XS4 Face architecture overview

Components

Icon	Description
XS4 Face Server	The core responsibility of the XS4 Face Server is to identify which user is attempting to access a door, and pass that identification on to the Access Control Server. In support of this, it receives information on users from the Access Control Server and Enrollment Service. It has no user interface; it is commissioned and managed via the XS4 Face Console.
XS4 Face Enrollment Service	Allows users to upload a picture of themselves that will be used for facial recognition. Users are invited to use the enrollment service when their details are entered into the Access Control System.
XS4 Face Device	The combination of XS4 Face C, XS4 Face CU, and the supplied cable that connects them.
XS4 Face Console	A management application for installing, monitoring, operating and decommissioning XS4 Face sites and servers. The Console is accessible on mobile and desktop computers via a web browser. The last 4 versions of Chrome, Firefox, Edge, Safari, Android Browser, and iOS Browser are supported. The Console is multi-language, the current language button on the left menu. Support languages are English, French, German, Dutch, Spanish and Arabic.
XS4 Face Connect	A set of hosted services that provide the infrastructure to support the deployment and maintenance of XS4 Face Servers. Connect is based within Microsoft Azure and maintained by Salto. XS4 Face Connect is regionalised, so that personal data does not leave the region in which the site is based. No biometric or personal information is stored within, or passed through, XS4 Face Connect. The XS4 Face Server consists of hardware supplied by the customer and software supplied by Salto. It is the responsibility of the customer to maintain it and keep the data backed-up.
Access Control System	The software platform (for example, Salto Space) used to control which users are able to access which doors.
