SENTRY TECHNOLOGY CORPORATION
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The increase in CCTV revenues and decline in SentryVision(R) during the current
year periods is primarily related to the decision by one of the Company's major
customers to purchase conventional CCTV for the bulk of its security product
orders for 1999. Also, the second quarter of 1998 included a SentryVision(R)
sale to a multi-level parking garage which accounted for $1.2 million.

Cost of sales were 57% and 55% of total revenues in the three and six month
periods ended June 30, 1999 compared to 44% and 48% in the same periods in the
previous year. The increase in the percentage in the current year periods as
compared to the previous year periods is a result of a combination of factors
including: (i) a higher percentage of revenues resulting from sales to the
Company's distributors and to Sensormatic, both of which carry lower margins
than direct customer sales; (ii) increased sales of CCTV products which result
in higher product costs than the SentryVision(R) product line; and (iii) higher
EAS product costs due to continued training costs and lower machine output
levels on equipment damaged in transit from the Puerto Rico plant.

Customer service expenses were 22% and 2% lower in the second quarter and first
six months of 1999 as compared to the second quarter and first six months of
1998 due primarily to a lower number of SentryVision(R) installations in the
current periods which require more labor than installations of the Company's
other products.

Selling, general and administrative expenses were lower in both the three month
and six month periods ended June 30, 1999 as compared to the same periods of the
previous year primarily as a result of the savings through the consolidation of
facilities.

Research and development costs remained fairly constant in all periods
presented. The primarily emphasis in the current year has been directed towards
manufacturing improvements related to the move from Puerto Rico to New York and
improvements to the SentryVision(R)system.

Net interest expense for the second quarter and first six months of 1999
increased by $8,000 and $47,000, repectively, over the same periods of 1998. The
increase is due to higher net borrowings under the Company's revolving credit
agreement.

During the first quarter of 1999, the Company sold its Puerto Rico manufacturing
facility and Illinois design center for net cash proceeds of approximately $2.2
million which resulted in a net gain on the sale of $503,000.

Sentry's income taxes in the first half of 1998 represent a provision on the
cumulative earning of the Puerto Rico manufacturing operations which were closed
at the end of 1998. Due to net losses, Sentry has not provided for income taxes
in any other periods presented.

As a result of the foregoing, Sentry had a net loss of $988,000 and $2,307,000
in the quarter and six month period ended June 30, 1999 as compared to a net
loss of $491,000 and $2,438,000 in the quarter and six months ended June 30,
1998.

Preferred stock dividends of $333,000 and $654,000 have been recorded in the
second quarter and first six months of 1999 as compared to $317,000 and $623,000
in the second quarter and first six months of 1998. Dividends accrued through
February 12, 1999 were paid-in-kind as of that date. In connection with the
waiver of certain financial covenants under the Company's agreement with its
commercial lender, the Company is restricted from paying cash dividends,
including the cash dividend on its Class A Preferred Stock which would otherwise
be payable in August of 1999. Under the terms of the Class A Preferred Stock,
the dividends will cumulate and Class A Preferred Stockholders, voting as a
class, will be entitled to elect two additional directors to the Company's
Board.

LIQUIDITY AND CAPITAL RESOURCES AS OF JUNE 30, 1999

The Company has funded its operations and capital expenditures through
borrowings under its revolving credit facility and use of existing cash. The
cash proceeds of $2.2 million from the sale of certain facilities, noted above,
were used to reduce borrowings under the revolving credit facility during the
first quarter.

The Company anticipates that current cash reserves, cash generated by operations
and financing arrangements should be sufficient to meet the Company's working
capital requirements as well as future capital expenditure requirements for the
next twelve months.


YEAR 2000 UPDATE

Many existing computer programs were designed and developed without considering
the upcoming change in the century, which could lead to the failure of computer
applications or create erroneous results by or at the Year 2000. On January 1,
2000, any computer system or other equipment using date sensitive software which
uses only two digits to represent the year may recognize "00" as the year 1900
rather than the year 2000. This could result in a system failure or
miscalculations causing disruptions of operations, including among other things,
a temporary inability to process transactions, send invoices, or engage in
similar activities.

Recognizing the potential impact, the Company began actively resolving its Year
2000 compliance issues in early 1997. Using internal and external resources, the
Company analyzed and assessed its business systems, including computer systems,
PC's and network hardware, telephone systems, production process controllers,
access control, office equipment and the product it sells.

Upgrades to both mid-range and network computer hardware, operating systems and
related infrastructures have been completed and are now Year 2000 compliant. All
critical application software has been reviewed and Year 2000 compliant versions
have been obtained. The Company has completed the process of retrofitting custom
modifications to the upgraded versions. All applications with forward scheduling
impact are now considered to be Year 2000 compliant. The Company believes its
manufactured products are Year 2000 compliant.

The cost of becoming compliant is not expected to exceed $300,000 and
approximately one half has been incurred to date. The remaining costs relate
primarily to hardware upgrades to the Company's PC's and telephone systems which
will be completed by the third quarter of 1999. There can be no assurance that
the Company will not incur unanticipated costs or that it will be able to
successfully address all Year 2000 issues.

The impact of the Year 2000 issue on the Company will also be affected by the
Year 2000 readiness of its business partners, customers, suppliers and vendors
and providers of facilities, equipment and services. Failure by these third
parties to be Year 2000 compliant may adversely affect, among other things, the
Company's production, revenue and the timing of cash receipts. The Company has
begun to make inquiries of such third parties in this regard and based on the
responses to these inquiries, the Company will decide to what extent, if any, a
contingency plan should be developed. To date, however, the Company has received
only preliminary feedback from such third parties and has not independently
confirmed any information received from such third parties with respect to Year
2000 issues. As such, there can be no assurance that such third parties will
address the Year 2000 issue and complete their Year 2000 conversion in a timely
fashion or will not suffer a Year 2000 business disruption that may adversely
affect the Company's business.
