                 VICON INDUSTRIES REPORTS SECOND QUARTER RESULTS
HAUPPAUGE,  NY, May 17, 2004 - Vicon  Industries,  Inc.  (Amex:  VII), a leading
designer and producer of video security and surveillance systems, today reported
operating  results  for the second  fiscal  quarter  ended March 31,  2004.  The
announcement was made by CEO Ken Darby, who said the results principally reflect
the effect of lower sales and higher operating expenses.

Net sales for the second  fiscal  quarter were $12.2  million,  a decrease of 6%
compared  with $13.1  million in the second  quarter of the prior fiscal year. A
net loss of $901,000  ($.20 per share) was incurred  compared with a net loss of
$2,735,000  ($.59 per  share),  which  included a deferred  tax asset  valuation
charge of $2.1 million ($.45 per share), in the prior year quarter.

For the six  months,  net sales were $26.6  million,  an increase of 6% compared
with $25.1  million in the first six months of the prior fiscal year. A net loss
of  $779,000  ($.17 per share)  was  incurred  compared  with a net loss of $4.8
million  ($1.04 per share),  which  included the  combined  effect of a goodwill
impairment and deferred tax asset  valuation  charges  aggregating  $3.5 million
($.75 per share), in the prior year six month period.



Commenting  on the second  quarter  results,  Mr.  Darby said both  foreign  and
domestic  sales were down in the quarter.  Domestic  sales totaled $7.0 million,
down from $7.7 million,  while  foreign  sales were $5.2 million,  compared with
$5.4 million in the prior year quarter.  Gross profit margins increased to 37.0%
versus  35.5%  as a result  of  sales of  higher  margin  digital  products  and
favorable  foreign  currency  exchange rates.  Margin growth was tempered by the
write-off of $182,000 of first  generation  digital video  recorders.  Operating
expenses  increased  4% to $5.4  million  due  primarily  to higher  legal  fees
associated with the defense of a patent  infringement suit and increased foreign
sales office expense as a result of an unfavorable exchange rate.

Mr. Darby also said that new orders in the second  quarter  were $11.8  million,
and the backlog of unfilled orders at March 31, 2004 totaled $6.1 million.

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.
