The methodology of using the Resize Buttons at the upper left corner of the streaming
window is the same as that on the home page.
Focus window:
By default, the optimal focus is found on a full view window. You may designate a custom
window within your current eld of view to acquire the best focus out of it. However, you
can not place a focus window on a distant background, e.g., a hall way that stretches
away for 3 meters or farther. Doing so you will not benefit from the Focus window
function.
■
Full view: The focus tuning takes place by referring to the full view.
■
Custom: You can create a focus window and drag it to a place of interest in your view
window. Note that it is recommended to use this function only when you have a solid
object in your view window that is showing a consistent color or texture. This function will
not take effect if you set the focus window on a distant background.
You can try the Snapshot focus function (in Applications > Package management) when
applied in the above mentioned scenario.

be displayed and the optimal focus range achieved. Use the arrow marks on the sides
to ne-tune the focus if you are not satised with the results.
You may still need to use
the arrow marks to ne-tune the focus depending on the live image on your screen. “>”
means moving from wide to tele end; and “<” tele to wide.
