Test without installing software

ACC64 runs directly in a modern web browser. You do not need to create an account or install additional software.

Follow the instructions shown in the tool. If the issue is intermittent, repeat the test several times.

How to test a webcam properly

  1. Start the camera and select the correct device.
  2. Check resolution, measured FPS and the parameters exposed by the browser.
  3. Move your hand in front of the lens to judge smoothness and delay.
  4. Check facial sharpness, exposure and color in normal lighting.
  5. Take a snapshot and download it as PNG or JPG to inspect a full-resolution frame.

Permissions, drivers and browsers

If the camera does not start, open the padlock/site settings and set Camera to Allow. Close other apps that may be using it. On Windows check Settings → Privacy & security → Camera and Device Manager → Cameras. On macOS check Privacy & Security → Camera. In Chrome, Edge, Firefox and Safari verify that acc64.com is allowed to use the intended camera.

Teams, Zoom and Discord

Teams: Settings → Devices → Camera. Zoom: Settings → Video → Camera; review HD and auto-framing. Discord: User Settings → Voice & Video → Camera and run the preview. If ACC64 works but an app does not, close competing camera apps and reselect the device.

FPS, focus and lighting

About 30 FPS is normally enough for calls; 24 FPS should still look smooth. 15 FPS or less can come from low light, USB limits, heavy image processing or a high resolution. For soft focus, clean the lens, add front light and check autofocus. Strong backlight makes faces dark, so place the light in front or slightly to the side.

Frequently asked questions

What does this test check?

The test displays video from the selected camera and stream information so you can quickly verify basic camera and microphone operation.

Do I need to install anything?

No. The webcam test runs directly in a modern browser.

Does ACC64 save my test results?

No. The live camera feed and snapshots stay in your browser unless you choose to save a snapshot to your own device.

Does one bad reading mean the device is faulty?

Not by itself. Restart the camera and repeat the test. If the same freezing, low frame rate or image problem returns, check lighting, the USB connection and camera settings.

Why can results differ between browsers?

Camera permissions, supported resolutions and reported frame rates can differ between browsers. Try another browser if a feature is missing or the result looks unusual.
