Using the camera in or around water.
This waterproof camera is supplied with a UL approved 12 VDC power supply. If the camera is to be used in an area that is required by UL and electrical code to use a GFI (ground fault interrupter), the 12 VDC adapter MUST be connected to a GFI outlet. The power supply is NOT waterproof and should be mounted indoors. Typical areas that require a GFI approved outlets are any outdoor applications, garage, bathroom or kitchen locations, or any other area that may have water or moisture present. ADDITIONALLY all system components (monitor, VCR, power supply, etc or other equipment) that may be connected to the camera, directly or indirectly, must also have GFI protection. CCTV monitors or TVs used to view the camera must be fully protected from any possible moisture contamination. Be absolutely positive before connecting any 120 VAC monitor, recording device, etc. that the device(s) does not have stray electrical leakage that can cause a dangerous or deadly electrical shock hazard once the camera comes near water. Contact a licensed electrician for further information on requirements for GFI usage. All non-waterproof system components must be located indoors with appropriate electrical shock precautions adhered to.
The same precautions apply when using the camera around earth grounded items. Such as metallic pipes, plates or equipment that may be in contact with earth or soil or water.

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.
