SecurePerimeter-LRF
1. Overview
The SecurePerimeter-LRF is an advanced perimeter security module designed for the protection of large-scale strategic facilities such as nuclear power plants, seaports, oil depots, and other critical infrastructure.
It integrates a long-range laser rangefinder (LRF-50) with a PTZ video surveillance system, enabling both continuous perimeter scanning and precision tracking of moving objects in real time.
This device provides automatic intruder detection, distance measurement, and coordinate calculation, significantly improving situational awareness and security response capabilities.
2. Key Features
- Integrated System: Combines LRF-50 laser rangefinder with PTZ optical/thermal cameras
- Long-Range Monitoring: Effective object detection up to 7 km
- High Precision: Distance measurement accuracy up to ±5 cm
- Automatic Intruder Tracking: Detects moving objects and calculates their coordinates in real time
- IoT & VMS Integration: Compatible with major video management systems (Milestone, Genetec, etc.) and IoT platforms
- All-Weather Operation: Resistant to fog, rain, and snow; operates 24/7
- Fail-Safe Security: Generates alerts in case of suspicious movements, enabling rapid operator response
3. Applications
- Nuclear Power Plants – protection of reactor and storage zones
- Seaports & Airports – prevention of unauthorized perimeter breaches
- Oil & Gas Terminals – monitoring of vulnerable storage and transport areas
- Military Bases & Government Facilities – critical perimeter defense
- Industrial Complexes – safeguarding production assets from intrusion

5. Functional Workflow
- Scanning: LRF-50 continuously scans the secured perimeter
- Detection: Moving object detected within the laser beam
- Measurement: Exact distance to the object is calculated
- Identification: PTZ camera auto-focuses on the target
- Tracking: System calculates precise intruder coordinates (X, Y, Z)
- Alerting: Operator receives alarm + video feed + target coordinates
- Response: Enables rapid security force deployment or automated defense protocols
6. Benefits
