How to adjust the focal length of computer camera?

The camera in the computer is fixed focus, so there is no way to adjust the distance. If you really want to adjust, you can only remove the camera. There are COMS imaging things in it, so the distance between the two lenses has been adjusted. Because you are not a professional, it is recommended not to open it.

If an external camera is installed on the computer, and it can adjust the focal length, you can adjust the distance to see the instructions, and some cameras can twist in a prominent position to adjust the focal length.

The camera on the computer can be turned on and off. If you don't use it at ordinary times, it's best to turn it off or cover it with something for safety reasons. If you want to open it, the operation method is as follows:

Find and click "Device Management" in the control panel of the computer, click "Mirror Device" in the new page, then click the item that appears, select the "Driver" tab in the new dialog box, find the "Enable" button and click.
