2) Permission & troubleshooting help

If the camera or mic is blocked, use this checklist. Most issues are fixed in under a minute.

Fast fix (1 minute)

Try these in order:

Click the padlock / camera icon by the address bar → set Camera/Microphone to Allow → reload.
Close other apps using the camera/mic (Teams/Zoom/Meet) and try again.
If it says blocked by an extension, use the section below (Incognito test + disable extensions).

Quick permission checklist (works for most browsers)

Look for a camera/mic icon near the address bar and allow access for this site.
Reload the page after allowing permissions.
Close other apps using the camera/mic (Teams, Zoom, browser tabs).
On Windows/macOS, also check system privacy settings (camera/microphone allowed for your browser).
If you’re on a work device, a policy may block camera/mic—try a personal device to compare.

“Camera or microphone is blocked by an extension”

This usually means a browser add-on (privacy blocker, security tool, script blocker, parental controls) is overriding site permissions.

Step 1: Open an Incognito / InPrivate window and try again (many extensions are disabled there).
Step 2: If it works in Incognito, you’ve confirmed it’s an extension. Disable extensions one by one:
Chrome/Edge: ⋮ → Extensions → Manage Extensions
Step 3: Re-enable extensions one at a time until it breaks again — the last one switched on is the culprit.
Step 4: Keep it disabled for this site, or adjust its settings (allow camera/mic, whitelist ecomputerz.com).

FAQ

Short answers to the most common “why isn’t it working?” problems.

Does this tool record or upload my audio/video?

No. It only shows a local camera preview and microphone level meter in your browser. Nothing is uploaded.

Why are my device names blank?

Many browsers hide device labels until you grant permission at least once. Click “Start camera” or “Start mic”, allow access, then refresh devices.

Why does it say the device is “busy”?

Another app or tab is already using the camera or microphone (Teams, Zoom, Meet, etc.). Close them fully and try again.

Why can’t I choose a speaker/output device?

Some browsers don’t support output selection, or they restrict it for privacy reasons. Use your system output settings, or try Chrome/Edge on desktop.
