Steatite has introduced a comprehensive, high integrity tracking system. It presents the national security, border control and law enforcement sectors with an ultra-reliable, all-encompassing, end-to-end solution that is simple to implement and can be tailored to fit their specific operational requirements. What essentially differentiates it from alternative solutions is that it has been designed from the initial concept phase with the goal of providing irrefutable forensic evidence – through its sophisticated diagnostic resources, precision positioning and secure operational capabilities. The worn unit comprises a secure GPS tag with a robust ankle strap. A wide range of sensors are incorporated, which constantly acquire numerous forms of data concerning the wearer’s locality and the external environment, as well as other key parameters such as battery status, etc. Extremely sensitive, adjustable tamper alert mechanisms have been integrated, which are triggered if any attempt is made to break into the case or to cut the strap. The unit connects securely to a configurable web portal, which can be referred to in real time. This relies on geolocation data from multiple satellites and base stations, as well as access to state-of-the-art mapping sources, to determine the tag wearer’s exact position with very low possibility of error. Geofence notifications can be utilised to prevent the tagged subject from leaving (or entering) predetermined areas.
