Maptek Sentry

Mobile system for remote, safe surface monitoring

The operator can unpack the system and start monitoring in 15 minutes!

Sentry combines an I-Site laser scanner with sophisticated software to cost-effectively monitor, analyse and report on rapid and gradual surface movements that have the potential to interrupt mining and civil engineering projects. It is deployed in a custom trailer offering a power and communications module, cellular and wifi networking,

You can fully customise monitoring frequency and thresholds to meet your design and planning needs, and report the data geotechnical teams and management need to manage risk.

  • Scan and monitor several zones concurrently and monitor multiple areas within a scene without the need for targets or reference points.
  • Animations show morphology of terrain changes over time. Timelapse capability provides insights to predict movement in other areas.
  • Heatmaps coloured by displacement or velocity provide an overview of movement.
  • Combine true 3D measurement with 3D photographs, visualisation and analysis tools for site-wide risk management.
  • Easily definable alerts and notifications send critical information directly to geotechnical staff or mine managers.

The Sentry difference

  • Efficient and cost-effective monitoring system
  • Designed for use in rugged mining environments
  • Operates in low light for underground and night time monitoring
  • Simple to set up and operate in remote locations
  • Quantify volume of material moved during rock failure
  • Heat map and imagery provides an overview of surface movement
  • User defined legend to quickly identify changes
  • Automatically generate displacement, velocity and inverse velocity graphs
  • Apply previous monitoring data to create timelines
  • Generate and animate zones to show movement over time
  • Use laser scan data for survey applications and geotechnical analysis
  • Export data to PDF and MS Excel formats for easy sharing
  • Various configurations available to suit site requirements
  • Compatible with I-Site XR3, I-Site LR3, I-Site 8820 and I-Site 8200ER/SR laser scanners
