U.S.  PATENT  OFFICE ISSUES  NON-FINAL  OFFICE ACTION WITH RESPECT TO LECTROLARM
PATENT RE-EXAMINATION PROCEEDINGS

HAUPPAUGE,  NY, May 8, 2006 - Vicon  Industries,  Inc. (Amex:  VII) In May 2003,
Vicon,  among others,  was sued for patent  infringement  by  Lectrolarm  Custom
Systems,  Inc. Since that time,  Vicon has vigorously  defended itself believing
the patent was invalid.  In January 2005,  the Company filed a petition with the
U.S.  Patent Office asking for a  re-examination  of the patent based upon prior
art by Vicon and another defendant. In April 2005, the U.S. Patent Office issued
an order granting the re-examination.

On April 26, 2006,  the U.S.  Patent Office issued a "non-final  office  action"
rejecting the first 6 of the 7 claims in the  Lectrolarm  patent.  Lectrolarm is
not  asserting the 7th claim in the patent  infringement  suit.  Lectrolarm  has
multiple appeals available to it in the U.S. Patent Office and,  thereafter,  in
the Court of Appeals for the Federal Circuit.

Vicon Industries, Inc. designs, manufactures, assembles and markets a wide range
of video systems and system components used for security,  surveillance,  safety
and communication purposes by a broad group of end users worldwide.
