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.

Below is the procedure to perform the automated Zoom and 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. 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 30 to 80 seconds. If not, the auto focus scan will only go through the length where optimal focus may occur, and that takes about 15 to 20 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 achieved. Use the arrow marks on the sides 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.
