How to check your webcam and mic before a call

  1. Camera: press Start camera and allow access. The preview shows the resolution and frame rate your camera is actually delivering to the browser. If several cameras are connected, pick one from the list.
  2. Microphone: press Start microphone and talk at normal volume. Speech should push the level bar about halfway; a bar pinned at the end, or a verdict of “Too loud / clipping”, means it is too loud.
  3. Recording: press Record 5 seconds, then play it back to review a local recording; meeting apps, network conditions and remote playback can change what others hear, echo, hiss and distance from the mic become obvious.
  4. Speakers: play the left, right and stereo-sweep tones. If a tone comes from the wrong side, your headset may be reversed or set to mono.

What the numbers mean

Resolution and FPS

Most laptop webcams deliver 1280×720 (720p) at 30 frames per second. 1920×1080 (1080p) is sharper, but Zoom, Meet and Teams usually send 720p or less depending on your connection. A frame rate well below 24 FPS often means poor lighting, the camera lengthens exposure in the dark, or that another app is using the camera.

Microphone level

The meter estimates RMS signal level relative to full scale, not the loudest instantaneous peak. Comfortable speech peaks around the middle of the bar. If it barely moves, check the input device in your system settings, move closer, or raise the input gain.

Common fixes

  • "Permission denied": click the camera icon in the address bar and allow camera and microphone for this site, then reload.
  • Black preview: close Zoom, Teams or any other app that may be holding the camera, or check for a physical privacy shutter.
  • Wrong microphone: pick the correct device in the list, a headset and a laptop mic often both appear.
  • No sound from one side: check the headset is fully plugged in and that mono audio is turned off in accessibility settings.

Privacy

Camera and microphone streams stay on your device. Recordings exist only in this browser tab's memory and are discarded when you leave the page. Access stops as soon as you press Stop or close the tab.

If the camera or microphone is not detected

Work through the causes in order: the browser permission prompt (check the camera icon in the address bar), the operating system privacy setting for camera and microphone, another app holding the device (close video-call apps), and finally the cable or USB port. After changing permissions, try starting the device again; reload if the browser requires it.

What a good result looks like

A clear, evenly lit picture with no frozen frames, and a level meter that moves when you speak at normal volume without hitting the top constantly. If your voice only registers when you shout, raise the input level in your system sound settings rather than moving closer to the microphone.

Getting the best picture and sound in meetings

Lighting

Face a window or put a lamp behind your screen, slightly above eye level. Light from behind you turns your face into a silhouette and forces the camera to lower its frame rate. Raise the laptop so the lens is level with your eyes rather than looking up at you.

Bandwidth

Video calling services recommend roughly 1.5 to 3 Mbps upload for 720p and 1080p group video. If the internet step shows a slow or unstable connection, turn off HD video in the meeting app or close uploads and cloud backups running in the background.

Microphone gain

Set the input level so normal speech peaks around the middle of the meter, then leave the meeting app's automatic gain control on. Too much gain picks up keyboard noise and room echo; too little makes the app boost background hiss.

Fixing echo and feedback

Echo usually means your speakers are playing other people's voices back into your microphone. Use headphones, lower speaker volume, or move the microphone away from the speakers. If people hear themselves only when you are muted, the echo comes from another participant's setup, not yours.

Re-enabling blocked camera and microphone access

  • Windows 10 and 11: Settings, then Privacy & security, then Camera (and Microphone). Turn on access for apps and for desktop apps, including your browser.
  • macOS: System Settings, then Privacy & Security, then Camera (and Microphone). Enable your browser, then quit and reopen it.
  • iPhone and iPad: Settings, then Safari, then Camera and Microphone, and set them to Ask or Allow.
  • Android: long-press the browser icon, open App info, then Permissions, and allow Camera and Microphone.

Frequently asked questions

How do I check my webcam and mic before a Zoom call?
Open this page, press Start camera to confirm the preview, then Start microphone and speak, the level bar should move. Record a 5-second clip and play it back. The whole check takes under a minute and needs no download.
Why does my webcam show low FPS?
Low light is the most common cause: the camera slows down to collect more light. Add front lighting, close other apps that use the camera, and plug a USB webcam directly into the computer rather than a hub.
Can I test left and right speakers separately?
Yes. The speaker test plays a tone through only the left channel, only the right channel, and a sweep that moves from left to right, so you can spot a dead or reversed side.
Is my video or audio uploaded?
No. Everything runs in your browser. The recording stays in the tab's memory and is deleted when you close or leave the page.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari on Windows, macOS, Linux, ChromeOS, Android and iOS. The page must be opened over HTTPS for the browser to allow camera and mic access.
Why does the browser not list my device names?
Browsers hide device names until you grant permission. Start the camera or microphone once and the full device list appears.
Why does my Bluetooth headset sound worse when the mic is on?
Many Bluetooth headsets switch to a lower-quality hands-free profile when their microphone is active, which reduces sound quality for both listening and speaking. A wired headset or a separate USB microphone avoids this.
Does the test work with USB microphones and audio interfaces?
Yes. Any input device your operating system recognises appears in the microphone list once you grant permission. Choose it there and check the level meter.
Why does my video stutter with a virtual background?
Background blur and replacement are processed by your computer's processor or graphics chip. On older laptops this lowers the frame rate, so turn the effect off if the camera test shows a good FPS but meetings look choppy.
