Perimeter Intrusion Detection Systems
(PIDS) – Case Study

Client Profile

A 250‑acre power generation facility with critical assets including substations, fuel storage, and control rooms. The site handled thousands of personnel and vehicles daily, with perimeter spanning over 8 km of fencing and open terrain.

Key Challenges

• ✗ Frequent perimeter breaches (average 12/month) via fence cutting and open areas
• ✗ Legacy fence sensors generated 85% false alarms (animals, weather)
• ✗ No real‑time correlation with video – delayed incident verification
• ✗ Inability to detect intrusions in dark or foggy conditions

Phase 1 – Assessment

Perimeter walk‑down, risk analysis, sensor placement design, and integration planning (4 weeks).

Phase 2 – Installation

Fiber optic cabling, microwave barrier alignment, thermal camera mounting, and network integration (6 weeks).

Phase 3 – AI Training

Machine learning models trained to distinguish human intrusions from animals/vehicles, reducing false alarms.

Phase 4 – Handover

24/7 monitoring handover, staff training, and SLA‑based maintenance (2 weeks).

Security Improvements

• 95% reduction in successful perimeter breaches
• 90% reduction in nuisance alarms (from 85% false positive rate to 8%)
• 100% coverage of all perimeter zones
• Average alert-to-verification time: <5 seconds

Operational ROI

• ₹42 lakh annual savings in security manpower and incident response
• 70% reduction in security patrol hours
• Zero security‑related regulatory penalties in 18 months
• ROI achieved in 11 months
