My webcam is not detected

If Screencastify is unable to detect your webcam, the extension will not be able to capture your webcam or embed your webcam within your recordings.

Here are a few steps you can take to resolve the issue.

Step 1: Test your webcam at

If you are able to view your webcam, Google Chrome can access your camera. If not, there is something blocking Chrome's access.

Step 2: Restart Chrome

It's possible for Chrome to lose access to your webcam. This can often be fixed by simply restarting Chrome.

Step 3: Restart your computer

Sometimes software/patches installed on your device can disrupt webcam access until a restart.
