Alerts are different than alarms.
An alert means a notification of an event that could potentially escalate to an alarm. For example, when you come back home and open the door while the system is armed as Away and walk in front of the Keypad, the Keypad will beep to request the PIN. This is an alert.
Another example is when a Security Camera records a person in your yard while the system is armed as Home or Away. We will notify you about it because this could potentially be a threat. We will not notify the monitoring center when there is an alert but no alarm.
An alarm means an Event captured by sensors (Entry or Motion sensors) is detected as an intrusion. This type of Event will cause Noonlight to inquire about your safety. If you do not cancel the alarm, the monitoring center will dispatch first responders.
