Webcam Folder Search
Capture a live webcam snapshot as the reference face and search a server-side image folder
Webcam Folder Search works identically to Folder Person Search, except the reference face is captured live from the device webcam rather than uploaded as a file. This is useful in on-site scenarios where the operator wants to search for a person standing in front of them without needing a stored photo.
How It Works
- Camera initialises automatically on page load.
- Position the subject — they should face the camera directly in good lighting.
- Click Capture — the system takes a snapshot and extracts the face embedding from it.
- Select a server folder — choose the image archive to search.
- Run the search — the captured embedding is compared against all faces in the folder, returning ranked matches.
When to Use This
| Scenario | Recommended Tool |
|---|---|
| You have a photo of the person | Folder Person Search |
| The person is physically present | Webcam Folder Search |
| You need real-time tracking across feeds | Cross-Camera Tracker |
Capture Tips
- Ensure the face is centred in the webcam preview and well-lit.
- Avoid backlighting — the subject should face the light source, not have it behind them.
- Only one face should be visible in the capture frame to avoid ambiguity.
- If the captured snapshot is not ideal, click Retake to try again before running the search.
Technical Details
The captured frame is encoded as a JPEG blob and submitted to the same backend search endpoint as Folder Person Search. The similarity threshold, server folder selection, and result ranking logic are identical between the two tools. See the Folder Person Search page for threshold configuration details.
