Exhibit 31.1


                                  CERTIFICATION


I, C. A. Rundell, Jr., certify that:

1.       I have  reviewed  this  quarterly  report on Form 10-QSB of  Integrated
Security Systems, Inc.;

2.       Based  on my  knowledge,  this  report  does  not  contain  any  untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made, not misleading with respect to the period covered by this report;

3.       Based on my knowledge,  the financial  statements,  and other financial
information included in this report, fairly present in all material respects the
financial condition,  results of operations and cash flows of the small business
issuer as of, and for, the periods presented in this report;

4.       I am responsible for establishing and maintaining  disclosure  controls
and  procedures  (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e)) for
the small business issuer and have:

         (a)     Designed such  disclosure  controls and  procedures,  or caused
                 such disclosure controls and procedures to be designed under my
                 supervision,  to ensure that material  information  relating to
                 the  small   business   issuer,   including  its   consolidated
                 subsidiaries,  is  made  known  to me by  others  within  those
                 entities,  particularly  during the period in which this report
                 is being prepared;

         (b)     Evaluated  the  effectiveness  of the small  business  issuer's
                 disclosure controls and procedures and presented in this report
                 my  conclusions  about  the  effectiveness  of  the  disclosure
                 controls and procedures, as of the end of the period covered by
                 this report based on such evaluation; and

         (c)     Disclosed  in this  report  any  change in the  small  business
                 issuer's   internal  control  over  financial   reporting  that
                 occurred during the small business  issuer's most recent fiscal
                 quarter (the small business  issuer's  fourth fiscal quarter in
                 the case of an annual report) that has materially affected,  or
                 is reasonably likely to materially  affect,  the small business
                 issuer's internal control over financial reporting; and

5.       I have  disclosed,  based  on my most  recent  evaluation  of  internal
control over financial  reporting,  to the small business  issuer's auditors and
the audit  committee  of the small  business  issuer's  board of  directors  (or
persons performing the equivalent functions):

         (a)     All  significant  deficiencies  and material  weaknesses in the
                 design  or  operation  of  internal   control  over   financial
                 reporting which are reasonably  likely to adversely  affect the
                 small business issuer's ability to record,  process,  summarize
                 and report financial information; and

         (b)     Any fraud, whether or not material, that involves management or
                 other  employees  who  have a  significant  role  in the  small
                 business issuer's internal control over financial reporting.
