If you want to create a sign which uses the Gender detection AI tool then you need to create an account in Microsoft. 

The SignStix gender detect demo signs depend on a service from Microsoft in order to process images from the camera.

There is a free azure account available, this will process a limited number of transactions. (Twenty per minute).

Once you have signed up for an account (free or paid), let us know and we can help you integrate it within SignStix.
