This post will explain the way to disable your webcam on Windows and Linux, so:
- On the OS level, prevent you from turning on the webcam by mistake, and live-stream your footage of
having a meal lying on the bed playing games (NSFW)
- Prevent certain online lecturing software from secretly turning on the webcam.
Win+R combination key to open the Run window, type
devmgmt.msc and enter to open the Device Manager. Your camera will be in
Image Acquisition Devices category, right-click on it to disable it.
(The following picture is taken from a Simplified Chinese Windows XP, but the procedure and icons should be similar for Windows 7 and 10.)
When you need to use the camera, come back to re-enable it, and then close and reopen your browser or online lecturing software.
# First, close any software that uses your webcam,
When you need your webcam, run
sudo modprobe -v uvcvideo to load the drivers. After you're done, run
sudo modprobe -rv uvcvideo to unload it. After the load/unload, you simply need to close and reopen your browser or online lecturing software.
