Motion detectors and door/window sensors are activated, and your control panel is at the ready or “armed mode”. If someone were to break into your home or office, your alarm would sound—but who would respond if you weren’t home or couldn’t answer?

When your alarm is triggered, it will notify your monitoring company so that a representative can alert authorities to check out the issue and provide assistance if and when needed. – Source: Link
