Key Aspects of Sensor Alarms:
- Functionality: These devices detect changes in their environment, such as interruption of a light beam, vibration, or sound.
- Types of Sensors:
- Motion Sensors: Use infrared (PIR), microwave, or acoustic technology to detect movement within a designated area.
- Magnetic Contact Sensors: Comprise a magnet and a sensor; when a door or window opens, the magnetic field is broken, triggering the alarm.
- Glass Break Detectors: Utilize acoustic sensors that “listen” for the high-frequency sound of shattering glass, or shock sensors that detect the impact vibration.
- Operation: Upon detecting a threat, the sensor sends a signal to a control panel, which may activate a local siren or send a notification to a mobile phone or monitoring team.
- Placement: Placed at perimeter entry points (doors/windows) or throughout the interior to monitor specific areas.
- Security Use: They are crucial for both residential and commercial safety, acting as reliable, often easy-to-install, security measures
- Batteries not included
