Reverse 9-1-1

Reverse 9-1-1 is a public safety communications technology used by public safety organizations in Canada and the United States to communicate with groups of people in a defined geographic area. The system uses a database of telephone numbers and associated addresses, which, when tied into geographic information systems (GIS), can be used to deliver recorded emergency notifications to a selected set of telephone service subscribers.[1]

Background

Reverse 9-1-1 was developed by Sigma Micro Corporation, later known as Sigma Communications, in 1993.[2] After a number of corporate acquisitions, Motorola Solutions ultimately gained ownership of the technology and rights developed by Sigma, and Motorola has folded Reverse 9-1-1 into their Vesta suite of public safety systems.[3]
