Focus

Focus, also known as Remote Focus, is applicable to Network Cameras that are equipped with stepping motor lens. The automated focus adjustment function eliminates the needs to physically adjust camera focus. In an outdoor deployment consisting of a large number of cameras, the auto focus function can be very helpful when these cameras become out of focus after days or weeks of operation. And that can easily result from the effects of natural forces, e.g., shrink and expand due to a wide range of operating temperatures and the vibration caused by wind.

adjust the zoom ratio. 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 auto 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 Perform auto focus button, and wait for the scan to complete.

5.After a short while, 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 "+" 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.
