Videoscopes, also known as borescopes or inspection cameras, are high-tech tools used to see inside tight spaces or areas inaccessible to the naked eye. They're like tiny "eyes" on a flexible probe, offering real-time visual inspection in:

• Confined spaces: Inside machinery, engines, pipes, walls, or even human cavities.
  

• Hazardous environments: For remote inspection without putting yourself in danger.
  

• Underwater areas: Some videoscopes are waterproof for underwater exploration.
