Screen Share allows you to share Android screen or camera in browser to multi-users, but doesn't require user to install plug-in or client software. It doesn't require root permission either. Users can not only directly connect to your device to see the screen or camera, but also can connect to your device through a dedicated server.
Note: To share screen, Android 5.0 or later is required. To share camera, Android 2.3 or above is required.
