Like many industries, sewer inspection benefits from technologies developed elsewhere—typically for consumer goods (microcameras, digital video, digital control networks), or for larger industrial sectors (XYZ probes, profiling, laser distance measurement). There's certainly been no shortage of technological innovation in the past two decades. Ultimately, manufacturers must place bets on which specific technologies offer true benefits to sewer inspection professionals and develop products that leverage them. Generally, they succeed when the technology offers new efficiency (demanding less time, lower cost or fewer resources), improved safety or enhanced data. Side-scanning technology is unique in that it offers a multitude of efficiency gains and a better quality deliverable—and that's one reason why so many manufacturers have recognized it as part of sewer inspection's future.
