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 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.Click to select the Full-range scan and/or the Fully-open iris checkboxes. When selected, a full- range scan through the camera's entire focal length can take about 80 seconds. If not, the One-Touch focus scan will only go through the length where optimal focus may occur, and that takes about 12 seconds. In theory, best results of the auto scan can be acquired when the camera's iris is fully open. The iris fully open checkbox is selected by default.

4.Click on the START button, and wait for the scan to complete.

5.After a short time, the clearest image obtained should be displayed and the optimal focus range is indicated by the densest color area on the color bar. Use the "F(Far)" or "N(Near)" 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.

NOTE

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.

Auto focusing is sometimes not possible when the object is dark and camera sensitivity is not low enough. Then adjust focusing by manual.
