For carparks, aluminium roller grilles are often used to secure the carpark entry. This was the case for this inner city Auckland apartment complex. The roller grille allowed 24 hour access to the underground carpark, while maintaining security by remaining closed except when the swipe card was used for entry.
Unfortunately theft from vehicles was occurring even with the roller grille in place. Attempts were made to secure the grille with magnetic locks at the bottom, but the thefts continued.
