Security Revolving Door

The SRD is a standardized, technology-driven, automatic secured revolving door designed to prevent tailgating, piggybacking and other unauthorized entry attempts while maximizing traffic flow. Ideal for unmanned, high-traffic entrances where a higher level of security is required, the SRD integrates easily with any access control system and provides fully automated, touch-free entrance control in an aesthetically pleasing design.


True Aunauthorized Entry Prevention

Unsurpassed facility entrance control

Alvarado’s Security Revolving Door (or SRD) is perfect for areas where a higher level of security is required. By combining advanced sensor technology with true quality craftsmanship, the SRD stands in a class of its own, making it a perfect fit for facilities where security is top priority. Typically installed at employee entry points, common application sites include universities, government facilities, test labs, and data centers.

The SRD can be configured for entry, exit or bidirectional authentication, allowing facilities to track occupancy totals in real-time, so facility mangers can easily see who is in their building at any given moment.

The SRD is also intuitive for users. Once an authorized visitor approaches the door and presents a valid credential to the reader, they can enter the available compartment, at which point the doors begin to rotate automatically, allowing for a seamless entry into the facility with little disruption to throughput rates. In fact, since visitors can enter and exit the lane at the same time, throughput rates for the SRD can reach up to 44 people per minute. Once the lane is clear the door returns to quarter-point and is ready for the next visitor. The SRD also supports card stacking, so visitors don’t need to wait for person ahead of them to enter before they scan their card. The door will allow the same number of rotations as the number of scans that were initially accepted.

The SRD comes in 3 available models that include:
SRD-S2: Bidirectional tailgate prevention and unauthorized entry on exit prevention.
SRD-S3: Same features of the SRD-S2 with the addition of piggyback prevention on entry.
