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.

WELCOMEWELCOMEAt Dedicated Micros our reputation has been built on the

innovative nature of the CCTV systems we develop, their

reliability of operation and the comprehensive after sales

support we offer to customers. As a specialist manufacturer

for more than two decades, we’ve spent millions of

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.
