This page demonstrates how to test for webcam availability, activate it with user permission, perform a webcam or screen capture, save the capture to a file on the server, and display the saved image. Use the menu above to switch between device information, webcam capture, and screen capture sections. All actions require explicit user consent via browser prompts.
Security Notes: This code relies on browser APIs that enforce user permissions. Always serve over HTTPS. Captures are saved server-side in a secure directory and displayed using absolute URLs. Ensure the 'uploads' directory has proper permissions (e.g., 0755) and is readable by the web server but not publicly indexable. Device information is collected client-side for display only. For educational purposes only; do not use for unauthorized access.
