Sigard-Incident Detection

The system is triggered only when it detects the sounds of human aggression, anger or fear. Constant monitoring is therefore no longer necessary.

Sigard improves privacy.

One operator can keep track of more cameras. Staff in the surveillance room and street personnel can be deployed more efficiently.

Sigard increases efficiency.

Sigard substantially reduces the chance of the operator in the surveillance room missing incidents or spotting them too late. The operator can assess the situation better and inform and deploy security personnel more accurately and more appropriately.

Sigard increases effectiveness.

Immediate alarm of important incidents leads to quicker response, often preventing incidents from escalating. This decreases potential harm to people and damage to properties. It increases the chance of arrest and prosecution while decreasing follow-up cost of violent incidents.

Sigard increases safety.

The benefits

Sigard can be used in a variety of public sector and commercial scenarios. Both hot-spots with frequent incidents and locations with low incident rates like parks, pedestrian tunnels or passageways can be monitored without a proportional increase in operator workload.

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.

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.

The Sigard solution

Conventional CCTV systems are primarily used for general surveillance and post incident analysis. In many large control rooms, each operator monitors as many as 120 cameras. With so much information to filter it is highly likely that incidents will occur in areas where cameras are not being actively monitored. This task is made especially difficult because operators are often unable to interpret the true context of a behaviour based on silent video alone.
