Chapter 13. Build a Security System > Monitoring and Alerting

13.6. Monitoring and Alerting

The monitoring component of a security system ties all the other components together. It receives signals from the different intrusion detection mechanisms, and determines whether it needs to take action based on whether the alarm system is armed. If it does need to take action, it starts up the intrusion deterrence mechanisms by turning on the lights and sounding an alarm. If available, it'll record video and ship it off-site. It will also notify you somehow, either audibly or by sending a message to your phone, email address, or pager.

13.6.1. 1. Install remote speakers

Luckily, not every type of alarm calls for a blaring siren. For example, if a sensor has detected water in your basement, what you'd really like is a calm voice telling you that a leak has been detected. A voice response system would also be useful if an intruder was detected, because it could tell you exactly where the intrusion was detected—allowing you to go directly to the problem, rather than checking every door and window.
