Alert all authorized personnel in just a few seconds, while alerting the authorities and creating a geofence for a precise reaction.
Safe Wave uses high-frequency sounds, inaudible to the human ear, to emit a silent alert signal to trained personnel, through any PA system, without requiring an internet connection.
It has been designed as a fault-tolerant system that combines high-frequency sounds, internet and messaging to ensure that the alert reaches its destination.
