Honest About the Boundary

Camera Access & Privacy Monitor

No web page — this one included — can see other browser tabs, other applications, or background processes. That is a deliberate browser security protection, not a gap. What this genuinely does: watches this page's own camera permission state live for changes, and walks you through confirming your camera's hardware LED actually works — the most trustworthy signal for "is my camera active" that genuinely exists, seen with your own eyes rather than reported by any page.

This watches for changes automatically — no action needed. It updates live if you revoke or grant permission from your browser's own settings while this page is open.

Hardware Check

Confirm Your Camera's Indicator LED

With the camera running above, look at your camera's physical indicator light right now.

Notes

What a web page can and cannot see

QuestionAnswer
Can this page see its own camera state?Yes
Can it see other tabs using the camera?No
Can it see other applications using the camera?No
Can it see background system processes?No

This is a deliberate browser security boundary, true for every website, not a limitation specific to this tool.

Checking your OS directly

Windows 10/11Settings → Privacy & Security → Camera shows recent app access, and a system tray indicator appears while any app uses the camera.
macOSAn indicator light appears next to the camera when active, and recent macOS versions show a menu-bar dot you can click for which app has access.

Step-by-Step

How to Use This Tool

  1. Load the page — it immediately starts watching this page's own camera permission state.
  2. Click "Start Camera" and allow access when prompted.
  3. Look at your camera's physical LED right now, with the stream running.
  4. Click "My LED Is Lit" to confirm — this builds trust in that hardware signal for future reference, independent of any software.

Common Questions

Frequently Asked Questions

Can this tell me if another app or tab is secretly using my camera?
No, and any tool claiming to is not being honest with you. Browser security is specifically designed so a web page cannot see other tabs, other applications, or background processes — that isolation is a core protection. This reports what a page genuinely can see: its own permission state, plus a guided check of your camera's hardware LED.
Why is the camera's LED light trustworthy?
On the large majority of modern webcams, that light is wired directly to the sensor's power rail specifically so software cannot light it up or suppress it independently of the sensor actually being active. If it is lit and you did not expect any app to be using the camera, that is real, meaningful information.
How do I actually see which app is using my camera?
That information only exists at the OS level. Windows 10/11 show a camera-in-use indicator and a history under Settings → Privacy → Camera. macOS shows an indicator light plus, in recent versions, a menu-bar dot you can click to see which app currently has access.
How is this different from the Camera Block Detector?
The Camera Block Detector diagnoses why a camera ISN'T working right now, across permission, driver, and hardware causes. This tool is about staying aware of camera access WHILE it's working — live permission-state monitoring plus confirming your hardware LED, rather than diagnosing a fault.
Does watching the permission state use any extra resources?
No — it uses the standard Permissions API to listen for change events, which is a lightweight, event-driven check rather than continuous polling.
