NCast Telepresenter Reference Manual
The HTTP API password allows access to archived files. This password permits HTTP access to the archive
list, allows downloading of the archive and details file and the removal of one or more archived files. All of
these operations utilize special HTTP URLs described in Section 9.3. Commonly available programs such as
“wget” may be executed from shell scripts to automate this archive download function. There is no login page
for a backup operator using the web interface.

The Web Control page allows configuration of security settings related to use and access of the web
administrative interface.
3.3.1. HTTP/HTTPS Access
Normal web access, which is unprotected and insecure, is accomplished through use of the HTTP protocol
typically utilizing port 80. Secure access using HTTPS (the SSL protocol) utilizes port 443. Administration of
the Telepresenter in open and insecure networks without the use of HTTPS presents a security risk and
should be avoided.
The Web Control page allows three different options related to Viewer and Administrative access.
• All HTTP – Utilizes HTTP for Viewer and Administrative access.
• Viewer HTTP/Admin HTTPS – Utilizes HTTPS for Administrative access
• All HTTPS – Viewers and Administrators must use HTTPS
The downside of using HTTPS is that SSL Certificates (which usually require an annual fee or license
payment) are required for each Telepresenter unit. Non-authoritative certificates may be used, but Viewers
will see ominous warning notices in their browsers about the certificate, asking the user to accept the validity
of the connection. Also, client players such as Quicktime, which need to download .sdp files using HTTPS
protocol, may not function correctly if the certificate is not valid. Consult with your network administrator
about certificate availability for your organization.
Access using HTTPS is straightforward. Simply use the “https” prefix:
