The importance of eCall

As every second counts in the event of a serious crash, it is our mission to minimise the response time of emergency services. Car crash trauma victims who receive treatment within the first 60 minutes after a serious incident (The Golden Hour) have up to a 50% higher chance of survival and also a much lower rate of long-term disability.

In the event of a severe accident, how do you call for help with your mobile phone?

If your phone is destroyed?

If you are unsure of your exact location?

If the battery is flat?

If you have zero network coverage?

If you are unconscious?

If no one answers your call?

eCall Vehicle Emergency System

6 lives a day.
42 lives a month.
2500 lives a year.

IMR Sentinel has been designed from the ground up to comply with eCall; the Pan-European cellular emergency system for motor vehicles. The EU has estimated that the introduction of the eCall directive will save 2,500 lives per year across the EU through faster response times. By knowing the exact location and time of an accident it is estimated that there will be a 50% reduction in response times in rural areas and 40% reduction in response times in urban areas throughout Europe. The EU has mandated that all new type of cars sold after March 2018 will require an eCall-compliant crash alert device.
