3. General CGI URL Syntax and Parameters
CGI parameters are written in lower-case and as one word without any underscores or other separators. When the CGI request includes internal camera parameters, these parameters must be written exactly as they are named in the camera or video server. The CGIs are organized in functionally-related directories under the cgi-bin directory. The file extension .cgi is required.
Syntax:
http://<servername>/cgi-bin/<subdir>[/<subdir>...]/<cgi>.<ext> [?<parameter>=<value>[&<parameter>=<value>...]]
Example: Set hostname
http://mywebserver/cgi-bin/admin/setparam.cgi?system_hostname=vivotek
