Geovista Well & Borehole Camera Systems

Geovista supply a range of colour borehole cameras featuring high resolution CCD sensors. All cameras come with white LED integral lighting and optional external lighting for larger borehole diameters.

Cameras are controlled from either a dedicated surface panel with a 6" video monitor or a PC based display unit that allow for in-situ video image capture and reporting. The PC based display unit can also be used for borehole logging
applications.

An integrated rack mounted VHS VCR is optionally available

An option to measure and display image orientation and borehole inclination on the video monitor is available with the swiveling head camera . Data can be transferred to a PC via the RS232 port for further processing if required.
