I have several DCS3716 located around our factory. Some of these are used for a live view of mechanical processes.
I am connecting these cameras on a Debian host running VLC on an RTP protocol. The local switch is a HP J9562A.
There are frequent and recurring drop outs from the cameras that are causing freeze screens or black screens on the output client. VLC is set to reconnect a dropped connection and performs fine in test situations, but not in the real world. Having frequent complaints about having to restart VLC to resume the feed.
Here's a network monitor graph of what's happening
over 2 days
and you can see clearly over 2 hours, of an individual incident
As you can see the network isn't dropping completely (which would actually be preferable), but just enough to ruin the connection with the viewer.
I have 4 cameras all behaving the same as this
Any suggestions on the cause of this please?
