SENTRY  TECHNOLOGY  CORPORATION
NOTES  TO  CONDENSED  CONSOLIDATED  FINANCIAL  STATEMENTS
JUNE  30,  2004


NOTE  A  --  Basis  of  Presentation
- ------------------------------------
The  consolidated  financial  statements  include the accounts of Sentry and its
majority-owned  subsidiaries.  All  intercompany  accounts and transactions have
been  eliminated  in  consolidation.

The accompanying unaudited condensed consolidated financial statements have been
prepared  in  accordance  with  accounting  principles generally accepted in the
United  States  of  America  for  interim  financial  information  and  with the
instructions  to  Form  10-QSB.  Accordingly,  they  do  not  include all of the
information  and  footnotes required by accounting principles generally accepted
in  the  United  States  of  America  for  complete financial statements. In the
opinion of management, all adjustments (consisting of normal recurring accruals)
considered  necessary  for  a  fair  presentation  have  been included.  Interim
results are not necessarily indicative of the results that may be expected for a
full  year.  These  financial  statements should be read in conjunction with the
audited consolidated financial statements and notes thereto included in Sentry's
Annual  Report to Stockholders on Form 10-KSB for the fiscal year ended December
31,  2003,  as  filed  with  the  Securities  and  Exchange  Commission.

Certain prior period amounts have been reclassified to conform to current period
presentation.


NOTE  B  --  Capital  Transactions  and  ID  Systems  Acquisition
- -----------------------------------------------------------------
Over  the  last  several years, our largest shareholder, Dialoc ID Holdings B.V.
("Dialoc")  was  not able to provide us with additional financial support.
On  April  19,  2004,  Dialoc sold 39,066,927 Sentry common shares (representing
approximately  46%  of  the  total issued and outstanding shares of Sentry) to a
group of investors.  Of the group, Saburah Investments Inc. ("Saburah") acquired
22,758,155  shares,  Mr.  Robert  Furst 14,554,386 shares and Dr. Morton Roseman
1,754,386  shares.  Mr. Peter Murdoch, President, CEO and Director of Sentry, is
the  owner  of  Saburah.  Mr.  Furst  is also a long-standing member of Sentry's
Board of Directors.  As a result of this transaction, Messers Angel and de Nood,
Principals  of  Dialoc,  resigned  from  Sentry's  Board  of  Directors.

In  addition  to  the  purchase of Sentry's common shares, Saburah also acquired
100% of ID Security Systems Canada, Inc. and ID Systems USA Inc. ("ID Systems").
The price paid to Dialoc by Saburah and Murdoch for Sentry and ID Systems shares
in  cash,  debt assumption and other consideration is approximately $3.6 million
plus the surrender of Murdoch's 15% interest in Dialoc.  Saburah has also agreed
to  make  a  payment  to  Dialoc  in the future equal to approximately 6% of any
payment  it  receives from Checkpoint Systems Inc. ("Checkpoint") resulting from
litigation  brought  by  ID  Canada  against  Checkpoint.


On  April  30, 2004, Sentry purchased from Saburah Investments, Inc., an Ontario
corporation,  all  of  the  outstanding  common shares and Series "A" preference
shares  of  ID  Security Systems Canada Inc., an Ontario corporation, and all of
the  outstanding  capital  stock  of  ID  Systems  USA,  Inc.,  a  Pennsylvania
corporation  (collectively, "ID Systems"). ID Systems is a Toronto based company
engaged  in  anti-shoplifting  technology,  security  labeling,  radio frequency
identification  (RFID),  access control and library security. Sentry acquired ID
Systems  from Saburah in exchange for 30,000,000 Sentry common shares. The price
paid  per  Sentry  share  for  the  securities  of  ID  Systems  was  valued  at
approximately $0.11. A special committee of Sentry's Board of Directors received
an  opinion from Corporate Valuation Services confirming that the price paid for
the  acquisition  of  ID  Systems  was  fair  from  the  point of view of Sentry
shareholders.  As part of the purchase agreement, the proceeds of the ID Systems
litigation settlement will be distributed to the former ID Systems shareholders.
However  Saburah  and  Sentry  have  agreed  that  Sentry may require Saburah to
purchase  additional  Sentry common shares under certain circumstances. Sentry's
Board  of  Directors  and  shareholders owning a majority of Sentry common stock
approved  the  acquisition  of  ID  Systems.


Other  benefits  flowing to Sentry/ID Systems via the purchase of ID Systems are
as  follows:

- -     ID  Systems  and Sentry continue as the exclusive distributor in North and
South  America  for  a  period  of  five years for all Dialoc products including
Laserfuse  radio  frequency  security  labels  and  all  RFID  products.

- -     Dialoc  becomes  the  exclusive  distributor  in Europe and Asia of labels
manufactured  by  ID  Systems'  security  label manufacturing subsidiary, Custom
Security  Industries  Inc.  ("CSI").

- -     CSI  acquires  the right to purchase Laserfuse raw material for processing
into  finished  security labels in its Toronto plant in order to reduce the cost
of  production.


- -     CSI acquires the option to purchase a non-exclusive license to manufacture
complete  Laserfuse  security  labels  for  a  period of 10 years subject to the
payment  of  $500,000  and  a  running  royalty  of  $0.001  per  label.

- -     Dialoc  will  continue  to  be  a dealer for Sentry products in Europe and
Asia.

The  purchase  price  of  the  ID Systems acquisition  was  as  follows:

The  Company  is  still  in  the  process  of  obtaining  final  support for the
valuations  of certain intangible assets; accordingly allocation of the purchase
price  is  subject  to modification in the future.  Any such modification is not
expected  to  be  significant.  On  an  ongoing  basis, Sentry will evaluate the
carrying  value  versus the discounted cash benefit expected to be realized from
the  performance  of  the underlying operations and adjust for any impairment in
value.

NOTE  C  --  Convertible  Debenture
- -----------------------------------
On  April  30,  2004,  Sentry  entered  into  a  $2,000,000  secured convertible
debenture  with  Brascan  Technology Fund ("Brascan"), an alternative investment
fund  established  by  Brascan  Asset  Management,  to  invest  in  early stage,
technology-based  companies  with  high  growth  potential.

Key  terms  of  the  transaction  are  as  follows:

- -     Four-year  term.
- -     Interest  rate  of  8%.
- -     Redeemable  at  Sentry's  option  after  18  months.
- -     Conversion  price equal to the market price, at time of conversion, less a
      discount  of  30%  with  a  maximum  conversion  price  of  $0.12  per
      share.
- -     Conversion is at the option of Brascan when market share price is
      equal  to  or  greater  than  $0.17  per  share  or with the
      approval  of  Sentry's  Board  of  Directors when the market
      share  price  is  less  than  $0.17  per  share.
- -     Sentry  will  provide  most  favored pricing to all Brascan affiliates and
      expects  to be a supplier of security and identification products to the
      Brascan affiliates.
- -     Brascan  was  issued warrants for 5,000,000 shares of Sentry common stock,
      priced  at  $0.15  per  share,  exercisable  anytime within the next four
      years.
- -     Brascan  is  entitled  to  one seat on Sentry's Board of Directors or will
      participate  as  an  observer.

The  Debenture is secured by a general security interest over all the assets and
properties of Sentry.  The amount is subordinate to the existing CIT and Bank of
Montreal  credit  facilities.

The  proceeds  of  the financing, to be used primarily for working capital, were
allocated  between  the debenture ($1,835,000) and the warrants ($165,000) based
on  their  respective  fair values in accordance with EITF 00-27 (Application of
Issue 98-5 to Certain Convertible Instruments).  The difference between the face
value  of  the debenture and the allocated value will be charged to interest and
financing  expenses  over  the  term  of  the  debenture.

Certain  other  warrants  to  purchase  425,000 shares of Sentry common stock at
exercise prices ranging from $0.18 to $0.20 per share were issued in conjunction
with  the convertible debenture.  The warrants are exercisable over one to three
years.  The fair value of these warrants ($49,000) will be charged to operations
over  the  life  of  the  warrants.

As  a  condition  of  the  financing,  Sentry  also  acquired  ID  Systems.

Sentry's  Board of Directors and shareholders owning a majority of Sentry common
stock  approved  the  transaction  with  Brascan.

Sentry  requires  liquidity  and  working  capital  to  finance  increases  in
receivables  and  inventory  associated  with sales growth, payments to past due
vendors  and,  to a lesser extent, for capital expenditures.  We had no material
capital  expenditure or purchase commitments as of June 30, 2004.  We anticipate
that  current  cash reserves, cash generated by the operations of Sentry and its
new  ID  Systems  subsidiaries  and  the  financing  provided  by  the  Brascan
transaction  and  sale  of  stock  to  Saburah  will  be adequate to finance the
Company's  anticipated  working  capital  requirements as well as future capital
expenditure  requirements  for  at  least  the  next  twelve  months.


NOTE  D  --  Inventories
- ------------------------
Inventories  consist  of  the  following:

of June 30, 2004 and December 31, 2003, respectively and have been included as a
component  of  the  above  amounts.







NOTE  E  --  Credit  Facilities
- -------------------------------
On April 30, 2004, Sentry's subsidiary, ID Security Systems Canada Inc., entered
into  credit  facilities  with  Bank  of  Montreal,  replacing its former credit
facility.  Facility  1  is a Canadian $1.5 million (U.S. $1.1 million) Overdraft
Lending  Facility, which is subject to certain limitations based on a percentage
of  eligible  accounts  receivable  and inventories as defined in the agreement.
Interest  on  the  overdraft facility is payable monthly at the Bank of Montreal
commercial  prime  lending  rate  (3.75%  at  June 30, 2004), plus 1% per annum.
Facility  2  is  a Canadian $250,000 (U.S. $187,000) Non-Revolving Demand Credit
facility  incurred  to  refinance an existing term loan with a previous lender.
Principal  payments  of  Canadian  $6,945  plus  interest are payable monthly in
arrears.  Borrowings  under  these  facilities  are  secured by the assets of ID
Systems.  At  June  30,  2004, approximately U.S. $974,000 was outstanding under
the  Bank  of  Montreal  facilities.



NOTE  F  --  Related  Party  Transactions
- -----------------------------------------
On  March  27,  2002,  Peter  Murdoch,  our President and CEO, exercised a stock
option  for  two  million  shares of Sentry common stock at an exercise price of
$0.06 per share, which was paid for through the issuance of a promissory note in
the  amount  of  $120,000.  The  principal of the note was secured by the option
shares  and was repayable no later than January 8, 2006.  The note bore interest
at  prime  less .75%.  Mr. Murdoch satisfied the note and accrued interest as of
March  31,  2004.  The  note  had been reflected as a reduction of shareholders'
equity  on  the  balance  sheet  as  of  December  31,  2003.

On  January 22, 2004, Robert Furst, a Sentry Director, made a bridge loan to the
Company  in  the  amount of $100,000.  The interest rate on the loan was 15% per
annum  and  the  loan  was  due  on  or  before  April  30, 2004.  As additional
consideration  for  the  loan,  Mr. Furst received a warrant to purchase 300,000
shares  of  Sentry  common  stock  at  a price of $0.17 per share, which was the
market  price  on  the  date  of  grant (valued at $3,000).  The warrant expires
January  21,  2009.  The  note  was  repaid  in  full  on  April  30,  2004.



NOTE  G  --  Earnings  Per  Share
- ---------------------------------
The  earnings  per  share  calculations (basic and diluted) at June 30, 2004 and
2003  are  based  upon  the weighted average number of common shares outstanding
during  each  period.  There  are  no  reconciling  items  in  the  numerator or
denominator  of  the  earnings  per  share calculations in either of the periods
presented.  Options  to  purchase 1,499,948 and 1,615,912 shares of common stock
with  a  weighted  average exercise price of $0.59 and $0.57 were outstanding at
June  30, 2004 and 2003, but were not included in the computation of diluted net
loss  per  share  because  their  effect  would  be  antidilutive or immaterial.

The  Company  accounts  for  stock-based awards to employees using the intrinsic
value  method  in  accordance  with  Accounting Principles Board Opinion No. 25,
"Accounting  for  Stock  Issued  to  Employees."

SFAS  No.  123, Accounting for Stock-Based Compensation, requires the disclosure
of  pro forma net income and earnings per share had the Company adopted the fair
value  method  as  of the beginning of fiscal 1995. Under SFAS No. 123, the fair
value of stock-based awards to employees is calculated through the use of option
pricing  models,  even  though  such  models were developed to estimate the fair
value  of  freely  tradable,  fully  transferable  options  without  vesting
restrictions,  which  significantly  differ  from  the  Company's  stock options
awards. These models also require subjective assumptions, including future stock
price  volatility  and  expected  time  to  exercise,  which  greatly affect the
calculated values. No options were granted in 2004 or 2003. The weighted average
fair  value  of  the  options  granted  for  the year ended December 31, 2001 is
estimated  at  $0.05,  using  the  Black-Scholes  option  pricing model with the
following  weighted  average  assumptions:  expected  life  of five years; stock
volatility,  147%  in  2001;  risk  free  interest  rates,  4.8% in 2001, and no
dividends  during  the  expected term. The Company's calculations are based on a
multiple option valuation approach and forfeitures are recognized as they occur.
If  the  computed  fair  values  of  the  post 1995 awards had been amortized to
expense  over  the vesting period of the awards, pro forma net income attributed
to  common  shareholders  would  have  been  as  follows:
















                                                        Three Months Ended     Six Months Ended

The  fair  value  of each option granted is estimated on the date of grant using
the Black-Scholes option-pricing model.  No options were granted in the three or
six-month  periods  ended  June  30,  2004  or  2003.



NOTE  H  --  Subsequent  Event
- ------------------------------
On August 1, 2004, ID Systems and Checkpoint entered into a settlement agreement
effective  July  30,  2004,  pursuant  to  which Checkpoint agreed to pay $19.95
million, in full and final settlement of claims covered by antitrust litigation.
Payment  in  full  was  received  on  August  5,  2004.  As provided when Sentry
purchased  ID  Systems,  the  proceeds  of the settlement will be distributed to
former  shareholders  of  ID  Systems,  after  payment  of  litigation  fees and
expenses.  The  agreement  includes  mutual  releases  between  the  parties for
complaints  arising  from  activities prior to the date of the agreement, except
for  any  contractual obligations and any future claims for patent, copyright or
trademark  infringement.  The  agreement  is  not  an  acknowledgement  of  any
wrongdoing  or  liability  by  either party. A Stipulation of Dismissal has been
filed  with  the  Third  Circuit  Court of Appeals to finally conclude the legal
proceedings.

While  Sentry  did  not obtain an interest in the litigation settlement, Saburah
and  Sentry  have  agreed that Sentry may require Saburah to purchase additional
Sentry  common shares equal to approximately 4.5% of any amount received (net of
legal  fees  and  expenses) from Checkpoint. The price per share has been set at
80%  of  the  previous  20 days trading average prior to the announcement of the
settlement.  Sentry's  Board of Directors has exercised this option and based on
the settlement amount, will sell to Saburah approximately 4.8 million shares for
approximately  $640,000.  Sentry and its subsidiaries also expects to receive an
additional  $760,000  through  the repayment of debt incurred by Dialoc prior to
the  ID Systems acquisition and the reimbursement for litigation expenses, which
are  recorded  as  assets  on  the  balance  sheet  as  of  June 30, 2004. These
transactions,  totaling $1.4 million, represent the total cash flowing to Sentry
directly  and  indirectly  as  a  result  of  the  Checkpoint  lawsuit.


After the acquisition of ID Systems and sale of additional shares as a result of
the  litigation  settlement, Sentry will have 120,559,724 shares of common stock
outstanding.  Mr.  Murdoch,  directly  or  indirectly  through  his ownership of
Saburah,  will  own  or control 49.5% of the outstanding common stock of Sentry.

Results  of  Operations:
- ------------------------

On  April  30,  2004, Sentry purchased from Saburah Investments, Inc. all of the
outstanding  common  shares  and  Series  "A"  preference  shares of ID Security
Systems Canada Inc., and all of the outstanding capital stock of ID Systems USA,
Inc. (collectively, "ID Systems"). ID Systems is a Toronto based company engaged
in  anti-shoplifting  technology,  security  labeling,  radio  frequency
identification  (RFID),  access  control  and  library  security.  Our condensed
consolidated  statements  of  operations include the revenues and expenses of ID
Systems  from  May  1,  2004.


Consolidated  revenues  were  82%  and  22%  higher in the quarter and six month
period  ended  June 30, 2004 than in the quarter and six month period ended June
30,  2003.  ID Systems revenues for the two months ended June 30, 2004 were $0.9
million.  Our  backlog  of  orders,  which  we expect to deliver within the next
twelve  months,  increased  to $4.1 million at June 30, 2004 as compared to $3.4
million  at  June 30, 2003.  Total revenues for the periods presented are broken
out  as  follows:

All of the increase in sales of EAS products in the second quarter and first six
months  of  2004 was attributable to ID Systems sales which totaled $0.9 million
of  the  respective  totals  as  compared to the same periods in the prior year.
Sentry's  historical  comparative  sales  of EAS products decreased in both 2004
periods  presented.  While  there  was  an  increase in CCTV sales in the second
quarter  of 2004 as a result of higher sales to Lowe's Home Centers, there was a
decrease  in the six months of 2004 is a result of lower sales to two customers.
In the first half of 2003, we had sales of $0.6 million to Home Depot, which did
not  repeat  in  2004  and  we  lost  $0.6  million  in  revenues in 2004 from a
significant  customer  that  decided  to  source  their CCTV purchases directly.
Direct sales of SentryVision  increased in 2004, including sales to Wal-Mart UK,
Target,  Reno  Depot  and Lane Limited.  Service revenues and other increased in
the  second  quarter  primarily  as  a  result  of  higher revenue from CCTV and
SentryVision  installations  than  in the second quarter and first six months of
2003.

Cost  of  sales  were 53% of total sales in both the three and six month periods
ended  June  30,  2004  compared to 56% and 65% in the same periods of the prior
year.  We  have outsourced all significant manufacturing operations beginning in
the  second  quarter of 2003, resulting in lower product costs.  The decrease in
the  cost  of  sales percentage in the first six months of 2004 is primarily the
result of the elimination of the charge to cost of sales of under absorbed fixed
overhead  costs due to the termination of in-house manufacturing and the move to
a  smaller  facility.



The  increase  in  customer service expenses in the second quarter and first six
months  of  2004  is a primarily a result of higher sales of systems we install.
We have decreased the number of customer service employees and increased the use
of  outside service contractors in order to better manage our total net customer
service  costs  during  fluctuations in activity levels from quarter to quarter.
However,  our  efforts  were  hampered  somewhat  by our inability to maintain a
proper  level  of  service  parts  due  to inadequate trade credit and financial
resources during the first six months of 2004, which resulted in inefficiencies.
As  a  result  of  our  recent financing, we have recently restocked our service
parts  inventory  enabling  us to deliver service in a more timely and efficient
manner.

Selling,  general  and  administrative  expenses  were 43% and 17% higher in the
three  and  six  month  periods  ended  June  30, 2004 when compared to the same
periods  of  the  previous  year primarily as a result of the ID Systems merger.
However,  as  a  percent  of  total  revenues,  total  costs  decreased.

We  dedicated  the same amount to research and development in the second quarter
and  first  six months of 2004 when compared to the second quarter and first six
months  of  2003.

As  a  result of the restructuring of operations, the increase in sales activity
levels  and the merger with ID Systems, we were able to show operating income of
$120,000  and  $53,000 in the three and six month periods ended June 30, 2004 as
compared  to  operating  losses  of $188,000 and $492,000 in the same periods of
2003.

Total interest and financing costs decreased in the second quarter and first six
months  of  2004, principally as a result of lower capital lease interest due to
the  cancellation of the sale and leaseback agreement on our former headquarters
facility.

In  the  second  quarter  of  2003,  the  Company entered into a settlement with
certain  of  its  vendors  for  past due obligations which resulted in a gain of
approximately  $522,000  (net  of  $348,000  income  taxes) which represents the
difference  between  the  amounts due before the settlement and the total amount
payable, including the value of the common stock, as a result of the settlement.

In  2004, the income tax provision results from taxable income of our ID Systems
subsidiary, which cannot be offset by Sentry's net operating loss carryforwards.
In  2003, the $348,000 income tax provision recognized on the extraordinary gain
was  offset  by  an  equivalent  income  tax  benefit generated from the current
period's  loss  from  operations  and  the  utilization  of  net  operating loss
carryforwards.

As a result of the foregoing, Sentry had net income of $12,000 and a net loss of
$180,000  in the quarter and first six months ended June 30, 2004 as compared to
net profits of $530,000 and $36,000 in the quarter and six months ended June 30,
2003.

Liquidity  and  Capital  Resources  as  of  June  30,  2004

In  the second quarter of 2003, to address our reduced revenue levels, decreased
financial  position  and  recurring  operating  losses,  our  Board of Directors
approved  a  2003  restructuring  plan  to  strengthen  the  Company's operating
efficiencies and to better align its operations with current economic and market
conditions.  We  were  successful  in  implementing many changes to our business
plan  during  2003  including  the  downsizing  of  operations and relocation to
smaller  facilities,  the  negotiations with past due trade creditors and former
landlord,  the  outsourcing  of  manufacturing  and the expansion of our Service
Partner  program  to  augment  service  and  installations.  The  successful
implementation  of  this  restructuring has resulted in substantial gross margin
improvements  and  reductions  in operating  expenses  beginning  after  the
first  quarter  of  2003.

Over  the  last  several years, our largest shareholder, Dialoc ID Holdings B.V.
("Dialoc")  was  not  able  to provide us with additional financial support.  On
April  19,  2004,  Dialoc  sold  39,066,927  Sentry  common shares (representing
approximately  46%  of  the  total issued and outstanding shares of Sentry) to a
group of investors.  Of the group, Saburah Investments Inc. ("Saburah") acquired
22,758,155  shares,  Mr.  Robert  Furst 14,554,386 shares and Dr. Morton Roseman
1,754,386  shares.  Peter  L. Murdoch, President, CEO and Director of Sentry, is
the  owner  of  Saburah.  Mr.  Furst  is also a long-standing member of Sentry's
Board of Directors.  As a result of this transaction, Messers Angel and de Nood,
Principals  of  Dialoc,  have  resigned  from  Sentry's  Board  of  Directors.


In  addition  to  the  purchase of Sentry's common shares, Saburah also acquired
100% of ID Security Systems Canada, Inc. and ID Systems USA Inc. ("ID Systems").
ID  Systems  is  a Toronto based company engaged in anti-shoplifting technology,
security  labeling,  radio  frequency  identification (RFID), access control and
library  security.  The  price  paid to Dialoc by Saburah and Murdoch for Sentry
and  ID  Systems  shares  in  cash,  debt  assumption and other consideration is
approximately  $3.6  million  plus  the  surrender  of Murdoch's 15% interest in
Dialoc.  Saburah has also agreed to make a payment to Dialoc in the future equal
to  approximately  6%  of  any  payment it receives from Checkpoint Systems Inc.
resulting  from  litigation  brought  by  ID  Canada  against  Checkpoint.

On  April  30, 2004, Sentry purchased from Saburah Investments, Inc., an Ontario
corporation,  all  of  the  outstanding  common shares and Series "A" preference
shares  of  ID  Security Systems Canada Inc., an Ontario corporation, and all of
the  outstanding  capital  stock  of  ID  Systems  USA,  Inc.,  a  Pennsylvania
corporation  (collectively,  "ID  Systems").  ID  Systems  is  a  Toronto  based
company  engaged  in  anti-shoplifting  technology,  security  labeling,  radio
frequency  identification  (RFID),  access control and library security.  Sentry
acquired  ID  Systems  from  Saburah  in  exchange  for 30,000,000 Sentry common
shares.  The  price  paid  per Sentry share for the securities of ID Systems was
valued  at  approximately  $0.11.  A  special  committee  of  Sentry's  Board of
Directors  received an opinion from Corporate Valuation Services confirming that
the price paid for the acquisition of ID Systems was fair from the point of view
of  Sentry  shareholders.  Sentry's Board of Directors and shareholders owning a
majority  of  Sentry  common  stock  approved  the  acquisition  of  ID Systems.


The  purchase  price  of  the  acquisition  was  approximately  $3.4  million
representing $3.3 million in the value of Sentry common stock issued and $0.1 in
transaction  expenses.  Sentry  will acquire $1.8 million in net tangible assets
and  assign the remaining $1.6 million to goodwill. (See Note B to the condensed
consolidated  financial  statements).  On an ongoing basis, Sentry will evaluate
the  carrying  value of the goodwill versus the discounted cash benefit expected
to  be realized from the performance of the underlying operations and adjust for
any  impairment  in  value.

Other  benefits  flowing to Sentry/ID Systems via the purchase of ID Systems are
as  follows:

- -     ID  Systems  and Sentry continue as the exclusive distributor in North and
      South  America  for  a  period  of  five years for all Dialoc products
      Including Laserfuse  radio  frequency  security  labels  and  all  RFID
      products.

- -     Dialoc  becomes  the  exclusive  distributor  in Europe and Asia of labels
      manufactured  by  ID  Systems'  security  label manufacturing subsidiary,
      Custom Security  Industries  Inc.  ("CSI").

- -     CSI  acquires  the right to purchase Laserfuse raw material for processing
      into  finished  security labels in its Toronto plant in order to reduce
      the cost of  production.

- -     CSI acquires the option to purchase a non-exclusive license to manufacture
      complete  Laserfuse  security  labels  for  a  period of 10 years subject
      to the payment  of  $500,000  and  a  running  royalty  of  $0.001  per
      label.

- -     Dialoc  will  continue  to  be  a dealer for Sentry products in Europe and
      Asia.

On  April  30,  2004, ID Systems entered into new credit facilities with maximum
availability  of  Canadian  $1.75  million  (U.S. $1.3 million) with the Bank of
Montreal.   The  facilities  provide  working  capital  for  ID  Systems and all
borrowings  are  secured  by  the  assets  of  ID  Systems.

We continued to pursue additional debt or equity financing through our financial
advisors  and  on  April  30,  2004,  Sentry  entered  into a $2,000,000 secured
convertible  debenture  with Brascan Technology Fund ("Brascan"), an alternative
investment  fund  established  by  Brascan  Asset Management, to invest in early
stage,  technology-based  companies with high growth potential.  The proceeds of
the  financing  will  be  used  primarily  for  working  capital.

Key  terms  of  the  transaction  are  as  follows:

- -     Four-year  term.
- -     Interest  rate  of  8%.
- -     Redeemable  at  Sentry's  option  after  18  months.
- -     Conversion  price equal to the market price, at time of conversion, less a
      discount  of  30%  with  a  maximum  conversion  price of $0.12 per share.
- -     Conversion is at the option of Brascan when market share price is equal to
      or  greater  than  $0.17  per  share  or  with the approval of Sentry's
      Board of Directors when  the  market  share  price  is  less  than  $0.17
      per  share.
- -     Sentry  will  provide  most  favored pricing to all Brascan affiliates and
      expects  to be a supplier of security and identification products to the
      Brascan affiliates.
- -     Brascan  was  issued warrants for 5,000,000 shares of Sentry common stock,
      priced  at  $0.15  per  share,  exercisable  anytime within the next four
      years.
- -     Brascan  is  entitled  to  one seat on Sentry's Board of Directors or will
      participate  as  an  observer.

The  Debenture is secured by a general security interest over all the assets and
properties of Sentry.  The amount is subordinate to the existing CIT and Bank of
Montreal  credit  facilities.

Sentry  also  acquired  ID  Systems  as  a  condition  of  the  financing.

Sentry's  Board of Directors and shareholders owning a majority of Sentry common
stock  approved  the  transaction  with  Brascan.

As  of  June 30, 2004, we had borrowings of approximately $1.9 million with CIT,
the  maximum  amount  available  under  the  revolving  credit facility and $1.0
million  with the Bank of Montreal.  Through the first half of 2004, most of our
trade  vendors  continued  to  require  cash  in advance or COD payments for our
purchases.  Prior  to the Brascan financing, we had to supplement our borrowings
under  the  CIT  credit facility with expensive purchase order financing through
EPK Financial Corporation ("EPK").  As a result of the Brascan financing, during
the  second  quarter of 2004, we repaid all amounts owed to EPK and discontinued
our  use  of  this  facility.

On August 1, 2004, ID Systems and Checkpoint entered into a settlement agreement
effective  July  30,  2004,  pursuant  to  which Checkpoint agreed to pay $19.95
million,  in  full  and  final  settlement  of  claims  covered by the antitrust
litigation.  Payment  in  full  was received on August 5, 2004. As provided when
Sentry  purchased ID Systems, the proceeds of the settlement will be distributed
to  former  shareholders  of  ID  Systems,  after payment of litigation fees and
expenses.  The  agreement  includes  mutual  releases  between  the  parties for
complaints  arising  from  activities prior to the date of the agreement, except
for  any  contractual obligations and any future claims for patent, copyright or
trademark  infringement.  The  agreement  is  not  an  acknowledgement  of  any
wrongdoing  or  liability  by  either party. A Stipulation of Dismissal has been
filed  with  the  Third  Circuit  Court of Appeals to finally conclude the legal
proceedings.

While  Sentry  did  not obtain an interest in the litigation settlement, Saburah
and  Sentry agreed that Sentry may require Saburah to purchase additional Sentry
common  shares  equal to approximately 4.5% of any amount received (net of legal
fees  and  expenses)  from Checkpoint. The price per share was set at 80% of the
previous  20  days  trading average prior to the announcement of the settlement.
Sentry's  Board  of  Directors  has  exercised  this  option  and  based  on the
settlement  amount,  will  sell  to Saburah approximately 4.8 million shares for
$640,000.  Sentry  also  expects to be reimbursed for legal costs advanced by ID
Systems,  as  well as for loans and trade receivables of approximating $760,000,
which  are  recorded  as  assets on the balance sheet as of June 30, 2004. These
transactions,  totaling  $1.4  million,  represent  the  cash  flowing to Sentry
directly  and  indirectly  as  a  result  of  the  Checkpoint  lawsuit.


After the acquisition of ID Systems and sale of additional shares as a result of
the  litigation  settlement, Sentry will have 120,559,724 shares of common stock
outstanding.  Mr.  Murdoch,  directly  or  indirectly  through  his ownership of
Saburah,  will  own  or control 49.5% of the outstanding common stock of Sentry.


We  will  require  liquidity  and  working  capital  to  finance  increases  in
receivables  and  inventory  associated  with sales growth, payments to past due
vendors  and,  to a lesser extent, for capital expenditures.  We had no material
capital  expenditure or purchase commitments as of June 30, 2004.  We anticipate
that  current  cash reserves, cash generated by the operations of Sentry and its
new  ID  Systems  subsidiaries, as well as the financing provided by the Brascan
transaction  and  the  sale  of stock to Saburah will be adequate to finance the
Company's  anticipated  working  capital  requirements as well as future capital
expenditure  requirements  for  at least the next twelve months.  As a result of
the  financing,  Sentry  will no longer need to use the expensive purchase order
financing  provided by EPK in order to finance inventory purchases.  As well, by
agreement  with  CIT,  the  previous  monthly  costs  for  outside  management
consultants  were  also  eliminated  as  of  May  2004.

Item  3.  Controls  and  Procedures

As  of  the  end  of  the  period  covered  by  this  report,  Sentry Technology
Corporation  carried  out  an  evaluation,  under  the  supervision and with the
participation  of  the  Company's  management,  including  the  Company's  Chief
Executive  Officer  and  Chief  Financial  Officer,  of the effectiveness of the
design  and  operation  of  the  Company's  disclosure  controls  and procedures
pursuant  to Rule 13a-15 of the Securities and Exchange Act of 1934.  Based upon
that  evaluation,  the  Chief  Executive  Officer  and  Chief  Financial Officer
concluded that the Company's disclosure controls and procedures are effective in
timely  alerting  them  to  material  information related to the Company that is
required to be included in Sentry Technology Corporation's periodic SEC filings.

There  has  been  no  change  in  the  Company's internal control over financial
reporting during the period covered by this report that has materially affected,
or  is  reasonable  likely  to materially affect, the Company's internal control
over  financial  reporting.

Item  1.  Legal  Proceedings

ID  Security  Systems  Canada  Inc.  versus  Checkpoint  Systems,  Inc.

On May 24, 2002, the jury in the Civil Action No. 99-CV-577 in the United States
District  Court  for the Eastern District of Pennsylvania, filed by plaintiff ID
Security  Systems  Canada  Inc.  ("ID Systems") against Checkpoint Systems, Inc.
("Checkpoint"),  held  against  ID  Systems  on  the  plaintiff's  claim  for
Monopolization  of  Commerce,  but  in  favor  of  the  ID  Systems on claims of
Attempted  Monopolization  and  Conspiracy to Monopolize.  In addition, the jury
held  in  favor  of  the  ID  Systems  on  two  tort  claims related to tortious
interference  and  unfair  competition.  Judgment  was entered on the verdict in
favor  of  the  plaintiff,  after  trebling, in the amount of $79.2 million plus
attorneys'  fees  and  costs  to  be  determined  by  the  Court.

On  March  28,  2003, the Court issued an order that vacated the jury verdict on
the  antitrust  claims  and  reduced  the  damages  award  related  to  tortious
interference  and unfair competition from $19 million to $13 million. Checkpoint
subsequently  filed  an  additional  motion to further reduce the $13 million by
$2.1 million based on a prior agreement between the parties and a previous Order
by  the  Court.  The  Court  granted  the  Checkpoint's  motion,  and on May 20,
2003  further  reduced  the  judgment from $13 million to $10.9 million.  On the
same date, the Court stayed execution of the judgment upon the posting of a bond
in  the  amount  of  $11.3  million  by  Checkpoint.

Both  ID  Systems  and  Checkpoint  filed  appeals to the Third Circuit Court of
Appeals related to the various decisions of the Court.  Oral arguments for these
appeals  were  heard  on  March  30,  2004.

On August 1, 2004, ID Systems and Checkpoint entered into a settlement agreement
effective  July  30,  2004,  pursuant  to  which Checkpoint agreed to pay $19.95
million,  in  full  and  final  settlement  of claims covered by the litigation.
Payment  in  full  was  received  on  August  5,  2004.  As provided when Sentry
purchased  ID  Systems,  the  proceeds  of the settlement will be distributed to
former  shareholders  of  ID  Systems,  after  payment  of  litigation  fees and
expenses.  The  agreement  includes  mutual  releases  between  the  parties for
complaints  arising  from  activities prior to the date of the agreement, except
for  any  contractual obligations and any future claims for patent, copyright or
trademark  infringement.  The  agreement  is  not  an  acknowledgement  of  any
wrongdoing  or  liability  by  either party. A Stipulation of Dismissal has been
filed  with  the  Third  Circuit  Court of Appeals to finally conclude the legal
proceedings.

10.     GENERAL

10.01    The  provisions  of  the  Addendum, if any, shall be incorporated into
         this  Agreement  and  form  part  hereof.

10.02    This  Agreement  shall  be  binding  upon  the  undersigned  and  the
         respective  executors,  administrators,  successors and assigns of the
         undersigned, but the undersigned shall not assign any of the rights or
         obligations  of  the  undersigned  hereunder without the prior written
         consent  of  the  Bank.

10.03    The  failure  of  either  the  undersigned  or  the  Bank  to  require
         performance  by  the  other  of  any  provision hereof shall in no way
         affect  the  right thereafter to enforce such provision; nor shall the
         waiver  by  either  party  of any breach of any covenant, condition or
         proviso  of this Agreement or any other agreement between the Bank and
         the  undersigned be taken or held to be a waiver of any further breach
         of  the  same  covenant,  condition  or  proviso.

10.04     This Agreement shall be in addition to and not in substitution for any
          other  agreement  between  the  undersigned  and  the  Bank.

10.05     The  undersigned will execute, and agrees to be bound by the terms and
          conditions  contained  in,  the  Bank's  standard form of Operation of
          Account  Agreement  or  appropriate form of current account authority.
          Without  limiting  the  generality  of  the foregoing, the undersigned
          agrees  that  any statement of the Account provided to the undersigned
          shall  be deemed to be a correct and accurate statement of the Loan as
          at  the date of the statement, unless the undersigned has notified the
          Bank  of  errors,  irregularities  or  omissions within the thirty day
          period  specified  in  the  Operation  of Account Agreement or current
          account  authority.



10.06     All  payments relating to the Loan made by the undersigned pursuant to
          this  Agreement  shall  be  paid  in the currency in which the Loan is
          outstanding.  All  other  amounts  owing  hereunder  shall  be paid in
          Canadian  dollars  except  as  otherwise  herein  agreed.

     In  the event the Bank is required to recover any amount owing hereunder by
way  of  judicial  proceeding,  all  amounts owing hereunder shall be payable in
Canadian  dollars.  Notwithstanding  the  foregoing,  the  obligation  of  the
undersigned  under  this Agreement to make payments in U.S. dollars shall not be
discharged  or  satisfied  by  any  tender  or recovery pursuant to any judgment
expressed  in  or converted into Canadian dollars except to the extent that such
tender or recovery shall result in the effective receipt by the Bank of the full
amount of U.S. dollars so payable hereunder.  Accordingly, the obligation of the
undersigned shall be enforceable as an alternative or additional cause of action
for  the purpose of recovery in Canadian dollars of the amount (if any) by which
such  effective  receipt  shall fall short of the full amount of U.S. dollars so
payable  hereunder  and shall not be affected by any judgment being obtained for
any  other  sums  due  hereunder.

     For  purposes of recovery by the Bank of amounts debited to the U.S. Dollar
Account,  the  Canadian  Dollar Equivalent Amount shall apply.  "Canadian Dollar
                                                                 ---------------
Equivalent  Amount" shall mean, on any date, the amount of Canadian dollars into
- ------------------
which  U.S.  dollars  may be converted at the Bank's applicable noon spot buying
rate  on  the  date  such  conversion  is  made.

10.07     Time  shall  be  of  the  essence  of  this  Agreement.

10.08     If  more  than one person signs this Agreement, the obligations of the
