Egoza concertina wire can be easily turned into an intelligent barrier if the vibration cable is properly attached and analytics are correctly configured. Untrained contractors often secure the sensor to the tape surface or ignore segment length, resulting in a flood of false alarms. Here is an algorithm that reduces them to ≤3 per month.
Choosing the Sensitivity Level
- Storage facilities – 6-8 mV/g.
- Airport perimeter – 4-5 mV/g.
- Military sites – 2-3 mV/g + dual-trigger logic “impact+displacement”
Cable Attachment Guidelines
- Secure the cable to the core wire, not to the tape – ensures uniform sensitivity.
- Clamp spacing – every 400 mm, cable rotated 45° from vertical – minimizes contact noise.
- Route the cable at the “six o'clock” position – protection against lateral tool strikes.
Line Segmentation
Ideally, install one controller every 100 meters. Longer segments increase capacitive noise and reduce detection accuracy.
Calibration and AI Filtering
- “Thermometer” scenario – gentle touch with a metal rod → baseline threshold.
- “Scissors” scenario – cutting the side blade → baseline + 40% adjustment.
- “Cat” scenario – animal jump impact → filter out frequencies above 300 Hz.
Integration with VMS
Alarm events are transmitted via ONVIF. In your VMS, create a rule: “Sensor event + object detected in camera zone for 3 seconds” – this reduces false dispatches by 28%.
Annual Maintenance Checklist
- Check the tension of the core cable and replace any damaged clamps.
- Take five random signal measurements and compare them to the baseline.
- Update the controller firmware (minimum version 3.2 to support TLS 1.3).
