Technology

Remote Visual Inspection or Remote Digital Video Inspection, also known as RVI is a form of visual inspection which uses visual aids including video technology to allow an inspector to look at objects and materials from a distance because the objects are inaccessible or are in dangerous environments.[1] RVI is also a specialty branch of nondestructive testing (NDT). Technologies include, but not limited to, rigid or flexible borescopes, videoscopes, fiberscopes, push cameras, pan/tilt/zoom cameras and robotic crawlers. RVI is commonly used where distance, angle of view and limited lighting may impair direct visual examination or where access is limited by time, financial constraints or atmospheric hazards. RVI is commonly used as a predictive maintenance or regularly scheduled maintenance tool to assess the “health” and operability of fixed and portable assets. RVI enables greater inspection coverage, inspection repeatability and data comparison. The “remote” portion of RVI refers to the characterization of the operator not entering the inspection area due to physical size constraints or potential safety issues related to the inspection environment.
