Does the system sound an alarm if there is an intruder?

If you’ve activated the alarms in your house and a family member or roommate comes into the house, the system will detect the person and sound the alarm. If the person has access to the Pro Security app, they can disarm the alarm. If they don’t you can disarm the alarm remotely or through the backup QR code and let the monitoring service know that this person is not an intruder.
