down-hole video camera services

down-hole video camera services with digital video and audio recording capabilities. The camera has both down and side viewing lenses with independent light sources. The probe and attaching hardware are fully sealed stainless steel and can be submerged in ground water and acid mine drainage. The camera orientation can be determined to locate true positions of features observed in the borehole. A custom centralizing assembly allows for viewing in holes of any inclination. SGS also has a full video editing capability to convert the video into CD or DVD viewing formats.
