Integrated Security Systems, Inc. (ISSI), (OTCBB:IZZI) today announced that it's wholly owned subsidiary, Intelli-Site, Inc.'s Intelli-Site(R) product has been installed at the Arlington Hospital Center NCIU facility in Arlington, Va.

The new NCIU security system, part of a $1.2 million facility upgrade, is a complex integration of CCTV, Access Control, Radio frequency bands and custom designed Graphical User Interfaces. Intelli-Site(R) software provides key integration and control for the security system.

"Recent events in the news have highlighted significant weaknesses in the protection of our most vulnerable citizens. We see Intelli-Site(R) as playing a critical role in the solution to this problem and hope to participate fully in this vital market segment going forward," says G.M. Ulibarri, President and CEO of Intelli-Site, Inc.

The new cutting-edge communications system installed in the Unit allows hospital personnel to quickly and easily detect and respond to an emergency within any of the Women & Infant Health areas. Computerized floor plans at the nurses' station automatically display which room needs assistance, so that nurses, physicians or security personnel can be rapidly dispatched.

"This is the monitoring technology of the future, and Virginia Hospital Center is probably more advanced in adopting it than any other hospital in the country. Parents will feel reassured that their infants' safety and security, as well as their medical care, is being constantly monitored in the new NICU," says Jim Hugler, CEO of Secure Technical Engineering, which is implementing the system at the Hospital.
