How It Works

From audio capture to cloud monitoring — a four-stage pipeline.

Detection pipeline

1
Camera captures audio
Existing cameras stream audio through NX Witness VMS — no new cameras required
2
On-site AI inference
Cochl-certified hardware runs the AI model locally — raw audio never leaves the site
3
Event metadata sent to cloud
Only metadata (sound type, timestamp, camera ID) is transmitted — no audio
4
Dashboard + alerts
View real-time events and receive webhook / email notifications

System components

VMSExisting video management environment — NX Witness currently supported. Additional VMS platforms will be supported in future updates.
Cochl PluginExtracts audio streams from the VMS
Cochl HardwareRuns AI inference on-site (required for paid plans)
Cloud DashboardReal-time event monitoring, history, and notifications
For the Trial tier, Cochl-certified inference hardware is not required. NX Witness VMS and the Cochl plugin must still be installed.
