Envirosight”s QuickView zoom camera is a sewer and pipeline inspection tool that allows an operator to measure distance and view far-away objects. The camera measures the distance to in-focus targets and displays the reading on a screen. An operator finds an object, focuses on it, and presses the “measure” button on the controls. This feature is a good fit for correlating taps to residences, troubleshooting backups, and identifying the location of problems such as offsets, root balls, and debris. The camera calculates distance based on the camera’s focus and zoom settings, achieving accuracy of +/- 10 percent over a range of 20 to 160 feet. The measurement appears onscreen as a distance range, which takes this accuracy into account. Readings can be configured for standard or metric units.
