Pedestrian Entry and Exit Always Secure with Turnstiles
A system designed to work seamlessly with the endless traffic of people entering and exiting a building should be as unobtrusive as it is effective. While turnstiles and barriers keep unauthorized people out, they should also be as practical as possible for those with the right access.
Turnstiles provide superior access control by both detecting and deterring unauthorized entries.
The locked mode remains locked even when presented with a valid credential, and does not permit entry. You can find everything you are looking for regarding turnstiles at .
Pedestrian Access Control
When entering a facility, the first point of entry is typically a door. A common solution to secure the facility is to add a card or biometric reader and electric locks to the door. While a reader and lock require valid credentials to unlock the door, they cannot control how long the door is open or how many people have entered. Additionally, a second person can tailgate when the door is opened. Furthermore, a normal door cannot restrict the direction of passage; when opened for entry, it also allows for exit. Unlike doors, turnstiles can limit the number of people who can enter and exit based on credentials and control the direction of passage. To enter through a turnstile, a person must first present valid credentials. The turnstile will then open and allow only one person to pass before immediately locking again. Some turnstiles have advanced detection capabilities to recognize and report scenarios like tailgating, free passage, and forced passage. It will trigger an alarm, alert the user, and notify the security center if an unauthorized entry attempt occurs. Turnstiles also offer the flexibility to implement variations. They can operate in a single direction or bi-directionally. Passage modes are independent for each direction and include free passage, controlled passage, or locked. Free passage mode allows unauthorized entry, typically used when users do not need to present credentials to exit. Controlled passage requires valid credentials before permitting entry.
