               CompuDyne Reports EPS Loss of $0.28 for
                          First Quarter 2007

    ANNAPOLIS, Md.--(BUSINESS WIRE)--May 11, 2007--CompuDyne
Corporation (Nasdaq:CDCY), an industry leader in sophisticated
security products, integration and technology for the public security
markets, today reported a net loss of $0.28 per share for the first
quarter of 2007, compared to a profit of $0.10 per share reported in
the first quarter of 2006. Revenues in the first quarter of 2007 were
$31.1 million, down from $40.5 million in the first quarter of 2006.
EBITDAS for the first quarter of 2007 was negative $0.4 million, down
from a positive $2.5 million in the first quarter of 2006. First
quarter 2007 results were negatively impacted by low backlogs entering
2007, and a delay in the award of new projects, resulting in flat
backlogs rather than the increasing backlogs that had been
anticipated. While results in the first quarter were somewhat worse
than we had anticipated, we continue to believe that these are
temporal impacts and that high levels of new business activity should
eventually translate into increasing backlogs and increasing revenues
in the coming quarters.

    Institutional Security Systems ("ISS") revenue was $11.2 million
in the first quarter of 2007 compared with $13.4 million in the first
quarter of 2006. Pre-tax loss was $1.3 million in the first quarter of
2007 compared to a $0.1 million pre-tax income in the first quarter of
2006. ISS revenues and earnings were negatively impacted by low
backlogs, and delays in planned project starts already in backlog.
Recent increases in new business activity, as evidenced by strong
award levels in March, and a significant amount of business that is
pending formal award, suggests that backlogs will improve throughout
the year. Pipeline activity is the strongest it has ever been,
reflecting strong latent demand for additional jail and prison
capacity at all levels of the market - local, state and federal.
Especially encouraging is the increasing acceptance of ISS' "MaxWall"
modular steel jail cell product, which has the potential of
significantly expanding ISS' market. ISS backlog declined by $0.8
million to $63.9 million during the quarter.

    Attack Protection ("AP") revenue was $4.4 million in the first
quarter of 2007, down significantly from $11.7 million in the first
quarter of 2006. Pre-tax loss was $0.9 million in the first quarter of
2007, compared to pre-tax income of $1.2 million in the first quarter
of 2006. AP's Norshield business, which produces bullet, blast and
attack resistant doors and windows and vehicle barrier systems,
completed a very large embassy order in 2006. Norshield continues to
work to replace this volume, however backlogs declined sharply during
2006 while working on this project and have only recently started to
recover, presaging continuing low volumes in this business in the
coming months of 2007. The delayed receipt of a substantial change
order request materially impacted results. Norshield has undergone
significant "right-sizing" efforts during 2007 resulting in cost
reductions of $1.2 million on an annual basis, and has adopted a
strategy of offering to install its products for customers rather than
just sell the products. This new strategy, combined with a closer
integration with ISS, is expected to expand Norshield's market
potential while improving its efficiency. AP's Fiber SenSys ("FSI")
brand business, which is one of the world's largest supplier of fiber
optic based perimeter alarm systems, almost doubled its revenues in
the first quarter of 2007 compared to the first quarter of 2006. FSI
is expected to continue to improve revenues throughout the year and
produce significant earnings in 2007. AP backlogs increased by $3.6
million to $9.3 million during the quarter, reflecting some success in
generating new business both in the traditional embassy market and in
other markets where high levels of protection are required.

    Public Safety & Justice ("PS&J") revenues declined to $10.6
million in the first quarter of 2007 compared to $11.8 million in the
first quarter of 2006. PS&J had a pre-tax loss of $0.2 million in the
first quarter of 2007 compared to break-even in the first quarter of
2006. Spending by PS&J's Tiburon business on its "Next Generation"
suite of .NET based software products, which is being fully expensed,
continues to impact current results and will impact future results.
During the first quarter PS&J very successfully took live one of the
largest installations they have ever undertaken. PS&J backlogs
declined slightly during the quarter, from $39.1 million at the
beginning of the quarter to $37.7 million at the end of the quarter.

    Integrated Electronic Systems ("IES") revenue was $5.0 million in
the first quarter of 2007 compared to $3.6 million in the first
quarter of 2006 and resulted in a doubling of pre-tax income to $0.4
million for the first quarter of 2007 compared to $0.2 million for the
first quarter of 2006. We have been advised that the Bureau of
Engraving and Printing ("BEP") will put its contract out to bid again
as a result of internal reorganizations. Results of this planned
re-bid are expected to become known late this year. We are optimistic
that it will be re-awarded to IES due to our outstanding performance.
IES' Quanta subsidiary continues to perform this BEP contract. IES'
newly combined Signami DCS business, made up of our Signami
acquisition and our DCS signals intelligence business, contributed
$1.8 million to IES' first quarter 2007 revenues. Signami DCS
continues to spend heavily on the refinement of its existing signals
intelligence product and on the new integrated platform of Signami and
DCS technologies - with the introduction of the new product later this
year we expect both revenues and margins in this business to improve
substantially.

    In the first quarter of 2007, corporate had a pre-tax loss of $0.3
million, compared to a pre-tax loss of $0.9 million in the first
quarter of 2006. This included $0.4 million of net interest cost in
the first quarter of 2007, down from $0.5 million in the first quarter
of 2006. Corporate expense was reduced despite incurring $0.2 million
on legal matters and $0.2 million on Audit/SOX (down from $0.4 million
in the first quarter of 2006) related costs in the first quarter of
2007. We ended the quarter with cash and marketable securities of
$24.2 million, working capital of $29.7 million, and only $1.5 million
of debt maturities prior to 2011.

    Company-wide backlogs were essentially flat during the first
quarter of 2007, ending the quarter at $117.1 million, down $0.2
million. This remains an unacceptably low level, however pipeline,
quoting, and bidding activity levels continue to be much higher than
in recent years.

    This press release contains unaudited financial information that
is not prepared in accordance with generally accepted accounting
principles (GAAP). Investors are cautioned that the non-GAAP financial
measures are not to be construed as an alternative to GAAP. The
Company's management uses earnings before interest, taxes,
depreciation and amortization, as adjusted for non-cash stock option
expense (EBITDAS), in its internal analysis of results of operations
and monitors EBITDAS to evaluate the Company's compliance with its
bank covenant for a fixed charge coverage ratio. Management believes
that EBITDAS and Income (Loss) Before Non-Cash Stock Option Expense is
useful to investors as a meaningful comparison between periods and as
an analysis of the critical components of the Company's results of
operations. Management also believes that EBITDAS is useful to
investors because it allows them to evaluate the Company's compliance
with its bank covenant for a fixed charge coverage ratio.
