Appendix E - CGI Parameters
The Common Gateway Interface (CGI) is a standard for interfacing external applications with
information servers, such as a Web server. A CGI program within the AXIS 2400/2401 allows you
to define special video image features within an embedded URL request and generate simple
HTTP input/output operations for controlling the Pan/Tilt port.
CGI parameter requests are generated in the form of query strings appended to the URL of the
AXIS 2400/2401.
