Overview

The Nano camera has standard NTSC resolution with an aspect ratio of 4:3.  Illumination is provided by six high intensity white LEDs.   The Nano camera is rated for use up to 1,000 psi and can be used with Light-Duty, Heavy-Duty and Deluxe winches. 

The Nano camera can also be used with the Nano Rotating Mirror to allow a side scan of the bore wall.  The Nano Rotating Mirror can be set to rotate continuously or to rotate approximately 20°, pause for a few seconds and then continue rotating.  The pause in rotation allows maximum resolution for recording the video image
