Electric Field

Electric field sensors work by generating an electrostatic field between wire conductors and an electrical ground. Sensors are designed to detect distortions in the field, such as that cased by someone who approaches or touches the perimeter fence.

 

Principal Drawback

Adverse weather conditions, including rain, snow and lightning storms can degrade the reliability and performance of the system.

Other Shortcomings:

  • High component / installation costs
  • Animal movement and vegetation along the fence line can cause the sensors to trigger.
  • Sensors require electricity

Fiber Fence Advantages over Electric Field Sensors:

  • Sensors do not require electricity
  • Can be calibrated to eliminate nuisance alarms
  • Not affected by electric field generated by lightning storms
  • Not affected by rain and snow
  • Economical to purchase
  • Easy to install
