Case Studies

Detectors for sub-stations

by Mark Rowe

Xtralis reports that its PRO E-PIR detectors performed with the highest detection reliability and the lowest false alarm rates of all passive infra-red sensors evaluated by Sensei Solutions, the Smart Grid security firm, whose products protect remote electrical sub-stations in the United States.

Sensei ranked Xtralis perimeter sensors to deliver fail-safe security. Xtralis ADPRO PRO E-PIRs, including wired and wireless, long range curtain and volumetric detectors up to 220m, were evaluated and selected by Sensei. PRO E-PIRs features 360PROtect for 360 degree protection, 3D protection for twisting tampering detection, an iCommission mobile app for one-man installation, and wireless communication.

Robin Thompson, CEO and Founder at Sensei Solutions, said: “The Xtralis PRO E-PIRs outperformed every other detection sensor we tested, including competing PIR detectors. Reliable long-range sensors combined with video analytics delivers extremely low false alarm rate (FAR) with very impressive probability-of-detection (PD) performance. Sensei’s MasterMind sensor fusion software makes this possible by integrating signals from multiple sensors from Xtralis and off-the-shelf video analytics using geo-referenced signal processing technology. This level of performance is what’s required for large-scale multi-site deployments where excessive FAR significantly diminishes the value of the security dollar investment. Together, Xtralis sensors and Sensei Mastermind software combine to deliver an unbeatable level of performance.”

The largest energy provider in the USA, with over 5000 substations, came to Sensei for a solution to protect their sites more economically. A system using fixed beams and video was prone to false alarms, causing unnecessary expense, and racked up cellular communication bills related to the video transmission of thousands of false alarms. Sensei selected a problematic substation for a detection trial which resulted in the Xtralis PRO E-100H PIR detector being selected. The PRO E-PIRs integrated with Sensei’s MasterMind product which manages, captures and aggregates data from all devices to allow the engineering, asset- management and security staff for remote utilities to organise their response .

At substations, cable trenching is costly due to topographical anomalies, as well as national and local safety standards. ADPRO wireless PRO E-PIRs offer the makers say protection up to 120m per detector, and it is claimed three times the detection reach of any competitor, without cable trenching. The PRO E-PIRs can communicate intelligently with adjacent PIRs to ensure threats moving from one protection zone to another are tracked. Visit: www.xtralis.com/criticalinfrastructure.
