The future of access and control

Solutions for intelligent access control

TZ Limited is at the forefront of electronic locking device development. Over the past 15 years, TZ’s intelligent, remotely actuated locking devices have been deployed in aerospace, military and automotive applications. TZ Smart Devices can sense, act, lock and audit activity based on secure instructions delivered on-line.  This enables rich data collection and diagnostic abilities.

Working together intelligently, a network of TZ Smart Devices can offer a secure environment and provide a complete, real time view of the state of that protected environment.  The ability to track behavior of people, things and data through space in real-time provides enhanced situational awareness which will allow the creation of more effective and efficient operating conditions and workflow practices.

Unlike conventional electronic locks, all TZ Smart Lockers use advanced Shape Memory Alloy (SMA) materials as actuators and embedded sensors to optimize operation. This technology offers a number of strong advantages including allowing for innovative physical designs and packaging.

TZ Smart devices work with a range of wireless and wired communications platforms to form network centric systems to solve real world problems for secure access as part of system wide solutions.


TZ Smart devices are more than just intelligent locks and latches, they incorporate advanced sensors to detect changes in the local environment, determine how they are being used and to then use this information to adapt behaviour or raise alarms and alerts.


TZ Smart devices use advanced 32bit microcontroller technology to achieve the extraordinary. Combined with a range of sensors and communications systems TZ Smart devices are at the forefront of edge computing devices.


The heart of a TZ Smart device is the use of advance shape memory alloy (SMA) instead of legacy motors and solenoids. SMA actuators use less power, do not generate Electromagnetic fields (EMF) and can be used in a range of physical formats not achievable with conventional approaches.
