Portable Security Systems

The PSS contract is an evolutionary effort in its fourth generation performed for an elite division within the DHS over the past six years. The PSS is a secure, portable, expeditionary security system that includes advanced, cutting-edge Electro-Optical/Infrared (EO/IR) sensors, processing, software, firmware, and wireless technology. STS was tasked by DHS to perform a capability gap analysis on their existing potable, physical security system. This analysis led to a contract to design, develop, test, train, and deliver a customized complex system of systems expeditionary, lightweight, rapidly deployable wireless Command, Control, Communications, Computers, Intelligence, Surveillance & Reconnaissance (C4ISR) PSS. This is the fifth PSS contract STS has performed.


The primary objective of the initial contract was to provide Research & Development (R&D) services included performing a technology gap analysis of their current capabilities and recommending solutions. Working with the customer and technology experts, STS developed the PSS solution (pictured at right) providing increased early warning, enhanced situational awareness, and increased force protection. STS integrated multiple technologies with customer legacy equipment into a complete solution set. In less than three months, STS conducted the technical development; accomplished the technical integration; completed testing, evaluation, and demonstration; trained the operators; performed operational integration; and provided technical support services for the PSSs.

STS has achieved all objectives and milestones on-time and on-budget to date during this on-going contract, upgrading the existing seven PSS systems and executing design, development, procurement, integration, and fielding of additional new equipment. STS demonstrated flexibility and responsiveness to the customer’s needs and has exceeded all schedule and technical requirements within the original costs of the PSS contract. Due to the success of the PSS, the DHS customer has issued contracts to STS totaling $3.87M.
