A perimeter intrusion detection system (PIDS) is only as good as its fit to your site. The right choice depends on perimeter length, environment, threat profile and the acceptable false-alarm rate.
Fence-mounted PIDS such as Flexiguard™ uses a microphonic sensor cable to detect the vibration of an intruder cutting or climbing the fence. It is ideal where a physical fence already exists and precise, zone-by-zone localisation is required.
Where there is no fence, or open ground must be covered, volumetric technologies come into play. Omni Guard Radar and Microguard™ microwave barriers create invisible detection fields across sterile zones and approaches, providing early warning before an intruder reaches the boundary.
In practice, the strongest perimeters layer these technologies together - fence PIDS for the line, radar for the open ground - unified within a single command platform so operators see one coherent picture.
