Starting the camera
1
Click Start Camera
On the main screen, click the Start Camera button. If this is your first time, your browser will ask for camera permission — click Allow.
2
Point at a vehicle
Hold your device so the license plate is visible in frame. Scanning begins automatically as soon as the camera feed appears.

Wait for detection
The app runs continuously in the background. When it finds a plate, it draws a green box around it and saves the result to your history.
Camera access requires a secure context. The app must be opened over HTTPS or on localhost. If you see a permission error, check that the URL starts with
https://.Camera controls during scanning
Once the camera is active, a row of controls appears at the bottom of the preview area.Auto-stop behavior
By default, the camera stops automatically after it confirms a plate. This saves battery and avoids scanning the same vehicle repeatedly.- The camera stops after 3 seconds of continuous plate detection.
- If the detection has a mean OCR confidence of 0.8 or higher, the camera stops after just 1 second.
When Skip duplicates is on, confirming a plate already in your history will not stop the camera — even in single-capture mode. The camera only stops for genuinely new plates. This lets you keep scanning in a busy area without being interrupted by vehicles you have already logged.
Live scanning indicator
While the camera is active, a small badge appears in the top-right corner of the preview:- Scanning (with a pulsing dot) — the app is actively processing frames and looking for plates.
- Live (with a steady dot) — the camera is on and ready, but no plate is being actively processed at that moment.
