If by package you mean toolboxes then just type
ver
in the command line

Use the ver command from the Command Window. It will tell you everything about your MATLAB installation.

Type:
webcam
in your Command Window. It should bring up a red error message that provides an underlined, bold link. Click on that link, then follow the instructions to download and install the MATLAB Support Package for USB Webcams (link).
It is only available for R2014a and later releases.
