A new dimension in security access

Security is playing an increasingly important role in our daily lives.The emerging threats in society have resulted in a growing demand for access control systems. Whether you are designing an entrance for a new hospital, airport or office building; more and more places require you to specify security doors and barriers that will only open for authorised persons.

HIGH SECURITY DOORS

Swing doors allow virtually anyone to follow authorised users into a building once a door is unlocked and opened. Unlike swing doors, security doors and barriers allow entry for only one authorised person at a time. Interlocking door systems and security revolving doors ensure the public area is completely separated from the secured area. Security revolving doors offer the advantage of much higher traffic capacity than interlocking door systems. Up to 20 authorised persons per minute can pass through a security revolving door. With a fourwing revolving door this is even possible in two directions simultaneously. You will often find high security doors in government buildings, banks, airports and corporate offices. These entrances often render surveillance by a third party, such as guards, unnecessary.

PIGGYBACKING AND TAILGATING

When two or more persons enter a security door on one authorisation, it is known as piggybacking. Tailgating occurs when an unauthorised person follows an authorised user in a following or opposite segment of a security revolving door. Both security revolving doors and interlocking doors must prevent either of these happening if they are to be effective in high security areas. Tailgating can be prevented with sensors or contact mats, while piggybacking is traditionally prevented with a contact mat or a weight system that verifies whether the user is alone in the door. A weight system is a verification system that is installed in the floor space of the entrance. If the authorised user, plus any luggage, exceeds the pre-set weight, the user will be rejected.

STEREOVISION

The latest development in security access is called StereoVision. This is a groundbreaking camera and sensor technology that monitors the interior of the high security door in three dimensions, making it capable of distinguishing between one person, one person with objects or two persons. This new generation security system recognises shape, size and volume in three dimensions and analyses the data to determine the number of people attempting to enter on one authorisation. Any attempted violation is detected and the door is able to block entry. The camera system is integrated in the ceiling of the entrance, reducing the need for floor adaptations. This unique 3D technology provides an unprecedented level of accuracy in security access, detecting piggybacking reliably and accurately without reducing the throughput capacity of the entrance or compromising the building’s design aesthetics.
