International. Boon Edam highlighted the 35th anniversary of the launch of the Circlelock lock-type portal. The company said the demand for this security entrance, first built in 1984, continues to grow. Currently, Circlelock is used in thousands of sensitive facilities around the world, including data centers, government and military buildings, and commercial campuses.
The Circlelock owes its longevity to its ability to meet the true intent of multi-factor authentication, which is that only one person — and the right person — can enter a secure area. The portal can be integrated with any access control system, and biometric scanning technologies can be mounted within the portal at an optional support station.
A user can present a credential to enter the portal (which scans the inside to make sure the user is alone) and then present their face, iris, fingerprint or hand to confirm their identity before the second door opens.
Prevention of piggybacking with sophisticated technology
Circlelock combines premium construction with the intelligence of a sophisticated near-infrared detection technology housed in the ceiling, called StereoVision 2. When a user enters the portal, StereoVision 2 scans the compartment to verify that the user is alone before allowing them to enter a secure facility.
The company says StereoVision 2's technology has been continuously improved for decades and today can work reliably in a wide variety of lighting environments. Its reliable performance over the years has proven to be the only safe way to prevent intrusion into a safe area without the excessive false rejections presented by previous filtration technology.
Easier installation than conventional locks
Unlike conventional on-site locks, Boon Edam's mantrap Circlelock portal is a fully tested and safe solution that can be installed in two days. There is no need to mount sensors or cameras and perform continuous tests to check for blind spots.
In addition, the Circlelock's seamlessly integrated hardware and software offer the highest levels of reliable security without the need for guard supervision, providing a quick return on investment. Another popular option today is the use of bullet-resistant glass for cylindrical walls and sliding doors.
