          IASG Announces Alarm Contract Acquisitions and Obtains Board
            Approval to Acquire Commercial Alarm Monitoring Business


         Albany, New York (November 21, 2003) -- Integrated Alarm Services
Group, Inc. (Nasdaq: IASG) at a regularly scheduled board meeting on Thursday,
approved the acquisition of Lane Security, Inc., parent company of Protection
Service Industries, L.P. "PSI" of Rancho Cucamonga, California.

         PSI is a leading provider of commercial alarm monitoring services in
the western United States and also provides residential alarm monitoring in
these same markets. Total recurring monthly revenue "RMR" acquired will be
approximately $1,800,000, which represents the equivalent of 60,000 alarm
contracts. In addition, PSI also generates approximately $550,000 per month of
revenue, primarily associated with commercial alarm installation and related
service and inspection activities. Both Lane Industries, current owner of Lane
Security and IASG have received board approval to consummate the transaction.
IASG has completed its due diligence and the transaction is anticipated to be
completed in the next 15 business days pending execution of final purchase and
sale documents.

         Additionally, IASG announced the acquisition of 1,400 alarm monitoring
contracts, representing approximately $42,000 of RMR. Properties monitored by
these acquired contracts are primarily located in Tampa, Florida.

         Total consideration paid for these acquisitions will be approximately
$48 million.

         In announcing these transactions, Timothy M. McGinn, Chairman and CEO
of IASG, said, "We are pleased to have acquired the Tampa accounts and expect to
make further account acquisitions in the Tampa market. Further, the PSI
business, which is approximately 55% commercial and 45% residential, will
provide IASG with an opportunity to evolve from total reliance on residential
monitoring. The acquired PSI account base, located in California, Arizona and
New Mexico, will be serviced by the existing PSI infrastructure which will
become part of IASG."

         McGinn continued, "With the acquisition of PSI, account equivalent
additions since the Company's IPO will total 74,600. These contract acquisitions
strengthen our Company's presence in important targeted geographic markets with
solid alarm industry demographics. The PSI acquisition, when completed, will put
IASG solidly in a key commercial market - the western United States."
