Maptek Sentry

Mobile system for remote, safe monitoring

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

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

Users can fully customise monitoring frequency and thresholds to meet strategic design and operational planning needs, and provide accurate, timely reports to geotechnical teams and management who 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 before failures occur.
  • Heatmaps coloured by displacement or velocity provide an overview of movement that can lead to failures such as landslides or rockfalls.
  • Combine true 3D measurement with 3D photographs, visualisation and analysis tools for strategic risk management.
  • Easily definable alerts and notifications send critical information directly to geotechnical staff or mine managers in near real time.

The Sentry difference

  • Cost-effective monitoring system for strategic risk management
  • Designed for rugged mining environments
  • Operates in low light for underground and night time monitoring
  • Simple set up and operation for tactical monitoring in remote locations
  • Quantify volume of material moved during rock failure
  • Heat map and imagery provides an overview of slope movement
  • User defined legend to quickly identify changes in slope stability
  • 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 XR3, LR3, SR3, I-Site 8820 and 8200ER/SR laser scanners


Highwall Monitoring

Improve pit safety and risk monitoring by early detection of highwall, bench and slope movements.

Wall and Stability Monitoring

Reduce risk by early detection of surface movements and moisture.

Underground Monitoring

Improve safety underground by early detection and notification of surface movements.

Case Studies

Gaining control over potential instability

The first Maptek Sentry monitoring system implemented in Peru will be used for managing geotechnical risk at a large iron ore mine.
