Below is the procedure to perform
the remote Zoom and One-touch
Focus function:
1. Use the
Zoom
slide bar to find
an optimal view of the area of
interest where you want to adjust
its focus. Click and drag the
double-triangle pointer to rapidly
adjust the zoom ratio. And use
the "W(Wide)" or "T(Tele)" button,
"<" or ">" button to finetune the
zoom if necessary. The
Focus
pointer moves with the Zoom
pointer correspondingly.
2. Select from the bottom of the
screen whether you want to
perform focus adjustment on the
Full view
or within a
Custom
focus window. You can create
a custom window and click and
drag the window to a desired
position on screen.
3. In theory, best results of the focus
scan can be acquired when the
camera's iris is fully open.
Before One Touch Focus, click iris
Open
button, and wait 5 seconds until an iris actually opens.
4. Click on the Focus
Start
button or
Full-range scan
button, and wait for the scan to complete. When
selected
Full-range scan
, a full range scan through the camera's entire focal length can take about
80 seconds. When selected
Start
, the focus scan will only go through the length where optimal focus
may occur, and that takes about 25 seconds.
5. After a short while, the clearest image obtained should be displayed . Then, click on the Iris "Enable"
button. Use the "N(Near)", or "F(Far)", button, "<" or ">" button to fine tune the focus if you are not
satisfied with the results.
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.
● One-Touch Focus is sometimes not possible when shooting through a glass pane, a flat object such as
a wall and moving object. Achieve focusing of these objects by manual focusing.
● One-Touch Focus is sometimes disabled due to noise in low-light intensity. Then adjust focusing by
manual.
● One-Touch Focus is sometimes not possible when the object is dark and camera sensitivity is not low
enough. Then adjust focusing by manual.
● One-touch focus will stop on the way, if other camera operations are practiced during operation. Do
not touch until the "Start" button is displayed again.
