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.
