Alvarado dormakaba Group has released the Alvarado Security Revolving Door (SRD), a secured revolving door designed to not only detect but prevent tailgating and piggybacking attempts. The SRD detects unauthorized passage attempts through overhead sensors that prevent the passage from being completed while still maximizing traffic flow. The SRD can be configured for entry or exit only or bidirectional authentication, allowing facilities to track occupancy in real time. It is compliant with building codes and available in three models tailored to the customer’s security needs.
