Sigard audio analytics is a very reliable method of automated detection to combat crime and anti-social behaviour. 90% of all incidents involving physical aggression are preceded by verbal aggression. The ability to spot verbal aggression before it turns into a violent outbreak delivers valuable time to operators and enables speedy intervention.

Sigard is based on sophisticated sound detection and analysis software that isolates specific sound patterns from the overall ambient sound picture. It dissects and looks for clues in the sound, much like the human hearing does. Whenever a microphone in the Sigard detection system registers the typical sound characteristics of human aggression, anger or fear, the system will send out an alert. This will trigger the camera nearest the incident and alert the operator in the control room.
