tHE second Generation Slideminder

  • Field proven to withstand rugged conditions and extreme temperatures

  • Wi-Fi and FHSS radio technologies do not interfere with existing communications. Internationally complient 

  • Complete customization of alarms allows geotechnical personnel to set user-defined warnings for multiple velocities and displacements for each machine

  • Warnings and alarms can activate strobes and be sent via cell phones, web browsers, and e-mail

  • Stand-alone system operates remotely and requires very little maintenance

  • Software utilizes web-based graphing engine that can be viewed and controlled on any computer on the network

  • Allows monitoring throughout a slope failure without damage to the unit

  • Powder coated NEMA4 enclosure

  • Measurements: 16x12x7 inches


The SlideMinder Slope Monitoring & Warning System works using our proprietary server software, OREAD. Easy to use and reliable, OREAD uses an intuitive graphical user interface. The Web-Based design allows easy access for authorized users from multiple locations. 

Easily graph the following.

  • Displacement

  • Velocity

  • Inverse Velocity

  • Battery Voltage and Recharge

  • Temperature

  • Precipitation



OREAD is also where users set and edit Alarms.  Alarms are designed to activate warning devices, if desired, send out emails or text messages to appropriate personnel when specified slope displacement and/or velocities are exceeded. OREAD is included and installed with the initial SlideMinder installation.
