                 VICON INDUSTRIES REPORTS THIRD QUARTER RESULTS

HAUPPAUGE,  NY, August 14, 2003 - Vicon Industries,  Inc. (Amex: VII), a leading
designer  and  producer of digital  video  management  systems,  today  reported
operating  results for the third  fiscal  quarter and nine months ended June 30,
2003. The  announcement  was made by CEO Ken Darby,  who said revenues from new,
higher margin network video products offset the effect of lower sales.

Net sales for the third  fiscal  quarter  were $13.1  million,  a decrease of 9%
compared with $14.3 million for the previous fiscal year period.  Net income was
$30,000 ($.01 per share diluted),  compared with net income of $28,000 ($.01 per
share diluted) for the same period last fiscal year.

For the nine months,  net sales were $38.2 million,  a decrease of 6% from $40.7
million  reported for the year-ago period. A net loss of $4.8 million ($1.03 per
share diluted) was incurred compared with a net loss of $786,000 ($.17 per share
diluted) for the year ago period.  The current  nine-month  period loss includes
the combined  effects of a goodwill  impairment  charge and a deferred tax asset
valuation  allowance  aggregating  $3.5 million or $.75 per share diluted.  Both
non-cash charges were taken in the second fiscal quarter.

Commenting  on the third  quarter,  Mr.  Darby said sales of Vicon's new network
(digital) video  products,  ViconNet/Kollector  Elite (VK),  helped gross profit
margins increase to 40.3% compared with 35.5% in the year ago quarter. The third
quarter  was the first  full  quarter of product  shipments  for the  initial VK
models,  and  additional  ViconNet based products are planned for shipment later
this calendar year.

Darby said the  quarter  also  included  a  performance  compensation  charge of
$278,000  relating  to the  sale  of  certain  quantities  of VK  products.  The
performance  compensation  obligation of up to $810,000  maximum was part of the
1999 acquisition of QSR, Ltd., an Israeli digital video development company. The
success of VK products to date has resulted in performance  compensation charges
of $325,000 and $278,000 in the second and third fiscal quarters respectively.

Product development  expense,  including the performance  compensation  charges,
totaled  10.3%  and  9.9%  of  sales  for  the  three  and  nine-month  periods,
respectively.  Development efforts are principally focused on enhancing existing
VK products and creating new network enabled products. The Company will showcase
the latest version of its ViconNet  network video  management  system,  together
with soon to be available ViconNet compatible cameras, at the industry's biggest
trade show, ASIS, in September.
