Schließsystem in Wohnhausanlage

Residential complexes

Residential complexes | Residential properties | Student residences

Shared living spaces are all the rage in modern residential living: a rooftop swimming pool or meditation space in the basement. In a locking system with electronic component products that are used for shared spaces and mechanical component products that are used in doors to property. Consequently, residents benefit from increased convenience and operators spend less time on managing the master key system. EVVA knows how.

Your requirements:


  • Event log Because your tenants want to know who accessed which facility at which time if an expensive mountain bike goes missing or if they would like to set up access schedules to gyms or swimming pool facilities
  • One system for all purposes Because your tenants would like to unlock their properties, bike sheds and swimming pool facilities using only one type of medium (e.g. combi key)
  • Key copying protection Because access authorisations and reordering keys must follow specific, secure processes
