HAM2 West door analog camera gave intermittant images, which appeard to be related to the power cable, which was not resolved by repositioning the cable.  I removed the camera and the camera can, and covered the viewport with a yellow cover.   The viewport is called as HAM2 viewport A1F1,  as it is identified in T1200240 (AKA West door, top viewport on the North side).   Filiberto is looking at the cable, and initial assessment is that the cable is good.  I'll be checking the camera as well.
