Remote Visual Inspection (RVI)

Remote Visual Inspection (RVI) or Remote Digital Video Inspection (RDVI), also known as RVI or RDVI, is a type of visual inspection that employs visual aids such as video technology to allow an inspector to examine objects and materials from a distance because the objects are inaccessible or in hazardous environments. RVI is also a subset of non-destructive testing (NDT). Borescopes, videoscopes, fiberscopes, push cameras, pan/tilt/zoom cameras, and robotic crawlers are examples of technologies. Remotes are commonly used in situations where distance, angle of view, and limited lighting make direct visual examination impossible, or where access is restricted due to time, financial constraints, or atmospheric hazards. RVI/RDVI is commonly used to assess the “health” and operability of fixed and portable assets as predictive maintenance or regularly scheduled maintenance tool. RVI/RDVI improves inspection coverage, repeatability, and data comparison. The “remote” portion of RVI/RDVI refers to the operator not entering the inspection area due to physical size constraints or potential safety issues associated with the inspection environment.

Visual Inspection Solutions 

The borescopes and visual inspection equipment are portable, intelligent solutions that meet the demands of modern industrial inspections when inspecting difficult-to-access areas. A host of advanced, intuitive features and a wide range of borescope, videoscope, and fiberscope lengths, diameters, and viewing options make our remote visual inspection solutions versatile for many applications.


  • Aircraft engines (turbofan, turbojet, turboshaft).
  • Aircraft fuselage.
  • Turbines for power generation (steam and gas).
  • Process piping (oil and gas, pharmaceutical, food preparation).
  • Nuclear Power Stations – contaminated areas.
  • Any areas where it is to dangerous, small or costly to view directly.


  • Less mechanical disassembly to access subject areas.
  • Reduced NDT costs over other forms of testing.
  • Reduced shut down times and faster reinstatement of equipment.
  • Fewer safety constraints over manual inspection methods.
  • Faster, accurate monitoring of equipment condition during life cycles.
  • Better assessment of condition and timing prior to critical maintenance.
  • Faster identification, location and isolation of faults.
