Automated Monitoring Solutions 

SiteMonitor4D is a system for monitoring change

The system provides georeferenced datasets so that you can obtain a better understanding of historical behaviours and deformation of large scale areas.

Why? - To allow you to make informed decisions regarding the change detected.


  • Automatic (Continuous) or Periodic data capture
  • Precise and accurate measurements
  • Simple and reliable hardware
  • Wizard-based setup allows personalized monitoring schedules


  • Visualise, examine and analyse your data
  • Identify and query movement with the Analytical Toolbox
  • Track displacement through time. Correlate results with external datasets
  • Conduct geotechnical analyses to understand displacement styles
  • Create figures and reports to communicate and share results easily


  • Improve Safety: Alarm your data to mitigate against failure in real time
  • Early detection of surface movements and moisture leakage
  • Improve decision-making with real, easy to understand evidence

SiteMonitor4D can be used for a wide range of applications such as:

Open Pit Mining:

  • Slope stability assessment
  • Mine plan conformance analysis
  • Volume measurement
  • Underground deformation.


  • Landslide monitoring
  • Avalanche monitoring
  • Coastal Erosion
  • Seismic displacement
  • Rockfall analysis
  • Volcano monitoring


  • Building and structural health monitoring
  • Bridge monitoring
  • Dam safety monitoring
  • Road network monitoring

Security and Defence:

  • Ground disturbance
  • Aerial surveillance
  • Foreign object identification

Continuous Mode
In this scenario, the laser scanner would be set up in a protective housing, with a mains power supply and a stable pillar on which it can be mounted.
A number of reflectors installed around the monitoring region(s) enable the Range Correction Factor (RCF) to be calculated and the stability of the scanner to be monitored. If the scanner needs to be moved, the reflectors allow the monitoring project to be resumed at a later date.
Once a scanning schedule is defined, the software can run automatically without further operator intervention. All data is transmitted live to an office-based computer running SiteMonitor4D Analysis, allowing rapid evaluation by surveyors and geotechnical engineers.

Periodic Mode
The scanner can be removed between surveys if continuous monitoring of a site is not required or the scanner may be removed between surveys for security or discretion.
Following the quick setup of a monitoring project, subsequent data collection surveys can be carried out by simply setting up the scanner, scanning a number of control points (to provide an orientation and a range correction factor) and re-scanning the areas of interest. Data gathered during periodic monitoring can be transmitted back to SiteMonitor4D Analysis on a remote link or downloaded by the operator when the field work is complete.

If you're not sure of the words used please see our ‘Laser Scanning Jargon’ page for definitions of technical terms.

High Resolution Camera: Capture geo-referenced images for data visualisation, interpretation and analysis.

Advanced Laser Scanning Technology: Up to 4,000m range, up to 222,000 points per second, accuracy of geo-referenced data is typically better than 10mm.

Monitoring Sensors: Integrate external sensors for a complete monitoring overview. (GPS and GNSS systems, alarms, total stations, wireline extensometers, piezometer, security sensor, webcams, tilt meters, inclinometers, weather stations.)

Data from these inputs are then transmitted to a server, and displayed to you on your computer or  tablet using SiteMonitor4D software.

In our current era we are employed within a demanding and dynamic mining environment where mechanization is a keyword used and applied. The SiteMonitor setup and Acquisition module has really catered for this in the sense that it simplified human interaction and increased safety and productivity within this arduous environment.

Frans Benadé, Section Surveyor at Mogalakwena Mine.

Using the SiteMonitor software has been a great experience for me. One of the major challenges faced by Geotechnical Engineers in open pit mines was the current lack of a system for rock fall risk management. The site monitor software provides a solution to this problem. It … enables us to assess the risk and to ensure that appropriate rock fall risk mitigation is in place. There is no other system currently in the market that is capable of offering the same functionalities.
