                      VICON REPORTS SECOND QUARTER RESULTS

HAUPPAUGE,  NY, May 16, 2005 - Vicon  Industries,  Inc.  (Amex:  VII), a leading
designer and producer of digital video security and surveillance systems,  today
reported  operating  results for the second fiscal quarter ended March 31, 2005.
The announcement was made by CEO Ken Darby.

Net sales for the second fiscal  quarter were $12.8  million,  an increase of 5%
compared  with $12.2  million in the second  quarter of the prior fiscal year. A
net loss of $1,169,000 ($.26 per share) was incurred compared with a net loss of
$901,000 ($.20 per share) in the prior year quarter.

For the six  months,  net sales were $28.4  million,  an increase of 7% compared
with $26.6  million in the first six months of the prior fiscal year. A net loss
of $1,909,000 ($.42 per share) was incurred compared with a net loss of $779,000
($.17 per share) in the prior year six-month period.

Commenting on the second quarter results, Mr. Darby said U.S. sales declined 11%
to $6.2  million  while  foreign  sales grew 26% to $6.6  million.  The  foreign
revenue growth was all attributable to Videotronic, Germany, whose operating and
intangible  assets were acquired October 1, 2004.  Shipments and new orders were
well below plan as the  Company  experienced  a  slowdown  worldwide  in closing
projects during the quarter, noted Mr. Darby.

At  quarter  end,  U.S.  senior  sales  management  was  restructured  under Tom
Finstein,  EVP, who assumed  responsibility for business development,  sales and
marketing  functions.  In addition,  Bret McGowan,  VP  Marketing,  moved to the
position of VP, U.S. Sales and Marketing, reporting to Mr. Finstein.

Mr.  Darby  said  operating  results  for the  quarter  were  influenced  by the
following factors:

1.   The Company  incurred  $249,000  of legal  expenses  ($395,000  for the six
     months) defending itself in a patent  infringement  suit. On April 11, 2005
     the U.S.  Patent  Office,  in ruling upon  Vicon's  petition to  re-examine
     plaintiff's patent, issued an order granting  re-examination of the patent.
     The Company continues to vigorously defend itself in this matter.

2.   The Company's new German subsidiary,  Videotronic Infosystems,  incurred an
     operating loss of $87,000 in the quarter ($243,000 for the six months). The
     operating  losses  were  expected  in  view  of  the  transitional   issues
     Videotronic  would face emerging from bankruptcy.  Since the acquisition on
     October 1, 2004,  Videotronic  has made good  progress in  re-building  its
     customer  base and  Vicon's  investment  in  Videotronic  now  totals  $1.9
     million.  Also in the second quarter, the Company recorded an extraordinary
     gain of $211,000  relating to the recovery of Videotronic  assets in excess
     of their purchase price.

3.   In the second quarter,  the Company recorded a $103,000 charge for employee
     severance payments.

4.   A  performance-based  compensation  charge of $90,000 was also taken in the
     quarter   relating  to  the  1999   acquisition  of  our  Israeli  software
     development  company,  Vicon  Systems,  Ltd.  The  expense  was part of the
     original  acquisition  cost and was earned only when certain  products were
     developed by them and sold by Vicon.

While the  operating  results for the period are  disappointing,  the  Company's
financial position remains strong. Other than mortgage debt of $2.6 million, the
Company has no bank debt and had over $4 million in cash at quarter end.

At a recent industry trade show in Las Vegas, the Company showcased  ViconNet(r)
3.X, the next generation  software  application  that powers a new  Kollector(r)
family of video  servers/recorders and IP cameras.  ViconNet(r) 3.X is scheduled
for  customer  shipments  later  this  year.  "The  significant   digital  video
development  investment  the  Company  has  made  over the  last  several  years
positions us well for the future.  Digital (IP) video  applications are forecast
to  dominate  the video  surveillance  market  and we will be ready for it" said
Darby.

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.
