Listens to camera audio for gunshots, breaking glass, and screaming and raises an immediate critical alert for operator review. It confirms a sound across several consecutive seconds before alerting to suppress false alarms, and works on any camera that has a microphone.
Visylix Audio Event Detection adds a listening layer to your cameras, watching the audio for the sounds that signal trouble even when nothing is yet visible in frame: a gunshot, breaking glass, or a scream. It raises a critical alert the moment a sound is confirmed, so your team can look at the camera and respond in seconds. Because a false acoustic alarm is disruptive, it confirms a sound across several consecutive one-second windows before alerting, which keeps nuisance alarms low. It runs on any camera that carries a microphone with no dedicated acoustic sensors to install, and is designed as an assistive alert for operator review: it pairs an instant notification with the triggering camera so a person can verify and escalate. It suits schools, retail, transport hubs, and any site where an early warning of a violent or destructive event matters.
Core capabilities of the Audio Event Detection model.
Detects gunshots, breaking glass, and screaming directly from camera audio and raises a critical alert.
Confirms a sound across several consecutive one-second windows before alerting, cutting false alarms.
Raises a high-priority alert linked to the triggering camera the moment a sound is confirmed.
Uses the audio your cameras already carry, with no dedicated acoustic sensors to install.
Tune how readily each camera alerts and which sounds it listens for to match its environment.
Hears trouble even when the source is out of view or in the dark, complementing the visual models.
Designed as an assistive alert for human review and escalation, not an autonomous action.
Delivers alerts through the dashboard, SMS, email, and webhook the moment a sound is confirmed.
Real-world applications for Audio Event Detection.

Alerts security to breaking glass or a gunshot at entrances and after hours.
Listens for screams and gunshots across busy stations and terminals.
Hears breaking glass and violent events in dark or unmanned areas cameras cannot always see.
Flags screaming or a gunshot in lobbies and waiting areas for staff to act on.
