US Sensor Systems Selected for Multi-Site Maximum Security Project

NORTHRIDGE, Calif., Nov. 12, 2010 /PRNewswire via COMTEX/ -- US Sensor Systems Inc. (USSI), a subsidiary of Acorn Energy (Nasdaq: ACFN), announced today that its GroundAlert fiber optic perimeter security system has been selected for a multi-site maximum security project in Latin America valued at approximately $0.6M. USSI is part of the team headed by PCSC of Torrance, CA, a leading global security solutions provider and manufacturer of building controls and security information systems.

"When it comes to total price and performance, USSI's technology stands head and shoulders above the competition," stated Mas Kosaka, CEO of PCSC, "and these initial sites could lead to hundreds of sites planned for the entire project." USSI's new fiber optic perimeter security system, powered only by light, utilizes highly sensitive, yet unobtrusive fiber optic microphonic sensing cables buried along a fence perimeter to detect attempts to dig/tunnel underneath the fence.

"The worldwide demand for security systems is dramatically increasing, yet the existing decades-old security technology cannot scale up to meet the demand due to its high installation and upkeep costs," states Jim Andersen, USSI CEO.

"Because our optical sensor cables require no electronics or electrical power in the field, the savings in installation and maintenance costs are enormous, and all system calibrations/adjustments can be performed from a desktop in a control room." About US Sensor Systems US Sensor Systems Inc. ("USSI") designs, integrates, manufactures, and sells fiber optic sensing systems and solutions for the Energy and Defense markets.

USSI utilizes all-optical fiber sensing technology for its state-of-the-art sensors. Use's proprietary optical fiber and electronics combine to form the sensor system. It is designed to replace the legacy electronic-based sensor systems at a lower cost and with improved performance and reliability. For more information visit the USSI website at:
