Swann PRO-781 Manual page 3

Regardless of all the tweaking of the lens and image processing you do, there are
a few immutable things that are true for all cameras, CCTV or otherwise.
• The closer the camera is to what you want to see, the more detail
you're going to get. You can make some alteration by tweaking the zoom,
but there's no substitute for proximity.
• Areas with varied lighting conditions are hard to view completely,
with any camera. If the bright bits are exposed correctly, then the shadows
will "black out". If the shadowy areas are exposed correctly, then the bright
bits will overexpose and "white out". Aiming the camera at an evenly lit area
will always give the best results.
• That "image enhancement" stuff that they do on CSI or 24 is all lies. You
can't zoom in indefinitely on a video image. Licence plates are only readable
from a few meters (a dozen or so feet) away. If someone's head is represented
by three pixels, that's it. Sorry. This is technology, not magic. This is a great
CCTV camera, but it's still just a video camera - it can't see that much better
than you can! Still, it does make for good television.
• To access the zoom and focus, remove the dome cover. To open the dome
cover, use the included star-key tool.
• Use a small flat-blade screwdriver to turn the now exposed control rods. The
zoom is located on the top left, and focus on the lower right.
• Be sure to securely replace the dome cover after adjusting the positioning of
the camera, or the zoom and focus: otherwise the camera will no longer be
weather-proof.
