A camera system for inspection, also called a borescope or endoscope, is utilized for visually examining hard-to-reach areas. It includes a camera connected to a tube - either flexible or rigid - that is placed into the desired area. The camera sends live video or pictures to a screen, enabling the user to see and identify problems in inaccessible areas.
