Endoscope cameras or video endoscopes have long, flexible cables to reach almost any inaccessible point in cavities, holes and dark niches. They are equipped with a memory card, monitor, rechargeable batteries and further accessories, and they are mobile and versatile. For example, brittle or defective outlet pipes can be recorded with a waterproof endoscope. The images are either saved on a storage medium or transferred directly onto other devices, such as smartphones or tablets. Video endoscopes are practical everyday tools for vehicle repair, in workshops and in the healthcare sector, and they are used to check complex devices such as air conditioning systems.
