Notes
* The micro camera uses a ring light with nine high brightness LED’s, and either a regular or motorized mirror with three out-front, high-brightness LED’s. Some of these ratings will be affected by which combination of lights is used.
Wide angle lens advantages
and disadvantages
2.45 mm wide angle lens is very good at close up images. Distant images, 3 feet and greater, appear very small.
2.9 mm wide angle lens is good at close up images. Distant images, 3 feet and greater, appear small.
3.6 mm lens is best at images from 5 inches to infinity. Distant images appear larger with this lens than they do with other lenses. This is a special order lens available with all GeoVISION cameras.
The 3.6 mm lens is recommended for mines, caves, and very large boreholes.
Special features of GeoVISION
cameras
The GeoVISION Standard stainless steel cameras have camera
lights on/off circuitry for use with supplemental lights for improved
visibility in poor quality water.
All GeoVISION cameras are interchangeable when used with the GeoVISION™ Deluxe system
All GeoVISION cameras have over voltage and heat protection.
The GeoVISION stainless steel cameras have recessed attachment points allowing the camera to fit in smaller boreholes.
The GeoVISION black and white cameras have a lux rating of .01 at F2. This ultra low light feature means that even in very low light these cameras will produce a good image where other borehole cameras under the same lighting conditions will not have a usable image
Recommendations for large
boreholes, mines, caves, tunnels, tanks, pipes, and other voids
Any combination of these items listed below will help get a better image at greater distances
Black and white ultra low light camera
Motorized pan and tilt option for depths to 2000 feet or the manual pan and tilt that is standard with all JR and Standard cameras for use at depths less than 200 feet. The 200 foot depth is a mater of personal choice. The manual system becomes more difficult to operate at greater depths.
