The sensitivity required to trigger a noise or motion alert is adjustable. Calibrating these settings to your needs allows the cameras to only record videos and send notifications that are important to you, rather than every noise or motion in the camera's area.
To access the sensitivity slider for a detection type, the alert needs to be set to "On". A slider set far to the right will trigger events for subtle movements and quiet noises. Conversely, a slider set far to the left will require louder sounds or greater movements to trigger an alert.
