RTSP and multicast streaming
There are different ways for a client to receive a multicast stream:
the client can connect to the camera and request a multicast stream. In this case you would see a connection in the dashboard.
If not checked, it requires at least one connected client to have the camera provide the stream into the multicast group. Clients who just joined would receive no stream if there is no client connected.
the client can join an existing multicast stream without connecting to the camera. It must know the multicast group. You would not see this client on the dashboard.
The streaming flag tells the camera if it should feed its stream into this multicast group, regardless of a connected client. This is an option if there are many, many clients possibly connecting to the same camera/stream.
There is no difference in data amount if streaming is checked or not as long as there is at least one multicast client connected to this multicast group.
Below you find a way how to pass a special connection string to request a multicast stream via RTSP from a BOSCH IP camera or IP encoder.
