Exhibit 2.1


                            STOCK PURCHASE AGREEMENT



         AGREEMENT made the 13th day of August 2002 by and among DIVERSIFIED
SECURITY SOLUTIONS, INC. ("DVS"), having an address at 280 Midland Avenue,
Saddle Brook, New Jersey 07663, PHOTO SCAN SYSTEMS, Inc. ("Buyer"), a California
corporation having an office at 3281 San Fernando Road, Los Angeles, CA 90065,
NATIONAL SAFE OF CALIFORNIA, INC. ("Company"), a California corporation having
an address at 2334 West Valencia Avenue, Fullerton, California 92833 and LEE A.
KANN ("Seller") an individual having an address at 1406 Janeen Way, Anaheim,
California 92801.

                              W I T N E S S E T H:

         WHEREAS, Seller is the owner of Five Thousand (5,000) shares (the
"Shares") of the capital stock, without par value, of the Company, which Shares
constitute all of the presently issued and outstanding securities of the Company
of every class;

         WHEREAS, Seller, has agreed to sell, and Buyer has agreed to purchase,
all of the Shares upon the terms, subject to the conditions and in reliance on
the representations and warranties hereinafter set forth;

         NOW, THEREFORE, in consideration of the respective agreements
hereinafter set forth, the parties agree as follows:

         ARTICLE I. Sale of Shares, Consideration, Payment and Related Matters.
On the basis of the representations and warranties contained in and subject to
the terms and conditions of this Agreement:

         1.01 Sale. Seller shall at the Closing (as hereinafter defined) sell,
assign, transfer, convey and deliver to Buyer, and Buyer shall purchase, the
Shares, free and clear of all liens, claims, charges, equities, encumbrances,
restrictions and voting agreements of every kind, for the consideration, and
payable as, hereinafter provided.












Certificates for the Shares shall be delivered by Seller to Buyer at the Closing
duly endorsed, or accompanied by stock powers duly endorsed, in blank. The
certificates for the Shares and stock powers, if any, shall be delivered at the
Closing to the Company which shall promptly issue new certificates for the
Shares, in the same amounts, in the name of Buyer.

         1.02 Purchase Price and Payment.

         1.02(a) Subject to the provisions and adjustments hereinafter set forth
in this Article, the aggregate purchase price for the Shares shall be $2,000,000
(the "Purchase Price"). The Purchase Price assumes that at the Closing, Company
shall have cash and/or account receivables of $400,000 ("Liquid Assets"). If the
Closing Financial Statements (as defined below) show that as of the Closing, the
Company's Liquid Assets are less than $400,000, the Purchase Price will be
reduced pro rata by the amount of the deficit. In the event that as of the
Closing, the Closing Financial Statements show that the Liquid Assets are
greater than $400,000, the Purchase Price will be increased by a total of 80% of
the surplus over and above $400,000. The number of adjustment Shares issued
hereunder shall be determined using the Closing Stock Price (as defined below).

         The Purchase Price subject to the terms and conditions of this
Agreement and to the adjustment provided for in this Section shall be paid at
the Closing in fully paid, and nonassessable shares of the Common Stock of DVS
(the "Common Stock"), the parent company of Buyer. The number of shares of
Common Stock that Seller shall receive shall be 283,566 which was determined by
dividing the Purchase Price by the average closing sale price of DVS's Common
Stock on the American Stock Exchange for the 10 trading days ending 5 trading
days immediately prior to the Closing (the "Closing Stock Price"). DVS will
issue to Seller one stock certificate for 212,675 shares (the "Escrow Property")
representing $1,500,000 of the Purchase Price, which shall be held in Escrow
along with a stock power that is medallion guaranteed as provided herein and one
stock certificate for 70,891 shares representing $500,000 of the Purchase Price.

         1.02(b) At the Closing, Buyer shall loan Seller $500,000, which loan
shall be subject to the terms and conditions of the promissory note payable to
Buyer attached hereto as Exhibit 1.02(b).




                                       2







         1.02(c) In the event that one year from the date of the Closing (the
"Reference Date"), the then Current Market Price (as that term is hereinafter
defined) of one share of Buyer's Common Stock is less than $7.053, DVS and/or
Buyer shall at their sole discretion, within 10 days after the Reference Date,
either purchase the Escrow Property for $1,500,000 provided however, if the
Purchase Price is adjusted pursuant to Section 1.02(a) then the amount of this
payment will be adjusted on a pro rata basis according to the adjustment in the
Purchase Price (the "Purchase Option") or pay Seller an amount equal to the
difference between (i) $1,500,000 and (ii) 212,675 (provided however, if the
Purchase Price is adjusted pursuant to Section 1.02(a) then this number will
also be adjusted on a pro rata basis according to the adjustment in the Purchase
Price) multiplied by the average closing sale price of the Common Stock on the
American Stock Exchange for the 10 trading days immediately prior to the
Reference Date (the "Current Market Price"), such payment hereinafter referred
to herein as the ("Difference Payment"). If the Common Stock is no longer traded
on the American Stock Exchange, the Current Market Price for the Common Stock
shall be the last sale price of the Common Stock on Nasdaq or any other
automated quotation system or, if the Common Stock shall not be included in any
automated quotation system, the closing ask quotation for the Common Stock as
reported by the National Quotation Bureau Incorporated. If the Common Stock is
not trading on any of the above mentioned markets, the Current Market Price
shall be the fair market value of Common Stock on the Reference Date as
determined by a member firm of the New York Stock Exchange, Inc. selected by the
Board of Directors, provided such firm shall be reasonably acceptable to Seller.

         1.02(d) Promptly following the Closing, the accounting firm of Mary
Cottrell, CPA, or such other recognized firm as Buyer may designate (the
"Auditor"), shall audit the balance sheet of the Company as of June 30, 2002 and
shall prepare (i) an unaudited balance sheet for the interim period ending on
the day proceeding the Closing (the audited and unaudited balance sheets are
referred to herein as the "Closing Balance Sheet"), (ii) the related audited
statements of operations, changes in equity and cash flows for the two years
than ended and (iii) an unaudited interim statement of operations for the
interim period beginning on July 1, 2002 and ending on the day preceding the
Closing (the audited and unaudited statement of operations are referred to
herein as the "Closing Statement of Operations, Changes in Equity and Cash
Flows") (the Closing Balance Sheet and Closing Statement of Operations, changes
in Equity and Cash Flows




                                       3







being hereinafter collectively referred to as the "Closing Financial
Statements"). The Closing Financial Statements shall be prepared in accordance
with accounting principles generally accepted in the United States of America
(US GAAP), except that the unaudited financial statements may omit footnote
disclosure. The Closing Financial Statements shall include a balance sheet as of
December 31, 2001 and statements of operations, changes in equity and cash flows
for the two years then ended. Seller hereby agrees to cooperate fully with such
Auditor and provide such Auditor with any reasonable assistance such Auditor may
request from Seller in connection with the performance of such audit.
Notwithstanding the foregoing, buyer acknowledges that the audit is its sole
responsibility. Seller will pay up to a total of $5,000 of the fees and expenses
incurred in conducting the audit and preparing the financial statements
contemplated herein. Copies of the proposed Closing Financial Statements shall
be delivered to Buyer and Seller not later than 45 days after the Closing and
shall be deemed accepted by them as the final Closing Financial Statements
unless written objection thereto, specifying any matters in dispute, is given by
either Buyer or Seller to the other within 10 days following receipt thereof.
Should written objection be made by either Buyer or Seller as aforesaid, the
parties shall attempt in good faith to resolve any matters in dispute following
which they shall prepare final Closing Financial Statements reflecting any
adjustments or changes agreed to by them in the proposed Closing Financial
Statements; provided, however, if the Seller and the Buyer are unable to agree
on the Closing Financial Statements, the dispute shall be submitted to binding
arbitration before the American Arbitration Association in Orange County,
California under its rules for Commercial Arbitrations. The Buyer and Seller
will each pay one-half of the fees and costs of the American Arbitration
Association, and shall each pay their own costs and attorney's fees incurred
therein.

         1.02 (e) The Escrow Property shall be established by a separate
agreement (the "Escrow Agreement"). The form of the Escrow Agreement is attached
hereto as Exhibit 1.02 (d). Milberg Weiss Bershad Hynes & Lerach LLP shall act
as the escrow agent (the "Escrow Agent") and the Escrow Property shall be held
pursuant and subject to this Agreement and the Escrow Agreement. After the
parties have agreed on the Closing Financial Statements, if such statements
show that the Liquid Assets are less than $400,000, Buyer will promptly make the
adjustment required by Section 1.02(a) and DVS will send to the Escrow Agent a
stock certificate representing the adjusted Purchase Price and Escrow Agent will
send such certificate that it was holding in escrow to DVS or its transfer
agent. If the Closing




                                       4







Financial Statements show that the Liquid Assets are greater than $400,000,
Buyer will promptly make the adjustments required by Section 1.02 (a) and DVS
will promptly send Escrow Agent a certificate for such additional shares
required by such adjustment (the "Additional Certificate") and such Additional
Certificate will become part of the Escrow Property. If one year from the date
of the Closing, the Common Stock is equal to or greater than $7.053 per share,
then Escrow Agent shall promptly send the Escrow Property to Seller; provided,
however, if the Common Stock is less than $7.053 per share, then, within the
time permitted by Section 1.02(c) Buyer shall provide Seller and Escrow Agent
with written notice of whether it has elected the Purchase Option or the
Difference Payment. If the Buyer shall have chosen the Purchase Option, it shall
send Escrow Agent a check (or other certified funds) made payable to Seller in
the amount of Purchase Option, wherein Escrow Agent will promptly after receipt
of such check send it to Seller and send the Escrow Property to Buyer provided
however, if Buyer and Seller agree in writing Buyer may make a wire transfer to
Seller in lieu of the aforementioned check. If the Buyer shall have chosen the
Difference Payment, Escrow Agent will promptly send the Escrow Property to
Seller.

         1.03 Undisclosed Liabilities. If during the ninety (90) day period
commencing with the date of the Closing, Buyer determines that the Company is
liable or potentially liable for a Material Undisclosed Liability (as defined
herein), Buyer shall promptly give written notice thereof to Seller. Such notice
shall specify the name, address, basis and amount of the Material Undisclosed
Liability and shall be accompanied by any written support then available to
Buyer. Within five (5) days of receipt of said notice, Seller shall either (i)
notify Buyer that Seller does not dispute the claim, in which case the amount
necessary to satisfy the Material Undisclosed Liability shall be paid to the
Buyer; or (ii) notify Buyer that the claimed Material Undisclosed Liability is
disputed, in which case Seller and Buyer shall thereafter attempt in good faith
to negotiate with the party claiming such liability a resolution of the asserted
Material Undisclosed Liability on terms reasonably satisfactory to the Seller
and Buyer. As used herein, the term Material Undisclosed Liability shall mean a
debt, obligation, contract, tort, claim or other liability claimed by any
person, firm or entity against Company, other than claims the Company's usual
and customary operating expenses incurred in the ordinary course of business.

afford to Buyer, its attorneys, accountants and other representatives, upon
reasonable request, full and free access during normal business hours to all
properties, books, records and other documents of the Company, including the
right to make extracts there from or copies thereof, and shall furnish Buyer

Seller, return to the Company all written information so furnished and all
copies thereof and extracts therefrom.

         5.01(b) The Company shall, and the Seller shall cause the Company to,
refrain from taking or omitting to take any action or entering into any
transaction which, had such action been taken or omitted or such transaction
entered into immediately prior to execution of this Agreement, would have caused
any of the representations, warranties or agreements of Seller or the Company in
this Agreement to be untrue, incorrect or inaccurate in any material respect as
of the time of execution of this Agreement or would cause any such
representations, warranties or agreements to be




                                       6







untrue, incorrect or inaccurate in any material respect as of the time
immediately following such action, omission or transaction or as of the date of

set forth or provided in the Seller's Schedule, the Company shall and Seller
shall cause the Company to (i) conduct its business only in the usual, regular
and ordinary course in the same manner as heretofore, (ii) use its best efforts
to preserve its business, properties and assets, maintain its business
organization intact, keep available the services of its present officers and
employees and preserve its goodwill and existing relationships with customers,
suppliers and others having dealings with it, (iii) maintain its properties in
customary repair, order and condition, reasonable use and wear and tear
accepted, (iv) maintain insurance on its properties and with respect to the
conduct of its business in amounts not less than and of such kinds as are
comparable to the insurance in effect on the date of this Agreement, and (v)
maintain its books, accounts and records in the usual, regular and ordinary
manner.

         5.02 Adverse Circumstances.

         5.02(a) Seller and the Company shall promptly notify Buyer, as soon as
any of them obtains knowledge, of any facts, circumstances or occurrences which
have adversely affected or might reasonably be expected to adversely affect the
business, properties, assets, financial condition or prospects of the Company or
which could or reasonably might be expected to cause any of their
representations, warranties or agreements in this Agreement to be untrue,
incorrect or inaccurate in any material respect.

         5.02(b) Should Buyer elect to consummate the Closing after receipt of
any notice pursuant to subsection 5.02(a), then, anything elsewhere in this
Agreement to the contrary notwithstanding, Buyer shall be deemed to have waived
any rights or claims which it might possess under this Agreement, or otherwise,
against Seller or the Company with respect to the matters expressly referred to
(but only if and to the extent such matters are adequately and properly referred
to or disclosed) in such notice.

Commercial Code) and (iii) such counsel, without however having made any
independent investigation thereof, has no reason to believe that any of the
other representations and warranties of Seller in this Agreement or in the

their power) and to use its commercially reasonable efforts to obtain compliance

         ARTICLE VII. Additional Agreements of the Parties.

         7.01 Covenant Not to Compete.

         7.01(a) In order to induce Buyer to enter into and consummate the
transactions provided for in this Agreement, Seller covenants and agrees that
(i) during the period of five (5) years following the date of Closing he will
not, without the prior written consent of Buyer in each instance, directly or
indirectly, whether for himself or for any other person and whether as
proprietor, principal, stockholder, partner, agent, director, officer, employee,
consultant, independent contractor or in any other capacity, engage in, or have
any interest in any business or other entity that provides technology-based
security solutions for commercial uses or which engages in, the manufacture,
sale or distribution of commercial security related products anywhere in, or
which has an office or place of business anywhere in, the continental United
States or (ii) at any time after the Closing knowingly do any act which would
impair the value of the business, operations or assets of, or injure the
goodwill or reputation of, Buyer or the Company or divert any of its business or
employees. Without limiting the generability of the foregoing, Seller agrees
that during such five year period he will not solicit any business from any
person, firm, corporation or entity which was a customer of the Company within
the three year period prior to the Closing nor will he hire any person who was
an employee of the Company at the date of Closing.

         7.01(b) Seller agrees that each provision of subsection 7.01(a) is
reasonable and necessary for the protection of Buyer; that each such provision,
and the period or periods of time, geographical areas and types and scopes of
restrictions on his activities specified therein, are and are intended to be
divisible; that if any portion thereof (including any sentence, clause or part)
shall be held contrary to law or invalid or unenforceable in any respect in any
jurisdiction, or as to any one or more periods of time, areas or business
activities, or any part thereof, the remaining provisions shall not be affected
but shall remain in full force and effect as to the other and remaining parts;
and that any such invalid or unenforceable provision shall be deemed, without
further action on the part of the parties hereto, modified, amended and limited
to the extent necessary to render the same valid and enforceable in such
jurisdiction. Seller further




                                       10






recognizes and agrees that any violation of his agreement in subsection 7.01(a)
would cause such damages to Buyer as would be irreparable and the exact amount
of which would be impossible to ascertain and that, for such reason, among
others, Buyer shall be entitled, as a matter of course, to injunctive relief
from any court of competent jurisdiction restraining any further violation. Such
right to injunctive relief shall be cumulative and in addition to and not in
limitation of all other rights and remedies which Buyer may possess.

         7.02 Further Assurances. From and after the date of this Agreement and
the date of Closing, the parties hereto shall from time to time, at the request
of any other party and without further consideration, do, execute and deliver,
or cause to be done, executed and delivered, all such further acts, things and
instruments as may be reasonably requested or required more effectively to
evidence and give effect to the transactions provided for in this Agreement
without limiting the generability of the foregoing, the parties shall cooperate
with each other (i) in connection with the filing of the Company's tax returns
with respect to any period up to the Closing, (ii) the conducting of the audit
contemplated by Section 1.02(d), and (ii) in the furnishing of information,
evidence, testimony and other assistance in connection with any legal actions,
proceedings or disputes involving any of the parties based upon any contracts,
agreements, arrangements or other matters whether occurring prior or subsequent
to the date of this Agreement and the date of Closing.

         7.03 Consulting Agreement. On the closing, Seller and Buyer shall
execute and enter a consulting agreement substantially in the form of Exhibit
7.03 attached hereto.

         7.04 Press Release. Seller hereby agrees that after the execution of
this Agreement by all parties, DVS may at its discretion issue a press release
announcing the acquisition of the Company.

         7.05 Lease. On the Closing, Buyer shall execute and enter into a lease,
substantially in the form of Exhibit 7.05 attached hereto for a term of six (6)
months commencing as of the date of Closing for the premises located at 2334
West Valencia Avenue, Fullerton, California 92833.

         7.06 Licenses. Buyer acknowledges that Seller is the qualified and/or
designated manager for the Company's alarm and locksmith's licenses. Within 60
days of the Closing, Buyer will take such steps as are necessary to substitute
another person as the designated person for such licenses. Buyer will provide
Seller's attorney with




                                       11






appropriate documentation showing such substitution was made. Buyer, further
acknowledges that Ronald Aube and John Weaver are currently the Responsible
Managing Employees on the C7, C61, D16 and HIC licenses issued to the Company by
the State of California Contractor's License Board.

         ARTICLE VIII. Survival, Indemnification and Related Matters.

         8.01 Survival. All of the provisions of, and all of the
representations, warranties, covenants and agreements of the parties in, or in
any document or other instrument executed or delivered pursuant to or in
connection with, this Agreement shall, unless waived, survive and continue in
force and effect from and after the date of Closing and any investigation at any
time made by or on behalf of any party.

         8.02 Indemnification. Buyer and Seller:

         8.02(a) Shall each indemnify and hold the other free and harmless from
and against and shall reimburse the other for any and all claims, liabilities,
damages, losses, judgments, costs and expenses including reasonable counsel fees
and other reasonable out-of-pocket expenses (the foregoing being hereinafter
collectively referred to as "damages") arising out of or resulting from any
inaccuracy or inadequacy in or breach or default of any of its or his
representations, warranties, covenants or agreements in, or in any document or
other instrument executed or delivered pursuant to or in connection with, this
Agreement.

         8.02(b) Shall give the other written notice of any claim, demand,
action, suit or proceeding raised, brought, threatened, made or commenced
against it or the Company relating to any matter to which the indemnification
provisions of this Section 8.02 apply, and such other party shall have the
right, at its expense, to participate in the settlement and defense thereof
using counsel of its own choice. Failure to give such notice shall not, however,
affect the liability of any other party under this Agreement unless such failure
shall materially adversely prejudice the defense thereof by such other party.
Nothing herein shall limit the right of any party to settle any claim, demand,
action, suit or proceeding brought or threatened against it, provided, however,
that in any such event no other party shall be bound by the amount or terms of
any such settlement not consented to by it.

         8.02(c) The provisions of this Section 8.02 shall not be construed as a
waiver by any party of any other rights or remedies which it may possess,
whether under this Agreement, at law or in equity, arising out of or resulting
from




                                       12







any breach or default of or inaccuracy or inadequacy in any other party's
representations, warranties, covenants or agreements.

         ARTICLE IX. Miscellaneous.

         9.01 Broker. Seller shall pay any commission, including but not limited
