Sentry Technology Wins $700,000 Contract Award

Ronkonkoma, New York, June 5, 2007 -- Sentry Technology Corporation (OTC Bulletin Board: SKVY) announced today that the Dallas Public Library has selected Sentry Technology to supply QuickCheck™ self-service kiosks and electromagnetic security systems over three years with the majority of the products expected to be installed in the initial six-month period. The total value of the contract will be in excess of $700,000. Sentry was chosen as a result of its competitive pricing, feature rich QuickCheck™ hardware and software as well as industry leading security system designs.

QuickCheck™ operates in a similar fashion to a bank ATM. Patrons gain access to the library’s circulation software via a user card and touch screen video monitor. A barcode or RFID chip on the book is read, security functions performed and a receipt is printed to tell the patron what books have been borrowed and when they are due to be returned. Once the process is complete, the patron exits the library through the security system without any intervention by library staff. The entire process is fast, user friendly and frees library staff from the circulation desk to perform higher-level tasks. The system includes statistical usage report software as well as remote diagnostic tools for management of the QuickCheck™ over a local network and via the internet.

“We are proud of being selected as the self-service supplier for Dallas Public,” said Peter L. Murdoch, President and CEO of Sentry Technology Corporation. “Sentry has served the library as a security system vendor for the past 4 years and being chosen to supply additional technology is an endorsement of our product quality and commitment to customer service.”
