An inspection camera, or borescope, is an instrument that functions like a camera, microscope, or telescope: it enables you to observe areas that are too cramped, too far away, or entirely out of reach. Some of the cameras provided can have up to 5 Meters of cable length! It is called a camera because there is a very small High Resolution camera at the end of the Scope tip which you can use to take photos or video, and then store the captures in a SD card provided with the Videoscope - Inspection Camera! If you are need to inspect oil pipelines or gas tanks, make sure your inspection camera is hazardous-environment rated. Most inspection cameras/borescopes are not safe for use in combustible environments!
