Maptek Sentry

Versatile solution for change detection

Maptek Sentry is a flexible and cost effective solution for detecting surface change. The system combines I-Site laser scan data with sophisticated software to track and analyse movement over time.

The Sentry system helps sites monitor and report on movements caused by surface instability that have the potential to interrupt mining activity. Multiple zones can be tracked within a wider area of interest.

Sentry is capable of measuring changes resulting from rapid movement. Monitoring frequency and notification thresholds are fully customisable, providing accurate, useful results for mine design and planning.

Sentry monitors and maps the complete scene, producing a true digital terrain model for 3D viewing. The system is easily mobilised and can be set up repeatedly over the same location while maintaining monitoring history.


Highwall Monitoring

Maptek Sentry helps improve pit safety by early detection of highwall, bench and slope movements.

Tailings Dam Monitoring

Maptek solutions help reduce risk by early detection of surface movements and moisture leakage in highwalls and tailings dams.

Underground Monitoring

Maptek Sentry helps improve safety underground by early detection and notification of surface movements.

The Sentry difference

  • Lower cost than alternative monitoring systems
  • Designed for use in rugged mining environments
  • Operates in low light for underground and night time monitoring
  • Simple to setup and use with low power consumption
  • Integrated weather station corrects scan range for temperature and atmospheric pressure
  • Use laser scan data for survey applications and geotechnical analysis
  • Quantify volume of material moved during rock failure
  • Heat map and imagery (I-Site 8820 series) provides an overview of surface movement
  • User defined colour palette to quickly identify changes
  • Automatically generate displacement, velocity and inverse velocity graphs
  • Export data to PDF format for easy sharing
