Hi Gustavo,

First, the Webcam must have a twain driver to work with TScanner.

You can get the images programatically without displaying them just using TScanner. See the Demo.Dpr project, but just don't load the received image in a visual component. If you are capturing from two devices, you might need to destroy and create a new scanner for the second capture. Not that only one TScanner object may be created at a time.

To choose the scanner without display the user interface see TScanner.Scanners and ScannerIndex property.

Best regards,
