Description
The AC-91H4 combination lock, along with its accompanying TTLock mobile application, is designed for the purpose of physical access control.
It can operate independently or as part of a more complex system. Access control can be managed remotely via a smartphone or physically using a proximity key fob (operating on the Mifare 13.56 MHz standard) or a digital PIN code. All device functions are programmed using the TTLock mobile application available for iOS and Android platforms, which communicates with the lock via Bluetooth. The application allows for granting permissions to other users, generating PIN codes, and sending them via SMS, among other methods.
In addition to the basic access control functions, the combination lock is equipped with a work time registration (WTR) function, enabling insight into the history of entries and exits for individuals required to verify the time spent in the secured facility.
