EXHIBIT 10(F)

                       CONFIDENTIALITY, NONCOMPETITION AND
                            NONSOLICITATION AGREEMENT

         Confidentiality, Noncompetition and Nonsolicitation Agreement (the
"Agreement") effective as of April 27, 1998 among Guardian International, Inc.,
a Nevada corporation (the "Company"), and Jeff Chivers ("Chivers").

                                    RECITALS

         A. The Company, Richard Clark ("Clark"), David Weston ("Weston"),
Chivers and Alan Dubow ("Dubow" and together with Clark, Weston and Chivers, the
"Sellers") entered into a Stock Purchase Agreement (the "Stock Agreement")
effective as of April 17, 1998 pursuant to which the Company agreed to purchase
all of the outstanding common stock, $.15 par value per share (the "Common
Stock") of Precision Security Systems, Inc., a Florida corporation, from
Sellers.

         B. Chivers acknowledges that he will obtain confidential and
proprietary information relating to the business of the Company as a result of
consummation of the transactions contemplated by the Stock Agreement, and
acknowledges that the covenants not to compete and confidentiality provisions in
this Agreement are reasonable.

                                    AGREEMENT

         l.       CONFIDENTIALITY.

                  a. Chivers agrees that he will hold in a fiduciary capacity
for the benefit of the Company, and shall not, directly or indirectly, use or
disclose, except as authorized by the Company, any Confidential Information (as
defined below) that Chivers may have or acquire (whether or not developed or
compiled by Chivers and whether or not Chivers has been authorized to have
access to such Confidential Information). The term "Confidential Information" as
used in this Agreement shall mean and include any material information, data and
know-how relating to the business of the Company that is disclosed to Chivers by
the Company or known by him as a result of his relationship with the Company (or
a company acquired by the Company) and not generally within the public domain
(whether constituting a trade secret or not) including, without limitation, the
following: financial information, supply and service information, marketing
information, personnel information, customer information and information with
respect to any corporate affairs that the Company treats as confidential.

                  b. The term "Confidential Information" does not include
information that has become generally available to the public by the act of the
Company or by the act of one who has the right to disclose such information
without violating any right of the Company or the customer to which such
information pertains.


<PAGE>

                  c. Nothing in this Section 1 shall prevent Chivers from
disclosing any Confidential Information to the extent such disclosure is
required by law or any order of a court or government authority with
jurisdiction, provided, however, that Chivers agrees to give the Company advance
written notice as soon as possible of the Confidential Information required to
be disclosed, and at the Company's request, to use his best efforts to obtain
assurances that the Confidential Information required to be disclosed will be
maintained on a confidential basis and will not be disclosed to a greater degree
than required by law.

                  d. These rights of the Company are in addition to those rights
the Company has under the common law or applicable statutes for the protection
of trade secrets.

         2. COVENANT NOT TO COMPETE. Chivers agrees that he will not engage or
participate, directly or indirectly, in any business that competes with the
business of the Company in Dade County, Broward and Palm Beach County, Florida,
whether as an employee, employer, consultant, agent, principal, partner,
stockholder, corporate officer, director, or other representative capacity, for
a period of four (4) years after the date of this Agreement. Notwithstanding the
foregoing, Chivers may (i) hold an investment representing less than a 5%
interest in any publicly held entity engaging in a business that competes with
the business of the Company and (ii) be an employee, employer, consultant,
agent, principal, partner, stockholder, corporate officer, director or other
representative of an entity that does not engage in burglar alarm, fire alarm,
closed circuit television and electronic access and control and central
monitoring services; PROVIDED, HOWEVER, that Chivers agrees to refer customers
seeking monitoring services to Company. In the event any court shall refuse to
enforce any portion of the covenant set forth in this Section 2, then such
unenforceable portion shall be deemed eliminated and severed from said contract
for the purposes of said court's proceedings to the extent necessary to permit
the remaining portions of the covenant to be enforced.

         3. NONSOLICITATION. Chivers agrees that he will not, from the date of
this Agreement and forever thereafter, for himself or on behalf of or in
conjunction with any third party solicit any employee of the Company or its
subsidiaries to leave such employment; PROVIDED, that the posting by Chivers or
any entity with which Chivers is involved of general advertisements soliciting
employees shall not constitute the solicitation of any employee of the Company
or its subsidiaries. Chivers further agrees that, from the date of this
Agreement and for an unlimited period thereafter, he will not directly or
indirectly, on his own behalf or in the service of or on behalf of others,
solicit, divert or appropriate, or attempt to solicit, divert or appropriate, to
any competing business, any customers of the Company or its subsidiaries
existing as of the date of this Agreement. If, as of the date of this Agreement,
Chivers is engaged in or associated with the planning or implementing of any
project, program or venture involving the Company and a third party or parties
(a "Venture"), or any discussions, analysis or negotiations with respect to an
investment in, merger, acquisition or purchase, directly or indirectly, of the
stock, assets, or business of any entity (an "Acquisition"), all rights in the
Venture and the Acquisition and any opportunity to make any investment in the
entity to be so acquired (the "Target") shall belong to the Company and shall
constitute a corporate opportunity belonging exclusively to the Company. Except
as approved by the Board of Directors of the Company, Chivers shall not be
entitled to any interest in any such Venture or to invest or solicit any third
party to invest in the Target or

                                       2

<PAGE>

consummate the Acquisition, or to any commission, finder's fee or other
compensation in connection therewith. In the event any court shall refuse to
enforce any portion of the covenants set forth in this Section 3, then such
unenforceable portion shall be deemed eliminated and severed from said contract
for the purposes of said court's proceedings to the extent necessary to permit
the remaining portions of the covenant to be enforced.

         4. REMEDIES. The parties acknowledge that the Company would not have an
adequate remedy at law for money damages if the covenants contained in Sections
1, 2 or 3 were not complied with in accordance with their terms. The parties
therefore agree that in the event of an anticipated breach or actual breach by
Chivers of the provisions of Sections 1, 2 or 3, the Company shall be entitled
to inform in writing all of Chivers' potential or new employers, partners,
shareholders, officers, directors or borrowers of the terms of this Agreement.
Because the breach or threatened breach of any of the covenants in Sections 1, 2
or 3 will result in immediate and irreparable injury to the Company, Chivers
agrees that the Company shall be entitled to an injunction restraining Chivers
from violating Sections 1, 2 and 3 to the fullest extent allowed by law. Chivers
covenants and agrees that if he violates any of the covenants and agreements in
Sections 1, 2 or 3, the Company shall be entitled to an accounting and repayment
of all profits, compensation, commissions, remuneration or benefits which
Chivers directly or indirectly realizes or may realize as a result of or in
connection with a violation. Nothing in this Agreement shall prohibit the
Company from pursuing all other legal or equitable remedies that may be
available to it for a breach or threatened breach, including the recovery of
damages.

         5. ASSURANCES. The parties agree to execute, acknowledge, deliver and
file, or cause to be executed, acknowledged, delivered and filed, all further
instruments, agreements or documents as may be necessary to consummate the
transactions provided for in this Agreement and to do all further acts necessary
to carry out the purpose and intent of this Agreement.

         6. WAIVER. No term or condition of this Agreement shall be deemed to
have been waived, nor shall there be any estoppel against the enforcement of any
provision of this Agreement, except by written instrument of the party charged
with the waiver or estoppel. No written waiver shall be deemed a continuing
waiver unless specifically stated therein, and each waiver shall operate only as
to the specific term or condition waived and shall not constitute a waiver of
the term or condition for the future or as to any act other than that
specifically waived.

         7. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Florida without reference to its
conflicts of law principles.

         8. LITIGATION; PREVAILING PARTY. If litigation is brought concerning
this Agreement, the prevailing party shall be entitled to receive from the
non-prevailing party, and the non-prevailing party shall immediately pay upon
demand, all reasonable attorneys' fees and expenses for the prevailing party.

         9. NOTICES. All notices and other communication required or permitted
under this Agreement shall be in writing and delivered personally or sent by
certified or registered mail,
