      INVISA
        IN FINAL PRE-PRODUCTION TESTING OF NEW MUSEUM SECURITY PRODUCT


      


      Sarasota,
        FL, July 28, 2005
        -
        Invisa, Inc. (OTC BB: INSA), an electronic life safety and security company,
        announced today that its planned electronic museum security product has entered
        pre-production testing. This represents one of the last remaining steps before
        the museum security product can be introduced later this year. 

      


      Invisa
        began developing and testing its planned sensing product for museum security
        in
        2003. The planned museum security product is based on Invisa's technology
        that
        is currently used in its SmartGate®
        brand
        safety products. The museum security market is an important market opportunity
        in addition to representing Invisa's first contact with the broader security
        industry. 

      


      In
        September 2004, Invisa was honored with the opportunity to present its planned
        security product to the International Association of Museum Facilities
        Administrators (IAMFA) Conference in Boston, MA. The conference was hosted
        by
        five Boston area museums and was attended by approximately 200 museum
        administrators from around the world. Features suggested at the IAMAF Conference
        and requested by museum security professionals based on in-museum testing
        have
        been integrated into this pre-production design. 

      


      Invisa's
        planned product, which utilizes patented InvisaShieldTMTechnology,
        is a robust and advanced implementation of capacitive sensing for the museum
        and
        private collections markets. This product is designed to solve a specific
        security challenge, namely, providing open viewing access to art and exhibits
        while protecting them from vandalism, undesired contact and inadvertent damage.
        

       

      According
        to Dan Lohnes of Essex Alarm & Security Inc., a highly respected New England
        security installation company that specializes in museum security, "I have
        used
        Invisa's initial prototype over a sustained period of time, in a broad range
        of
        security applications, in actual museum conditions. I believe that Invisa's
        planned product will meet an industry-wide security need.”

      


      According
        to Carl Parks, Chief Operations Officer, "We believe that our patience in
        developing our planned museum security product has paid-off. This pre-production
        design incorporates our new digital technology platform and important features
        requested by the industry. We believe that input from museum professionals
        that
        is based on hands-on experience is essential to our ability to meet the needs
        of
        the museum industry. Museums and security professionals interested in
        participating in Invisa's current field test program are invited to contact
        me
        at 941-355-9361.”

      


      According
        to Steve Michael, acting President, "Our planned product represents an effective
        way for museums, private collections and security professionals to provide
        security sensing that was not previously possible. Based on industry input,
        we
        believe that our planned product will meet the pressing demand for electronic
        non-contact sensing which is user-friendly and reliable in the worldwide
        museum
        and private collection markets."
