What is the difference between Tailgating and Piggybacking through a secure gate with access control?
Tailgating is when another person, whether an employee or not, walks through a secure door without the knowledge of the person who gained legitimate access through the secure door. This is a similar concept to when there is a car tailgating you on the freeway without your permission. You are being followed.
Piggybacking is when another person follows through a door WITH the permission of the person who has been given access. If someone is hugging you or actually on your back, this is called “piggybacking.” Only 2 technologies are capable of distinguishing between 2 hugging people and 1 large person. Humans and three-dimensional artificial vision systems.
There are several methods to stop vehicle tracking and piggybacking through secure gates. At mission critical sites, armed guards are often employed 24/7 at significant cost. An alternative to an armed guard may be the installation of a three-dimensional artificial vision system that can differentiate between humans and objects. This is the same proven technology that has been used for decades in the field of robotics and factory automation. Newton Security’s patented T-DAR technology is the world’s most trusted system for detecting and preventing people from being followed through secure doors.
The two types of entrances found in an anti-tailgating system are individual doors and a set of 2 doors in a secure space called a mantrap.
A single door anti-tailgating system has the ability to alert with sound and alarm, alerting security personnel of an unauthorized intrusion. Since there is only one door, this cannot be a man trap.
A man trap is a safe space with 2 or more doors. When 1 person enters the mantrap area, the T-DAR 3-D machine vision system performs a dynamic scan, confirming that there is only one person in the space. If another person enters the space, it is detected and since there are now 2 people in the space, an alarm sounds. The door on the safe side of the space is locked so no one can enter the space. Both people must exit the trap before the entry process can continue.
Here’s a pretty good demo of a man trap in action: http://www.youtube.com/watch?v=gYw0rskVHTU
