The contents of the context menu items and the active cell buttons depend on the camera and application settings.

Stream selection: Allows to choose the stream to display in the camera cell.

The following streams are available:

Note

Both main and additional streams are available for selection only in case if they are encoded to H.264 video codec in the source and the browser are capable to decode and display it.

Configuration of video streams should be performed by the surveillance system administrator.

Auxiliary stream will always be available for selection. The server generates this stream in MJPEG from the original stream regardless of what video codec this original stream was encoded.

When assigning a camera to the cell for the first time, the auxiliary stream will be displayed by default.

Stream selection settings will be saved for each camera in the cell.

Warning

When viewing many cameras in H.264 video codec simultaneously, problems with the playback may occur. In such cases it is recommended to decrease the load to the browser by activating the Switch to MJPEG in case of video playback issues option in the Settings window.
