The high security Circlelock portal equipped with StereoVision 3-D security system already offers a reliable way of ensuring single authorized person entry at unmanned pedestrian access points, but this new option provides a 3 stage security process beyond the previously offered:

1. Entering the Circlelock requires authorization from an access control system.
2. Once the authorized user is inside the Circlelock, the StereoVision system verifies that only one person is present.
3. When the StereoVision system has ensured only one person is present, the biometric device is activated to allow the user to be authenticated.

Passage is only granted when the single authorized user has been authenticated, thus ensuring fraudulent entry is not possible even if the authorized user is forced to give up their access control card or attempts to help another person through.

"Rather than offering a specific biometric technology, we have carefully designed a platform that allows clients to retain their existing system or choose a system from those already on the market that matches their individual requirements" says David Bunkall, director of group marketing for Royal Boon Edam Group Holding B.V.
