What is a security alarm system?
A security alarm system is a device or combination of devices designed to detect unauthorized entry into a building or area. These systems typically include sensors, control panels, and alert mechanisms such as sirens or if required notifications to a monitoring center.
How do security alarms work?
Security alarms use sensors to detect breaches. Common types of sensors include:
- Motion Detectors: Detect movement in a specific area.
- Door/Window Sensors: Trigger when a door or window is opened.
- Glass Break Sensors: Detect the sound of breaking glass.
- Cameras: Provide visual monitoring and sometimes include motion detection.
When a sensor is triggered, the system alerts the user or monitoring service via an alarm, app notification, or call.
What are the types of security alarm systems?
- Monitored Systems: Connected to a professional monitoring service.
- Unmonitored Systems: Sound an alarm locally but don’t notify a monitoring center.
- Wireless Systems: Easy to install, communicate using Wi-Fi or cellular networks.
- Wired Systems: Hardwired into the building, often more reliable but harder to install.
