Currently, the only audio detection supported by Reolink cameras is cry sound detection.

Cry sound detection uses pre-trained learning algorithms to identify audio features matching a baby’s cry. These models are trained on large datasets of baby cries to recognize unique sound patterns.

When the camera detects a cry that meets the preset criteria, it automatically triggers an alert—such as sending a push notification to your phone or starting a recording—so caregivers can respond quickly.

The table below lists the models and hardware requirements that currently support cry sound detection:

How to Enable Cry Sound Detection

  1. Open the Reolink App.

  2. In Push Notification schedule settings (you can also choose other alarm actions, such as recording or email alerts), check Cry Sound Detection.
  3. Save your changes.
