Security has always been an important interest for human civilization. People utilise security gates to prevent intruders from their valuables. One of the common types of security gates is turnstiles.
Turnstiles are built to let only one person gain entrance through the gate at a time. This is why turnstiles have been seen to be very effective in securing several high-risk buildings such as military bases, banks, government buildings, hotels, and prisons.
However, turnstiles are not all the same. They are of different types. If you are considering the installation of a turnstile gate, you will need the type that best suits your security objectives. In this article, we shall look at five different types of turnstiles.
#1. Sliding Barrier Turnstiles
These are waist-high turnstiles that have sliding flaps pushed back into the sliding area. The working principle and smooth design make these turnstiles a good fit for indoor aesthetics for lobbies and hotels.
Depending on the type, there might be an anti-tailgating function. Though, people may be able to jump or pass items over these types of turnstiles. But they can be used to design an access control system that is wheelchair-friendly.
#2. Waist-High Turnstiles
As the term indicates, the length of types of turnstiles is waist-high. They are also known as half-height turnstiles. Usually, for you to open or pass the barrier, you would need to use a bar-coded ticket or an electronic key.
These turnstiles can enable you to create a multi-lane access control system to regulate pedestrian traffic in private and public places. Waist-high turnstiles can be divided into various types. It depends on the barrier technology used.
#3. Tripod Turnstiles
Tripod turnstiles are the combination of an optical sensor and a tripod barrier. As the name suggests, they normally have triple (tripod) arm barriers. But they may also come in single and double-arm barriers. The arm lowers into recesses in the cabinet when an authorized entry is sensed.
The tripod barrier rotates vertically and allows a person to pass at a time. They are usually found at bus terminals, train stations, public parking lots, and airports.
#4. Optical Barrier Turnstiles
The optical barrier turnstiles make use of infrared beams to prevent unauthorized access. The system sets off an alarm if it detects an unauthorised entry. And this will prompt the security personnel to come in.
These turnstiles are often seen in places where the use of physical barriers is considered unnecessary or unaesthetic. Such places include hotel lobbies, office buildings, sports stadiums, and other places.
#5. Swing Barrier Turnstiles
The swing barrier turnstiles are half-height turnstiles that have optical sensors. The swing barriers are made from top-quality toughened glass or stainless steel. These turnstiles can be integrated into access management systems and also ticketing systems.
When a valid entry pass is detected by the optical sensors, the barriers open, allowing the person to pass.
As we’ve seen, there are several types of turnstiles. Each of them has unique features. You can select the one that best fits your budget and security goals. Hopefully, this knowledge about these types of turnstiles will help you make an informed decision on the type of turnstile to buy.
