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