How to make a Driver Monitoring System (DMS) works interactively and automatically?
The Driver Monitoring System allows you to receive timely information about critical events, such as driver fatigue, the use of a mobile phone, an unfastened seat belt and many others.
However, in most cases, the system responds in a standard manner - notifies the driver and dispatcher. But these actions are clearly not enough in critical cases, for example, when the driver falls asleep or enthusiastically chatting in a mobile phone, not paying attention to the environment and warning by the monitoring system.
We believe, that in such cases, automatic forced reduction of speed up to a complete stop is an effective method of maintaining driver, passengers,cargo and road safety.
The smart Speed Limit Device  http://xmetra.com/speed-limit-device-sld/  was specially developed for use in conjunction with Driver Monitoring and Telematics (Tracking) Systems  and can be installed virtually on any vehicle and quickly integrated with already installed telematics terminals and monitoring software.
