Express Capture needs permission to access your camera and microphone. The first time you open Express Capture, your browser prompts you to allow access.
If you previously blocked access or your camera or microphone isn’t working, follow the instructions below to update the permissions in your supported desktop browser.

Test your camera and microphone
You can use the WebRTC test page to check whether your browser can access your camera and microphone:
- Go to the WebRTC constraints test.
- Click Get Media.
- Allow the browser to access your camera and microphone.
- Wait for the video streams to display.
If the streams don’t display, check the camera and microphone permissions in your browser and operating-system settings. Also make sure another application isn’t currently using the camera or microphone.
Passing the WebRTC test confirms that your browser can access the camera and microphone using WebRTC. It doesn’t confirm Express Capture support on an unsupported device, such as an iPhone or iPad.
