Flap barriers are high speed gates with excellent operating time. Infrared sensors, wing arms, reader and access control mechanism are the core components of a flap barrier. These are mainly used to control the flow of visitors like passengers or pedestrians at metro stations, or amusement parks, where tickets or token are acceptable. Theses high speed gates are commonly seen in metro stations.
Functions of turnstiles are very similar to flap barriers. They can be used to control pedestrian flow as well as monitoring attendances. They may or may not have ticket or token system. Turnstiles are not only cheaper, but also simpler than flap barriers. Despite the simplicity, they lack in speed as compared to flap barriers.
Advantages
Main advantages of flap barriers are to keep count of crowd. More over that it saves time because their operating time is very less. Flap barriers are also used to collect ticket and tokens in a systematic manner while charging an entry fee. Turnstiles can be used to keep count of visitors for security measures. More over this safety measure turnstiles used to maintain the queue because it does not allow two individuals enter at the same time.
Technical features:
Flap barriers are totally based on electronic systems and while the power is out, it remains open. That is why we can consider it normally closed system which uses power to remain closed and when tickets or another fee variants inserted to the system it allows one individual to cross.
Turnstile may or may not be electronic. These can be operated electrically and manually.
These are the main difference between flap barriers and turnstile because flap barriers have to be electrical. Turnstiles can be seen at amusement parks, offices colleges and in those place where it is needed to control the flow of crowd at the entrance.
Both flap barriers and turnstile can be used at outdoors as well as indoors.
Flap barriers also comes with RFID (radio frequency identification). This feature is quite effective for restricted areas because frequency identifications are mainly issued by the companies for their employees as well as it saves more time.
These barriers can also be coupled with face recognition systems to make it more compatible that fits well in every sectors.
These systems are now being used in government sectors as well. They are needed to keep a count of individuals or visitors at institutions so these can be used with a visitor management software to keep a count of checkouts or check ins.
In a scenario a visitor scans his mifare RFID card on a flap barrier, the system immediately deducts the appropriate amount and shows the remaining balance on the LCD screen. Both flap barriers and turnstiles can work on either uni and bi directions.
On basis of functionality and characteristics there are three basic types of turnstile. Turnstile vertical tripod and turnstile bridge tripod are quite similar. Both are uni and bi-directional and automatic with drop arms. Both uni and bidirectional turnstiles have same speed as 35 persons per minute. Latest version of these two compatible with RFID reader and access control. Another type of turnstile comes with full height feature and it is used in factories or plants on a major scale. The main concern of using full height is regarding safety measurements.
