ITEM 4.  DESCRIPTION OF SECURITIES

         (Not applicable)


ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

          William A. Perlmuth, a director of the Registrant, is of counsel to
Stroock & Stroock & Lavan LLP, counsel for the Registrant. Mr. Perlmuth holds
(i) 750,729 shares of Common Stock as Executor of the Estate of Arthur J.
Minasy, (ii) 130,010 shares of Common Stock as trustee under trusts for the
benefit of Mr. Minasy's adult children, and (iii) 3,327 shares of Common Stock
which he owns beneficially. Other members of such firm beneficially own
additional shares of Common Stock of the Registrant. Mr. Perlmuth is also the
holder of options to purchase 33,299 shares of Common Stock of the Registrant
(of which options to acquire 18,299 shares are currently exercisable or will
become exercisable within the next 60 days). Under the policies of Stroock &
Stroock & Lavan LLP, Mr. Perlmuth will share any economic benefits with other
members of the firm.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

          Section 145 of the General Corporation Law of the State of Delaware
(the "DGCL") provides, in summary, that directors and officers of Delaware
corporations are entitled, under certain circumstances, to be indemnified
against all expenses and liabilities (including attorneys' fees) incurred by
them as a result of suits brought against them in their capacity as a director
or officer, if they acted in good faith and in a manner they reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
their conduct was unlawful; provided, that no indemnification may be made
against expenses in respect of any claim, issue or matter as to which they shall
have been adjudged to be liable to the corporation, unless and only to the
extent that the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, they are fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper. Any such
indemnification may be made by the corporation only as authorized in each
specific case upon a determination by the stockholders or disinterested
directors that indemnification is proper because the indemnitee has met the
applicable standard of conduct. Article Tenth of the Registrant's Amended and
Restated Certificate of Incorporation entitles officers, directors and
controlling persons of the Registrant to indemnification to the full extent
permitted by Section 145 of the DGCL, as the same may be supplemented or amended
from time to time.

          Article Ninth of the Registrant's Amended and Restated Certificate of
Incorporation provides that no director or officer shall have any personal
liability to the Registrant or its stockholders for any damages for breach of
fiduciary duty as a director, except that such provision does not limit or
eliminate the liability of any director or officer (i) for breach of such
director's or officer's duty of loyalty to the Registrant or its shareholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, or (iii) for any transaction from
which such director or officer derived an improper personal benefit.

          The Registrant maintains directors' and officers' liability insurance
which covers the directors and officers of the Registrant against certain
liabilities and expenses incurred by them in their capacities as such, and
insuring the Registrant under certain circumstances, in the event that
indemnification payments are made by the Registrant to such officers and
directors.

          4.1       Amended and Restated Certificate of Incorporation of Sentry
                    Technology Corporation (incorporated by reference to Exhibit
                    3.1 to Registration Statement on Form S-4 (No. 333- 20135)).

          4.2       Amended and Restated By-Laws of Sentry Technology
                    Corporation (incorporated by reference to Exhibit 3.2 to
                    Registration Statement on Form S-4 (No. 333-20135)).

          4.3       Sentry Technology Corporation Retirement Savings 401(k) Plan

                    Statement on Form S-4 (No. 333-20135)).

          24        Power of Attorney (included at page II-5).*

          In connection with the merger of Knogo North America Inc. and Video
Sentry Corporation into subsidiaries of the Registrant on February 12, 1997, the
Knogo North American Inc. Retirement Savings 401(k) Plan (the "Prior Plan") was
adopted by the Registrant and renamed the Sentry Technology Corporation
Retirement Savings 401(k) Plan (the "Amended Plan"). The Prior Plan was
submitted by the Registrant to the Internal Revenue Service (the "IRS") in a
timely manner and Knogo North America Inc. made all changes required by the IRS
in order to qualify the Prior Plan. The Registrant undertakes to submit any
amendments to the Amended Plan to the IRS in a timely manner and will make all
changes required by the IRS in order to qualify the Amended Plan and any
amendments thereto.

*        Filed herewith.

ITEM 9.  UNDERTAKINGS

          (a) The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement;

          (2) That, for the purpose of determining any liability under the 1933
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

          (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or 15(d) of the 1934 Act and the annual
report for the Plan pursuant to Section 15(d) of the 1934 Act that are
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (c) Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 1933 Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

                            SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Hauppauge, State of New York, on the 31st day of
July, 1997.

ITEM 4.  DESCRIPTION OF SECURITIES

         (Not applicable)

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

          William A. Perlmuth, a director of the Registrant, is of counsel to
Stroock & Stroock & Lavan LLP, counsel for the Registrant. Mr. Perlmuth holds
(i) 750,729 shares of Common Stock as Executor of the Estate of Arthur J.
Minasy, (ii) 130,010 shares of Common Stock as trustee under trusts for the
benefit of Mr. Minasy's adult children, and (iii) 3,327 shares of Common Stock
which he owns beneficially. Other members of such firm beneficially own
additional shares of Common Stock of the Registrant. Mr. Perlmuth is also the
holder of options to purchase 33,299 shares of Common Stock of the Registrant
(of which options to acquire 18,299 shares are currently exercisable or will
become exercisable within the next 60 days). Under the policies of Stroock &
Stroock & Lavan LLP, Mr. Perlmuth will share any economic benefits with other
members of the firm.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

          Section 145 of the General Corporation Law of the State of Delaware
(the "DGCL") provides, in summary, that directors and officers of Delaware
corporations are entitled, under certain circumstances, to be indemnified
against all expenses and liabilities (including attorneys' fees) incurred by
them as a result of suits brought against them in their capacity as a director
or officer, if they acted in good faith and in a manner they reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
their conduct was unlawful; provided, that no indemnification may be made
against expenses in respect of any claim, issue or matter as to which they shall
have been adjudged to be liable to the corporation, unless and only to the
extent that the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, they are fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper. Any such
indemnification may be made by the corporation only as authorized in each
specific case upon a determination by the stockholders or disinterested
directors that indemnification is proper because the indemnitee has met the
applicable standard of conduct. Article Tenth of the Registrant's Amended and
Restated Certificate of Incorporation entitles officers, directors and
controlling persons of the Registrant to indemnification to the full extent
permitted by Section 145 of the DGCL, as the same may be supplemented or amended
from time to time.

          Article Ninth of the Registrant's Amended and Restated Certificate of
Incorporation provides that no director or officer shall have any personal
liability to the Registrant or its stockholders for any damages for breach of
fiduciary duty as a director, except that such provision does not limit or
eliminate the liability of any director or officer (i) for breach of such
director's or officer's duty of loyalty to the Registrant or its shareholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, or (iii) for any transaction from
which such director or officer derived an improper personal benefit.

          The Registrant maintains directors' and officers' liability insurance
which covers the directors and officers of the Registrant against certain
liabilities and expenses incurred by them in their capacities as such, and
insuring the Registrant under certain circumstances, in the event that
indemnification payments are made by the Registrant to such officers and
directors.

          4.2       Amended and Restated By-Laws of Sentry Technology

          24        Power of Attorney (included at page II-5).*

          In connection with the merger of Knogo North America Inc. and Video
Sentry Corporation into subsidiaries of the Registrant on February 12, 1997, the
Knogo North American Inc. Retirement Savings 401(k) Plan (the "Prior Plan") was
adopted by the Registrant and renamed the Sentry Technology Corporation
Retirement Savings 401(k) Plan (the "Amended Plan"). The Prior Plan was
submitted by the Registrant to the Internal Revenue Service (the "IRS") in a
timely manner and Knogo North America Inc. made all changes required by the IRS
in order to qualify the Prior Plan. The Registrant undertakes to submit any
amendments to the Amended Plan to the IRS in a timely manner and will make all
changes required by the IRS in order to qualify the Amended Plan and any
amendments thereto.

*        Filed herewith.

ITEM 9.  UNDERTAKINGS

          (a) The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement;

          (2) That, for the purpose of determining any liability under the 1933
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

          (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or 15(d) of the 1934 Act and the annual
report for the Plan pursuant to Section 15(d) of the 1934 Act that are
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (c) Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 1933 Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

                            SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Hauppauge, State of New York, on the 31st day of
July, 1997.
