Used to inspect many hard to reach locations including the back of your own head, it can help to find skin moles that you would not be able to see in any other way.

It may be useful to attach an inspection camera to a 'plumbers snake' or a garden hose that can be maneuvered to the location you need to inspect.
Inspection cameras are very small TV cameras with headlights.
Attaching the camera one foot behind of the tip of the snake will allow you to view your progress and the tip of the snake will take the brunt of the force banging into obstacles and 90 degree elbows.
The first foot of the snake can be used to help steer your camera in the direction of interest.
The camera will tell you when the snake is going the correct direction at a 'Y' or 'T' joint.

Attaching the camera to the end of a telescoping roller paint pole can help position your camera either up down or sideways.
