Thanks for the response, Sebastian.
We set up access via the CVB Management console as follows;
Device Configurator -> Advanced Config -> find the correct filter driver (based on the target camera MAC address) -> add to the ‘CVB CamPort Assignment’ section and then hit ‘Save Configuration’.
‘Auto switch enable’ setting has not been altered.
It may be a ‘red herring’, but one of the engineers has reported that he thinks the issue relates to powering the camera with a bench lab supply (24V) whilst connected through a non-POE ethernet switch. We’ve just started to connect the cameras to the main network directly (using POE only) and the issue seems to have disappeared - at least over the past couple of days.
I’m not sure that the switches were the issue since the ‘disconnected’ target camera could still be streamed from by other users on the network.
I’ll keep you posted if the issue returns…
