UnderCover® Manhole Security System

UnderCover® is a real-time, self-contained, monitoring system providing intrusion detection and alarms for sewer, water or storm water manholes, utility vaults, and other lid or manhole-accessed spaces. It is both a standalone intrusion detection system or can be used in conjunction with liquid level sensors.

The UnderCover® system includes four basic components:

  • an entry sensor such as a MEMS device or limit switch
  • two-way wireless communications network
  • data storage and analysis
  • decision and action support


  • Reduce Operational Risk.
  • Know When and Where Your System Has Been Accessed.
  • Get Ahead of Potential Problems.
  • No Need for Local Power or Communications to Operate System.
  • Monitor Remote Locations.
