Camera or Microphone Not Working in Video Chat
If the camera will not turn on, the cause is nearly always one of three things: the browser is still remembering a permission you denied, another program already has the camera open, or the browser picked the wrong device. All three take under a minute to fix.

Nothing kills a video chat faster than a black square where your face should be. The good news is that this is almost never a hardware fault and almost never the website. It is a permission that is stuck, a program that will not let go, or a dropdown pointing at the wrong camera.
Work through this in order. Most people are fixed by the end of the second heading.
First: the thirty-second check
- Reload the page. Not a new tab — an actual reload. Permission changes do not apply to a page that is already open.
- Look at the address bar. A crossed-out camera icon there means the browser is blocking it, and no amount of clicking start will change that.
- Close anything else that uses the camera. Meeting apps, recorders, and virtual-camera tools keep the device even when they are minimised to the tray.
- Check the physical shutter. Laptops have had sliding privacy covers for years now, and they are easy to forget about.
Chrome and Edge
Click the icon at the left end of the address bar — a slider, a tune icon, or a padlock depending on the version. You will get a small panel with Camera and Microphone in it. Set both to allow, then reload.
If the switches are greyed out or nothing happens, the block is one level higher, at the operating system:
- Windows: Settings → Privacy & security → Camera. Turn on camera access, then make sure desktop apps are allowed. Repeat under Microphone.
- macOS: System Settings → Privacy & Security → Camera, and tick your browser. macOS requires the browser to be restarted after this — it will usually offer to do it for you.
Safari, including iPhone and iPad
Safari asks once per site and then remembers, which is why a rushed "Don't Allow" is so hard to undo from inside the page.
- Mac: Safari → Settings → Websites → Camera, find the site in the list, set it to Allow. Same again under Microphone.
- iPhone and iPad: tap the aA icon in the address bar → Website Settings → Camera → Allow. If the site is not listed there, check Settings → Safari → Camera and make sure it is not set to Deny globally.
One iOS quirk worth knowing: a video call will not start while the phone is in Low Power Mode with a background download running. If everything above looks correct and the camera still stalls, that is usually why.
Firefox
Firefox is the one browser that will silently keep a "block" you set by accident. Click the padlock in the address bar, find the blocked permission, and press the small ✕ next to it to clear the rule entirely — then reload and answer the prompt again. Setting it to allow without clearing it first does not always take effect.
"Camera in use by another application"
This message means exactly what it says, and the culprit is usually not visible. On Windows, check the system tray for meeting software that closed its window but not its process. On macOS, check the menu bar. If you cannot find it, the reliable fix is to quit the browser completely — not just the tab — and open it again.
Virtual camera tools deserve their own mention. If you have ever installed one for streaming, it may be registered as your default camera. The browser will happily use it, and the person on the other side will see whatever it is pointed at, which may be nothing at all.
Right camera, wrong picture
If the camera light is on but the other side sees a black frame, the browser has the wrong device selected. Open the same site permission panel you used above — most browsers list every camera and microphone attached, including ones inside monitors and docking stations. Pick the one you actually want and reload. Laptops with an external screen get this wrong constantly.
The microphone is a separate permission
Camera and microphone are granted independently, and it is entirely possible to have working video and silent audio. If the other person can see you but not hear you, go back to the same panel and check the microphone line specifically — then check that your system input is not set to a device that is not plugged in, which is the usual cause on desktops.
What is never the answer
No browser video chat needs a driver, a codec, a plugin, or an extension to reach your webcam. Modern browsers do this natively and have done for a decade. If a page tells you otherwise and offers a download, close it — that is the oldest trick on this part of the internet, and it is not one we play. The same goes for anything that wants your camera fixed by installing a "system optimiser".
Still nothing
Two last checks before assuming the hardware is dead. Open your operating system's own camera app: if it is black there too, the problem is the device, not the browser. And try a private window — an extension blocking media is common enough that this is worth ten seconds.
If your camera works everywhere else and still not here, tell us via the contact page and include your browser and operating system version. That is genuinely useful to us; a report that says only "camera broken" is not.
Short version: reload, clear the site permission rather than just toggling it, close whatever else has the camera, and check which device the browser selected. That is four fixes covering nearly every case.
Once the camera is behaving, how random video chat works covers what happens after you press start, and what happens to your video call covers what is and is not kept once the camera is on.
