 Default Camera: Using this dropdown, a default camera can be selected for
playback until the camera is changed by a connected data point. Apart from the
configured cameras, the options OFF and Cycle are available to specify either no
playback at all or auto-cycle through all available cameras.
9.5.14.2 Camera Configuration
On the left side of the WebCam property page, the list of associated cameras is configured.
Using the buttons above the list, new entries can be added, available entries can be sorted in
any order and unwanted cameras can be removed from the list.
The currently selected camera can be configured on the right side of the property page.
 Name: Name for this camera. This string will be assigned to string output data
points connected to the control, to indicate the name of the camera being viewed.
 Video Preview: Set this option to start a live preview of the currently selected
URL in the configuration software. The PC running the software must have
access to the camera. This can be useful to validate the entered URL and detect
any configuration problems early. To avoid delays when opening a page
containing a webcam control, preview should normally be off.
 URL: Used to select the type of URL to be configured. There are up to four
different URLs for each camera. The client will select and use the most
appropriate URL, based on its capabilities. When the drop-down is used to select
a different URL type, the text field below the drop-down will show the associated
URL and the preview, if active, will switch to this URL as well.
o Preferred Stream: Use this to configure the preferred video stream.
o Alternate Stream 1: An alternate URL, for clients which cannot
support the preferred stream. For example an MJPEG stream as an
alternative to a preferred RTSP stream.
o Alternate Stream 2: Similar to the above, a second alternative in case
the primary one is not supported by the particular browser running the
LWEB client.
o Fallback Stream: A last resort, in case all other streams turn out to be
unsupported. This could be a JPEG URL, from where individual still
images can be fetched. Something that any browser can do.
 Media Type: An additional hint for LWEB clients regarding the media type of
the specified URL. Even though the LWEB client can usually detect the media
type automatically, playback will start faster if the media type is already known.
For L-Vis devices, this option has no effect. Media type is always detected
automatically without any additional delay.
9.5.14.3 Stream URLs
Individual video streams are specified in URL format, similar to the address of a web page.
The basic format of a video stream URL is the same for all cameras:
<protocol>://[user:password@]<address>[/path][?options]
Parts in <> are required, parts in [] are optional. Here is a description of the individual parts
which make up the stream URL:
 <protocol>: A prefix describing the stream protocol. In almost all cases, this will
be either http or rtsp.
