Our client is one of the UK’s leading fast electronic ticketing system provider supplying most major rail / hotel / airline operators with their ticketing systems. Cash receiving ticket machines are easy targets for criminals wanting to steal money from them.

| As a part of a program to prevent criminals from vandalizing machines and stealing cash a strategy had to be devised to provide an early warning vandalism alert system. DC was asked to devise a mechanism to detect and alert central systems that a particular ticket machine was under attack. However the system had to be programmable to ensure that is was not falsely triggered by vibrations from passing trains/vehicles but only created an alarm when the machine was really under attack. |

An attack on a ticket machine can come from any angle and at any time. DC had to develop an ‘always-on’ mechanism of detecting tamper which worked in 3 axis. DC chose to use sensitive solid state micro machines nano technology to detect movements in 3 axis. This was combined with sensor inputs, communications interfaces and alarm driver outputs.
DC developed schematics for the intended design and generated a bills of materials. DC also produced a PCB design utilising industry standard schematic capture and printed circuit board design tools to create the 3 A xis Intelligent Motion Sensing Modules.
The 3 Axis Intelligent Motion Sensing Modules are preset in the factory to detect particular thresholds of movement. If a movement measurement exceeds the preset threshold a message is sent to the system to generate an alarm signal. This notifies the remote monitoring station which is equipped with CCTV to monitor the machines. |

From the start of the project to delivery of the first working prototype took 20 days. The prototype was tested successfully within a ticket machine.
A further 20-off 3 Axis Intelligent Motion Sensing Modules were manufactured in 2 weeks to satisfy urgent requirements. DC then provided volume production units to its client. |
