TZ fuses software control, remote locking and fastening, environmental sensing and real time dynamic analysis to enable unique devices to sense, act, lock and audit activity based on secure instructions delivered over the internet. This enables rich data collection and diagnostic abilities. TZ Devices use proprietary Shape Memory Alloy (SMA) actuation to drive locking mechanisms. SMA actuation is a lightweight, solid-state alternative to conventional actuators. TZ Device intelligence comes from an embedded system that consists of a microprocessor, energy switching, and integrated sensors that monitor status. Working together intelligently, a network of TZ Devices offers a secure environment providing a complete, real-time view of the state of that protected environment. The ability to track the behaviour of people, things and data through space in real-time provides enhanced situational awareness, allowing for the creation of more effective and efficient operating conditions and workflow practices.
