint and
also as a powerful management tool.
Using GPS software mapping software
as on TransVu, the system can report
if a vehicle actually deviates from a
given track by a specified amount. If it
is off course, then the
system will automatically
phone-up the depot, send
an SMS text or even
pictures to alert the
operator that something
untoward may have
occurred. Where a
wireless LAN is available
e.g. airport applications,
systems can even
communicate without the need to
utilise cellular technology. Panic
alarm input can also be configured to
send images and personal data to a
control room.

>> POWER MANAGEMENTAuto power management is certainly
becoming a more common feature in
multi-camera digital recorders. In the
case of TransVu this stops a unit
recording and closes down operation
15 minutes after a vehicle is taken out
of service - a time period which can
also be defined by the user. The unit
will also conduct a controlled and
timed power down sequence when the
vehicle’s voltage has fallen below a set
level is. Once the minimum operating
voltage is reached this is immediate.
With a pass through relay controlled
power feature, during normal
operation, voltage is supplied (the
same as the input) to peripheral
devices such as cameras. This is
removed when the digital recorder
itself is powered down.
As TransVu is a digitalsystem different recordrates can be applied tospecific cameras
>> THE ANSWER IS EVIDENTIALAll individual images stored by the
TransVu digital recorder - which can
be archived to PC or mass storage
devices – carry vital header
information including date and time
and details of any alarms. With the
potential for images to end up in court
as evidence, systems need to be
designed to deliver a verified audit
trail. TransVu supports watermarking
where a unique finger print is
assigned to a range of images. As a
result, when evidence is submitted to
the police - for example on CD – the
watermark data can be issued as a
watermark certificate. To verify the
authenticity of the CD at a later stage
a second certificate can be created
from the images on the CD. If the two
certificates match then the CD has not
been tampered with. In some cases
evidence provided by such units may
even be able to assist train operators
by providing vital protection against
fraudulent attack/injury claims.
>> BEYOND SECURITYMore and more is expected of
today’s transport CCTV
solutions often being called
upon to provide information
which goes way beyond
security. The latest TransVu
system when installed on
buses with a sophisticated G
sensor is a case in point. By
detecting the forces which are
on a bus as it travels, and feeding this
back into the mobile CCTV unit,
including acceleration, deceleration
and cornering, bus operators can link
this information to specific events
caught on camera. Bus companies can
be vulnerable to costly and potentially
false claims. Anything which can help
them to ascertain the validity of a
claim and defend against
unscrupulous individuals has to be
welcomed - was the bus driver really
braking heavily when the incident
occurred?
>> MPEG-4In another industry first, the TransVu
now records evidential quality JPEG
images on the local hard drive, whilst
simultaneously making available
multiple connections of live MPEG-4
format, optimised for bandwidth
constrained networks such as a
wireless LAN. MPEG-4 video can be
streamed to a PDA for remote viewing.
This unique technology ensures that
users who are worried about
overburdening their network have the
opportunity to view video in real time,
without compromising recorded
picture quality. Fully flexible, the user
can independently configure the
TransVu’s transmission image
resolution, bit rate, and picture
update rate.
