Maptek Sentry

Mobile system for remote, safe monitoring

Set up and start monitoring surfaces in minutes!

Sentry combines a Maptek 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 various configurations, the most flexible 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 for managing risk and safeguarding operational environments.

  • 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. Apply a user-defined legend to quickly identify changes.
  • 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


Sentry is a cost-effective monitoring and mapping system for strategic risk management. It is designed for rugged environments and operates in low light for underground and night time monitoring. A new Sentry configuration allows for continuous monitoring in -20°C, with limited operation at temperatures down to -40°C.

Sentry hardware and software is simple to set up and operate for tactical monitoring in remote locations. Previous monitoring data can be used to create timelines, and generate and animate zones to show movement over time.

The ability to view and analyse automatically generated displacement, velocity and inverse velocity graphs in the pit or underground, in operational offices and remotely over a network helps ensure safe operating conditions 24 hours a day.

In the event of failures, users can import data into Maptek PointStudio to quantify volume of material moved during rock failure, conduct geotechnical analysis and plan remediation work.

Sentry cold climate system

The Sentry cold climate system can operate for hours in temperatures from -20°C to +50°C, with a limited operating window in temperatures below -20°C. The battery pack and housing is insulated to keep the unit at a stable operating temperature. Generator, hydraulics and electrical systems help maintain energy efficient, cost-effective operation while monitoring. The system requires a Maptek XR3 cold climate laser scanner, which has also been redesigned to operate at lower temperatures.


Highwall Monitoring

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

Tailings Dam 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

Slope stability risk management

Laser scanners are ideal for volumetric survey, geological and geotechnical data analysis, and tactical and strategic slope deformation monitoring.

Monitoring tailings dams

Continuous monitoring using Sentry provides effective risk management for tailings dams.

Stability monitoring for peace of mind

Continuous monitoring using Maptek Sentry provided effective risk management during equipment maintenance at an Australian mineral sand operation.

Periodic monitoring with Sentry

Sentry Patrol watched over workers during the successful remediation of a rockfall at Kanmantoo Copper Mine, allowing operations to quickly resume.

Highwall stability in longwall mining

A coal mine in Central Queensland used Maptek Sentry monitoring to help predict highwall movement associated with longwall subsidence

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.
