Alarm.com does not monitor the systems in a traditional sense.
Alarm.com through suretyDIY is a remote access service connecting your panel to your smartphone, tablet, laptop, to allow control and data viewing. You can set up custom notifications based on the equipment tied to your system which can be sent as text message, push notification, and/or email to your devices. The notifications are generated based on the triggers and filters you choose. Some example cases and videos below:
Alarm signals from your panel
Sensors left open for a period of time
System not disarmed by a specific time
Environmental alerts like flood sensors, high temp alerts
Forgot to close the garage door
Someone opened the liquor cabinet/safe
24/7 Central Station Monitoring can be included or omitted from your Alarm.com service through suretyDIY. Central Station Monitoring refers to professional monitoring center operators calling you in the event of an alarm, and contacting local police/fire/medical authorities when needed.
Central Station operator standard procedure based on the type of alarm signal can be found here.
