Sentry Technology Wins Library Self-Service Contract

Ronkonkoma, New York, November 7, 2007 -- Sentry Technology Corporation (OTC Bulletin Board: SKVY) announced today that the Calgary Public Library placed an order for an additional eight QuickCheck™ self-service kiosks. This is the fourth order for QuickCheck™ systems by Calgary following a public tender process. When the installation of the latest order is complete the library will have twenty-two self-service systems in service.

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 pleased with the continuing success of our self-service library program,” said Peter L. Murdoch, President and CEO of Sentry Technology Corporation. “We have 38 QuickCheck™ units on back order to be delivered during the balance of 2007 valued at approximately $700,000. Both our library and video businesses remain strong with the expectation for continued growth in 2008.”

Sentry designs, manufactures, sells and installs a complete line of Closed Circuit Television (CCTV) solutions, Electro-Magnetic (EM) and RFID based Library Management systems including QuickCheck™ patron self-service kiosks. The Company’s products are used by libraries to secure inventory and improve operating efficiency, by retailers to deter shoplifting and internal theft and by industrial and institutional customers to protect assets and people.
