GeoVISION™ Borehole Video Systems

The GeoVISION Nano camera is the smallest diameter production borehole video inspection camera made today. The Nano camera is a mere 3/4 inch (2 cm) in diameter and is designed for use in boreholes as small as one inch (2.5 cm) in diameter and at depths up to 2000 feet (600 meters).

The Nano camera has standard NTSC resolution with an aspect ratio of 4:3. Illumination is provided by six high intensity white LEDs. The Nano camera is rated for use up to 1,000 psi and can be used with Light-Duty, Heavy-Duty and Deluxe winches.

The Nano camera can also be used with the Nano Rotating Mirror to allow a side scan of the bore wall. The Nano Rotating Mirror can be set to rotate continuously or to rotate approximately 20°, pause for a few seconds and then continue rotating. The pause in rotation allows maximum resolution for recording the video image.

The GeoVISION™ Pan-Tilt Control is designed to rotate and tilt Standard Stainless Steel and Standard Plastic cameras. Using a Pan-Tilt Control, these cameras can be rotated 360-degrees and can tilt from looking straight down, to looking back up the bore. Camera manipulation is controlled using the joystick on a Deluxe winch.

The Pan-Tilt Control also allows the Standard Stainless Steel camera to be switched into Center Exposure mode. In Center Exposure mode, the camera sets the exposure based only on the center of the image. This is useful when looking through a small opening into a larger void.

The Pan-Tilt Control can be operated to depths of 2,000 feet (600 meters) and must be used with a Deluxe winch and either a Standard Stainless Steel or Standard Plastic camera.

The Standard Stainless Steel camera is the workhorse of the GeoVISIONTM line of cameras. Standard Stainless Steel cameras come in both color and black & white. These cameras are extremely rugged and designed for use in two-inch (5 cm) and larger diameter bores, up to 2,000 feet (600 meters) deep. They can be used alone, or mounted on a Pan-Tilt Control for easy joystick manipulation.

The Standard Stainless Steel cameras have standard NTSC resolution with an aspect ratio of 4:3. Illumination is provided by eight high intensity white LEDs. The LEDs can be turned on or off unless the camera is used with a Light-Duty winch, in which case the LEDs are always on. Standard Stainless Steel cameras are rated for use up to 1,000 psi and can be used with Light-Duty, Heavy-Duty and Deluxe winches.

Standard Stainless Steel cameras have a mounting screw near the front of the camera for attaching accessories such as a side-looking mirror or a ball compass. In shallow wells, these cameras can be connected to a pipe-string providing an economical way to pan and tilt the camera from the surface.

When mounted on a Pan-Tilt Control, the Color Standard Stainless Steel camera has the added ability to adjust the exposure to the center of the screen rather than the entire screen. This allows the camera to look through holes in the bore wall and properly expose what lies beyond.

The GeoVISION Standard Plastic Color and Black & White cameras are a great economical choice when the conditions are right. Standard Plastic cameras are designed for use in two-inch (5 cm) and larger diameter bores, up to 1,000 feet (300 meters) deep. These cameras are more sensitive to heat than Standard Stainless Steel cameras, and cannot be stored or operated in environments hotter than 110° F (43° C). They can be used alone, or mounted on a Pan-Tilt Control for easy joystick manipulation.

The Standard Plastic cameras have standard NTSC resolution with an aspect ratio of 4:3. Illumination is provided by eight high intensity white LEDs. Standard Plastic cameras are rated for use up to 500 psi and can be used with Light-Duty, Heavy-Duty and Deluxe winches.
