Turnstile access control systems are frequently used in construction sites, corporate buildings, modern residential, sports, government, and educational facilities as a typical physical security solution. These regulate pedestrian entry so that they can easily move into and out of the site while maintaining a level of security that prevents access to unauthorized individuals. When a valid credential is presented, security entrance gates allow access to only one person at a time. However, several common entry frauds are discovered every day. Below, we’ve listed seven of them.
1. Tailgating and Piggybacking
Piggybacking and tailgating both refer to the practice of following closely behind an authorized user. Tailgating and piggybacking vary in that tailgating involves an unauthorized user following an authorized person without their help, while piggybacking involves an authorized person assisting the unauthorized person in entering a secured location. When more than one person enters the turnstile lanes at once, an alert is detected and sounded by the infrared sensors built inside optical barrier turnstiles.
2. Reverse Way
It means attempting to enter the passages from the opposing side. The optical pedestrian turnstiles can be set up to allow access in either direction, such as entry-controlled / exit-free, entry-controlled / exit-free, or entry-free / exit-free. However, the LED indicator on the cabinet displays a green arrow when people are allowed to pass and a red cross when they are not. When a person approaches the security entrance gates from the wrong side, their infrared sensors detect the person and sound an alarm.
3. Safety Zone Time Out
The area close to the place where the turnstile barrier opens is referred to as the safety zone. A fraud attempt is made if an authorized user occupies this space for an excessive amount of time, causing the turnstile machine to remain open and allowing unauthorized users to pass. Our touch-free turnstiles such as sliding turnstile systems, swing turnstile gates, optical flap turnstiles, and speed gate turnstiles are supplied with advanced detecting systems that sound an alarm if the users stay in the safety zone outside of the given time.
4. Crawl Under
It refers to an attempt to crawl under electronic turnstile gates. The person’s body crawling is detected by sensors at the base of a turnstile system. On the other hand, the full-height pedestrian turnstile comes without an infrared sensor, but it is impossible to crawl under them because of their floor-to-ceiling structure.
5. Climb Over
It refers to attempts by fare dodgers on metro systems to climb over the turnstile access control system. Some smart security turnstiles such as full-height biometric turnstiles, sliding optical turnstiles, and speed gate turnstiles can be equipped with high physical barriers that effectively prevent attempts of climbing over.
6. Force Open
Manually forcing open the mechanical turnstiles’ barriers. Most crowd control turnstiles can not be opened manually once they close, while the alarm system will sound if such an attempt is detected.
7. Lane Intrusion Time Out
It is also considered entry fraud when unauthorized users wait in the entry area for other authorized users to open the barrier so they can through. The infrared sensors of architectural turnstiles monitor the lanes all the time and sound an alarm if such action is detected.
