Matrix Drilling now has a water well inspection system which is equipped with two cameras in a single housing, each with a wide-angle lens, for allowing you to view down-hole and side-view images in water wells or open boreholes.
Low-light CCD sensors allow the cameras to detect images with minimal lighting power. In-built LEDs provide lighting to enable colour images. A single-conductor, armoured, Kevlar®-re-inforced, coaxial cable links the camera to the video output.
