An inspection camera, often called a borescope or endoscope, is a specialized optical tool designed to provide a high-resolution view into cramped, dark, or inaccessible spaces. It consists of a small, LED-illuminated lens mounted on the tip of a flexible or semi-rigid cable, which feeds live video back to a handheld monitor or a connected smartphone. These devices are essential for “non-destructive” diagnostics, allowing professionals to inspect the internals of car engines, plumbing lines, or electrical conduits behind drywall without having to tear apart the structure first.
