alarm systems
Home protection technology
Alarm systems are networks of sensors and alerts designed to detect and warn of intrusion, fire, or other dangers.
Home alarm systems typically include door and window sensors, motion detectors, and a control panel connected to a monitoring service.
The term extends to car alarms and commercial security installations: We had an alarm system installed after the break-in.
