Turnstile

eSSL Security

A Turnstile is a form of gate which allows one person to pass at a time. It can also be made so as to enforce one-way traffic of people, and in addition, it can restrict passage only to people who insert a coin, a ticket, a pass, or similar. 

Why Turnstiles?

From a business standpoint, turnstiles give an accurate, verifiable count of attendance. From a security standpoint, they enable security to efficiently isolate potential trouble or to confiscate any prohibited illegal materials.

Security in establishments and offices has never been more important. The increase in rate of unauthorized break-ins has led many business organizations to invest on security and access control systems. Installing security turnstiles is one of the things business owners do because of the advantages they provide. One of the more important benefits of using turnstiles is they help provide a more secure access or entry control at specific areas within a building or establishment.

Depending on the type of turnstiles used security teams can limit access to buildings to authorized personnel and help them identify premises visitors from tenants. Another advantage is that these turnstiles are quite helpful at keeping track of the number of people going in and out of an amusement park, providing simple solutions to determine the number of people in reserved seating and general admissions to the venue.

Most importantly however, these turnstiles, unlike human guards can work continuously 24 hours a day, seven days a week. They don’t get tired, so they don’t need to leave their posts to take breaks. This is quite helpful for high security areas such as airports. 

How it works?

Turnstiles often use ratchet mechanisms to allow the rotation of the stile in one direction allowing the passage of an outside signal into a coaxial cable but preventing rotation in the other direction. The user inserts a ticket or pass into the slot, from which a barcode is read; if access is to be granted, a sensor determines the speed with which the user passes through, and sets the electric motor to turn the turnstile at the corresponding speed. Some styles are designed to allow entry only after a payment (actual coins and tokens) is inserted. Turnstiles are often also used for counting the numbers of people passing through a gate, even where payment is not involved.
