Frequently Asked Questions

Is my video or audio recorded?

No. Everything runs entirely locally in your browser using the browser's built-in WebRTC / MediaDevices API. No video frames, audio samples, screenshots, or any data are ever sent to any server. The Record feature saves clips directly to your device via a browser download. You can verify this by checking network activity in your browser's DevTools.

Why is the camera showing a black screen?

Make sure you clicked "Allow" when the browser asked for camera permission. Also check that no other application (Zoom, Teams, Google Meet, OBS, etc.) is currently using your camera, since most systems only allow one app at a time.

Can I test an external USB camera or microphone?

Yes. After granting permission the first time, the device dropdowns will populate with all connected cameras and microphones including USB and Bluetooth devices. Select the one you want and click Start Test again.

What does FPS mean and what is a good value?

FPS (Frames Per Second) measures how smoothly your camera captures video. Most webcams run at 25–30 FPS. Values below 15 FPS may cause choppy or laggy video on calls. High-end webcams support 60 FPS for extra-smooth video.

Which browsers are supported?

The latest versions of Chrome, Edge, Firefox, and Safari all work. Chrome and Edge provide the most complete results including full device labels. On iOS, Safari is required. On Android, Chrome works best.

What does the mirror toggle do?

Mirror mode flips your camera preview horizontally — like a real mirror or a selfie camera. This is purely a visual display effect and does not affect how you actually appear to others on a video call.

How do I record audio or video?

Start the test first to connect your devices. Then in the Microphone card, choose "Audio only" or "Video + Audio" and click Record. Click Stop when done — the clip will appear in the list below where you can play it back or download it. All recordings stay on your device.
