Today,when a fire breaks out,you can be sure a citizen with a cellphone camera has posted it to Facebook or Twitter,or sent it to the media.But up to now,that citizen has not been able to easily send images and details of what is happening to the people who need it most:the police,firefighters and building-security people who must respond,and whose ability to help is often measured in minutes,if not seconds.
That’s about to change.A one-year-old company called Elerts has developed a system that’s designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger.The system involves free mobile applications—iPhone and iPad app (应用软件) is available now—that eyewitnesses can use to report incidents and get public safety warnings.And Elerts is offering a management console (控制台)for security firms and universities to receive the reports and distribute warnings and instructions,like a map with the best evacuation route (疏散路线).
The service is the brainchild of Chris Russo,deputy fire chief in
the
coastal
town
of Hull,Mass.As
mobile communications sped up,he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public,particularly with people who are at the scene and might be able to provide help.
