When repairing a car, pipelines and other structures and mechanisms, there is a need to visually inspect the condition of hard-to-reach places. Using a USB endoscope allows you to get a high-quality image on the screen of your smartphone. To use it you need to install a special application and support OTG function. The package includes a 16.4-foot-long USB endoscope in a dust and water resistant shell, with a 0.3 megapixel camera and six LED light sources.
