For example, meeting rooms, server rooms, and kitchens * To connect rooms together on the floor plan, place **doors** between them, just as they are in reality * Add hardware such as cameras, beacons, and kiosks inside rooms or by doors on the floor plan * Rooms can be grouped together into optional **zones** when they share the same access rules, for example, rooms that only engineering teams have access to can be grouped into an engineering zone In the example below, * Doors are connecting rooms * Hubs are in Server Room A * Both Server Rooms are in a secure zone, highlighted in pink, and sharing the same access rules * The Kitchen and Reception are in a common areas zone, highlighted in green, and also sharing the same access rules
