Downhole Camera System

The Groundsearch colour borehole video camera system is supplied by GeoVISIONTM and has a maximum depth capacity of 600m. It allows high-quality, real-time video imaging and DVD recording of boreholes, shafts and voids. It uses a stainless steel, colour camera with a motorised mechanism to view downwards, pan 360 degrees and tilt 170 degrees. There is a compass to orientate features with respect to magnetic north in most open and PVC-cased bores/wells. 

The camera has eight built-in high brightness LEDs with a lights on and off circuit for that is used with eight adjustable, supplementary lights for better quality videos in poor quality water. 

 

 Factors that determine the quality of borehole images may include: 

• Water clarity. 

• Distance from the object. 

• Amount of light. 

• Location of light source in relation to the camera and the object. Suspended particles may reflect light directly into the camera lens – reduced by using supplementary light source. 

• Stability and location of the camera – controlled by the use of adjustable centralisers. 

• Angle of view between the camera and the object – flexible panning and tilting maximises viewing.
