Hey Eimantas,

You can use the preview method, which is a part of MATLAB Support package for USB Webcam, to see the live output from the webcam device of your choice passed as a parameter to it. Refer the documentation below for more details:

However, if you want to create a custom UI to display the live output, then the following MATLAB Answer is a good starting point:
