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  our
            supervision,  to ensure that  material  information  relating to the
            small business issuer, including its consolidated  subsidiaries,  is
            made  known to us 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 our
            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  (and  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.
