Directly below each "camera" image, you'll see a bar containing a slider control, a counter and a percent figure. Using the slider as a rough adjustment and the counter arrows and digits to fine-tune, the image will become clearer as the figure at the right approaches 100%.Exactly how is that done... "Explain it as if you were talking to a child." (from Galaxy Quest)Not much to be done about short and looped, but you can get a reasonably sharp image if you dial the signal in correctly. Other than the intermittent corridor picture, I'm not aware of anything else having appeared there.
