2N has upgraded a residential project in the UK to improve security and enable residents to take calls on their phones when they are not at home.
Sperry and Gilbert House are residential units providing both private and social housing flats. The buildings are part of a larger complex though each apartment block is standalone. The two blocks share a main gate and there is access into both buildings from the basement car park. The two are also linked by doors on five floors that need to remain locked for security, although certain groups — cleaners, maintenance, for example — need full access.
