The SDK is able to work offline on basically every system. For real-time performance, we suggest to use at least an Intel i3 2.5 Ghz for 640 x 480 resolution. An Intel i5 3.5 GHz is recommended to achieve higher resolution. A full HD web camera (eg: Logitech HD pro series) is required for enhanced tracking accuracy. An internet connection is required for activation and license validation, depending on your license type.
