Audio Sensors

Audio sensors detect noises generated by an intrusion attempt into a protected area. This type of sensor is typically used to monitor indoor facilities such as critical storage areas, entrance foyers, and so forth.

 

 

Principal Drawback

Audio sensors must be mounted in areas where the noise generated by an intrusion attempt is expected to exceed normal environmental noise. Since loud background noise is common in outdoor applications (e.g. passing vehicles, thunderstorms, aircraft over flights, etc.) audio sensors are typically not recommended for perimeter monitoring purposes.

Other Shortcomings:

  • Intrusion attempts may not generate enough sound to trigger sensor
  • Sensors require electricity

Fiber Fence Advantages over Audio Sensors:

  • Not affected by environmental noise
  • Sensors do not require electricity
  • Can be calibrated to eliminate nuisance alarms
  • Designed specifically for Perimeter Monitoring
  • Economical to purchase
  • Easy to install
