Swann PRO-781 Manual page 9

You probably need to adjust the focus (the knob on the right). This is simply a
matter of removing the dome cover, and turning the control knob one way until
you find the best focus point or it won't turn any more. Detailed instructions for
setting the focus can be found on pages 4 and 5. Then, turn it back the other way.
If there is no "sweet spot" then this indicates one of two things.
1. Your lens might be dirty. Clean the front of it with a dedicated lens cleaning
cloth (available at any camera store). Avoid using solvents or cleaning
chemicals, as these can leave a residue.
2. You might be trying to focus on something outside the "depth of field" -
objects need to be at least a certain distance from the camera for you to be
able to focus on them. Typically, this will be only a few feet (about 1m) but
this distance can increase dramatically if the lens is zoomed in, or in low light
conditions.
3. Be sure to replace the dome cover securely once you've set the focus!
We're constantly on the lookout for ways to incorporate more features and more
advanced technologies into our products. So here's one we're excited about:
the PRO-781 features an On-Screen Display (OSD) that you can control with the
included control unit.
As this is a new, powerful feature, we couldn't possibly fit the full explanation of
everything it can do into this booklet. So, we've created an online guide you can
access at:
Of course, you don't have to use this feature at all. The PRO-781 will work
perfectly well if you never even connect the controller – it'll adjust all of its settings
automatically.
Everything looks blurry/soft.
