The GeoVISIONTM Dual-Scan camera is Allegheny Instruments most advanced camera ever. It has three independently controlled banks of high intensity LED lights and the ability to rotate more than 360°. The Dual-Scan's state of the art video modules provide unparalleled video images in bores as small as 1-1/2" (4 cm) in diameter and up to 2,000 feet (600 meters) deep.
The Dual-Scan camera is actually two cameras in one. One camera continually looks down while the second camera scans the bore wall. The two cameras can be rotated from the surface using a joystick; this feature provides an uninterrupted 360° pan of both cameras simultaneously.
The Dual-Scan camera has standard NTSC resolution with an aspect ratio of 4:3. Illumination is provided by three banks of high intensity white LEDs which can be turned on or off from the surface. The Dual-Scan camera is rated for use up to 1,000 psi and can be used with the Deluxe winch.
