The Challenge
G4S partner Controlware Communications Systems is a worldwide company whose interests include communications, professional network services and video surveillance. Their requirement was to network video surveillance for G4S between 600 remote sites across the UK, and Controlware's VAS2800 Video Alarm System was chosen to implement this. The VAS2800 incorporates video, audio and alarm inputs and has a built in ISDN modem to dial back to a remote PC (over either one or two 64k ISDN lines) when an alarm is triggered. The project involved using the VAS2800 equipment installed at each remote site to detect when a visitor presses a door button, and then dial through to a centralised manned facility where the agents on duty can see and talk to the visitor and control the door.
Controlware needed an intelligent call router to take data calls from the VAS2800 units and distribute them evenly to a pool of PCs running their video decoder software. They tested a number of call routing solutions from different manufacturers but they all had one major problem - they could not distinguish between calls from separate VAS2800 units, or ensure the integrity of two 64k ISDN calls from a single VAS2800 unit. |

The Solution
Encoded designed and built a call router intelligent enough to recognise that two 64k ISDN calls from a single VAS2800 unit should be routed to the same PC. It also presents video calls to each PC in least-used order to ensure that each agent has a fair workload, and also allows agents to log on and off from the system. The project took just 4 weeks from design to deployment, and was released on time and within budget. |

The Result
G4S, a major security services provider, can now efficiently control hundreds of remote entry systems from a central location 24 hours a day with up to just 6 personnel on duty at any one time. The system requires no maintenance and provided seamless integration with Controlware’s other systems. |
