Web Snapshots
For monitoring purposes, the TANDBERG system’s web interface shows a snapshot of the
incoming video if the system is in a call. Outside of a call, the web snapshot will reflect the local
main camera view or another selectable video source on the system. The snapshot image is
updated every five seconds.
In a call, the system’s web interface also shows and allows selecting the DuoVideo source.
The snapshot picture information is protected by the following security mechanisms:
•
The web snapshots are not stored on the TANDBERG system.
•
The web snapshots are protected by the TANDBERG system’s IP password.
•
The web snapshots are not visible for encrypted calls.
•
The web snapshot functionality is disabled by default. It may be turned on only via the local
codec interfaces (on-screen menu or RS-232 dataport connection).
