Listens to camera audio for gunshots, breaking glass and screams and raises an immediate critical alert, even when the source is out of view. Works on any camera with 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. Sudden sounds such as gunshots and breaking glass must pass a strict threshold, and screams must persist before an alert fires, 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.
What Audio Event Detection does for your team.
Detects gunshots, breaking glass, and screaming directly from camera audio and raises a critical alert.
Sudden sounds must pass a strict threshold; screams must persist for a moment before alerting.
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.
Each camera learns its own background noise level, so a naturally loud environment does not keep raising false alarms.
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.

Gunshots, breaking glass and screams, from cameras with microphones.
Sound reaches places a camera cannot see. A scream around a corner or glass breaking out of view still raises an alert on the wall, so nothing important is missed.
Yes. Each camera learns its normal background noise, so busy environments do not set off constant alerts.
