Two-door access control systems are used to restrict access to a specific area or building. These systems typically use electronic locks and card readers or biometric scanners to grant or deny access to authorized individuals. The system can be programmed to allow access to certain individuals during specific times of the day or week, and can also track who has entered and exited the controlled area. The system can also be integrated with other security systems such as CCTV cameras and alarm systems for added security.

Anti-passback is a security feature commonly found in electronic access control systems. The function prevents an individual from passing their access credential (such as a card or key fob) to another person to gain unauthorized access.

There are two types of anti-passback:

  • Hard anti-passback: When an individual uses their access credential to enter a controlled area, the system will not allow them to use the same credential to exit until a certain amount of time has passed or another individual has used their own credential to enter the area.
  • Soft anti-passback: Similar to hard anti-passback, it will only prevent the individual from exiting the area if they have not used a different credential to enter the area.

Anti-passback helps to ensure that only authorized individuals are able to enter and exit controlled areas, and can also help to track who has entered and exited the area.
