      Sarasota,
        FL, July 19, 2005 - Invisa,
        Inc. (OTC BB: INSA), an electronic life safety and security company, announced
        today that it has been awarded a second U.S. Patent in connection with its
        electronic non-contact technology.
        Invisa provides unique and highly reliable sensing solutions for the safety
        and
        security industries. Invisa’s technology, which received its first U.S. patent
        in August 1994, is based on the scientific principals of
        capacitance.

      


      Invisa’s
        newest patent covers critical aspects of using its patented technology in
        safety
        applications. A unique aspect of capacitance based technology is versatility
        that permits sensing applications not otherwise possible or practical. Invisa’s
        technology uses capacitance to form electronic sensing zones around a Sense
        Element. We call this Sensing Element an “antenna”. Our most recently issued
        U.S. patent protects antenna designs and applications developed and used
        in our
        current and future safety products. 

      


      According
        to Carl Parks, Chief Operations Officer, “Invisa has devoted significant
        research and development resources to antenna design. The antenna is where
        the
“rubber meets the road” in capacitance based sensing. By utilizing different
        types of materials and maximizing installation and spacing techniques we
        optimize our sensing capability in various applications. We believe that
        the
        issuance of this patent recognizes and protects our unique developments in
        antenna design and development.”

      


      According
        to Steve Michael, Invisa’s acting President, “Over the years, many highly
        qualified inventors and well funded companies have attempted to harness the
        power and versatility of capacitance based non-contact sensing. We believe
        that
        Invisa’s breakthrough InvisaShieldTM Technology is the only capacitance based
        non-contact sensing technology proven to be stable and reliable for use in
        safety and security products. However, technology never stands still and
        we are
        committed to protecting our leadership position through ongoing R & D and
        through expanding our patent position. We believe that our newest patent,
        together with our other patent and four pending patent applications, represent
        a
        solid and growing patent position which enhances our competitive and technology
        advantages.”
