If you would like to familiarise yourself with Gravio, its architecture and user interface, we suggest something that does not require any hardware. The free version supports some basic computer vision models that can be activated by a connected network (ONVIF) or USB camera. It is not fit for any production environment as the authentication systems are not enabled for this version. If you like to try 3-4 basic hardware sensors to see how they behave, we suggest you go for the basic version, which you can sign up for in the Gravio Studio app downloaded from the Windows or Mac App Store. The standard package is recommended for production environments. It comes with 20 sensors of your choice. But the computer vision models are still limited to what we provide for you. The Enterprise package is the full package and includes a back-end for you, should you require one. The Enterprise package is also the only package that allows you to create your own computer vision models and much more
