alarm system
Motion-triggered siren network
An alarm system is a network of sensors and devices designed to detect and alert people to unwanted events, most commonly break-ins or fires.
Home alarm systems typically include door and window sensors, motion detectors, and a control panel that triggers a loud siren or notifies a monitoring service when activated.
Businesses and institutions use more elaborate systems that may include surveillance cameras and access control.
The alarm system went off when someone tried the back door.
