3.1. Main Functions
The ATD-300 (white version) and the ATD-301 (black version) are the next generation Acoustic
Threat Detection system designed to protect public places. The technology used was proven on
the military field for 25 years.
The pod has the ability to detect, identify and localize a gunshot, a sniper or firecracker. All
these treatments are performed on edge to have a fast and reliable alarm in case of threat.
The threat detection and identification is not based on simple threshold, but on more than 90
acoustics parameters computed in real time and analyzed with a specific Artificial Intelligence
trained on our real gunshot database collected all over the world for more than 25 years. This
high performance process limits the number of false alarms and allows you to have the accurate
information in a few seconds.
In addition, the pod has a 4 microphones antenna covered by the windscreen, with this antenna
and specific algorithm on edge, one pod is able to compute the azimuth and the elevation of the
gunshot. In case of a Sniper, if the pod catches the nozzle noise and supersonic bullet noise,
one pod is able to compute the azimuth, the elevation and the distance of the Sniper. If only
supersonic bullet noise is heard by the pod, in this case the localisation is impossible but the
pod will push an alarm to a server or VMS.
As soon as the pod localises a threat, it will move a colocalized PTZ camera directly on the
threat root, in the same time alarm will be pushed to a server or a VMS to focus the operator on
the threat.
In normal circumstances, the pod pushes the sound level every second, with this simple
indicator, it is easy to know if there is activity in a specific area.
