The visual inspection is at the base of each quality production, but also of each type of inspection and maintenance. It is not always possible to perform this type of checks, as the part to be inspected can be internal or be located in places that are not directly visible and poorly lit.

There are measuring instruments, such as industrial video inspection systems, which allow reaching points that are difficult to detect by human eye and to record videos or take photos that can be analyzed in a second step.

Industrial video inspection systems can be equipped with an adjustable head, so that the operator has the possibility to direct the sensor following the curvature of the piece.
