Webcam Test

Webcam Test requests camera permission and shows a live preview stream so you confirm the correct device, framing, and lighting before joining a video call.

It runs entirely in-browser—no recording is sent to Apex Toolz servers when you use the local preview workflow.

Interview candidates discover dead webcams five minutes before HR calls—quick test avoids panic.

IT verifies USB camera vs built-in laptop cam selection after dock reconnect.

• Pre-call check before Zoom or Google Meet
• Verify new external webcam after plug-in
• Troubleshoot black screen camera permissions on macOS
• Confirm browser has camera access after OS privacy reset
• Framing check for webinar presenter setup

1. 1Click allow when the browser prompts for camera permission.
2. 2Select correct camera from dropdown if multiple devices appear.
3. 3Verify live preview shows expected room and lighting.

• Close other apps using the camera—only one app may lock the device on some OS builds.
• Browser permission denied? Check OS-level camera privacy settings for Chrome or Safari.
• External webcam flicker may be USB hub power—plug directly into laptop.
• Internet Speed Test when video lags despite working camera hardware.

• Preview quality depends on browser codec support—not identical to Zoom encoding.
• Does not test virtual camera software like OBS unless selected as device.
• Common mistake — forgetting to stop stream: camera LED stays on and blocks other apps.
