Inspection Systems

See What You’re Missing.

Our inspection technologies are ideal for pipelines too small to allow man entry, including water and wastewater collection and conveyance systems. Solutions include CCTV, sonar profiling, 3-D, and point cloud data capture. Much of our CCTV equipment is built around single conductor technology, which accommodates all power feed and command functions in a single steel-wrapped cable to make our equipment less bulky, easier to control, and far more durable than typical multi-conductor technology.

More Than 30 Years of Innovation.

Our inspection system technology traces its roots back three decades with many innovative “firsts” to the marketplace.

  • First mainline color camera featuring internal lights.
  • First U.S. manufacturer to build a true pan-and-tilt camera with tracking lights.
  • First to manufacture cable reels that offer “electrical gear selection” and a true freewheeling cable drum.
  • First tractor design to provide freewheeling for rapid return.
  • First to design an electronic circuit to double tractor torque without increasing supply current.
  • First to introduce a steerable storm drain tractor or large pipeline tractor.
  • First U.S. company to design an explosion-proof camera and tractor approved for Class I Division I applications.
  • First to design a universal tap-cutting control system for single-conductor camera systems.
  • First to design single conductor laser and sonar profiling systems.
  • First manufacturer to produce a single conductor panomorphic camera system.

Single-Conductor Technology.

Our single-conductor technology is a version of the same coaxial cable that reliably delivers hundreds of TV channels, high-speed Internet, voice communication, and more to millions of households and businesses across America. The advantages over competitive multi-conductor cable is clear:

  • Video signal quality is not affected by the length of cable (unlike multi-conductor technology).
  • Single-conductor cables offer a life expectancy at least three times that of any multi-conductor cable.
  • Single-conductor cable has a breaking strength greater than 5,000 pounds (typical multi-conductor cable has a breaking strength of 2,000 pounds or less).
  • Single-conductor cable is simple to maintain and the end connectors can be replaced in a matter of minutes. Multi-conductor cable typically requires several hours of labor and advanced technical skills to splice or troubleshoot multiple wires.
