    Is there a way to adjust the threshold of the network issue reporting? Can you set the amount of packet loss required to trigger this event? The reason I ask is that we have a system with older Hikvision cameras that sporadically cause network issues "RTP Packet loss detected" but there is no loss of video to note. We need to monitor the true issues where significant packet loss is occurring to the point that there is video loss but don't want to be bothered with the ones that are very minor.

    Hi Matthew,

    We could change the RTP Timeout parameter, but in general, you will never eliminate the number of package loss, since the default setting already allows 10sec of the timeout, which is quite a lot considering the number of RTP packages per second.   

    In order to do this, we would need your cloud ID or the public IP address and port number that has been forwarded and server access on the admin level.

    Thanks Norman

    Are you saying that in order for a “RTP Packet loss detected" event to be generated it currently must fail for longer than 10 seconds?

    Hi Matthew,

    That is correct. The Nx Media server tries to retrieve the RTP package up to 10 seconds before it drops the package. In reality, this means that there are quite some attempts before the package is considered lost. 

    You could visualize this with Wireshark or a similar application.

    Could we possibly move this discussion to a support ticket that is not public, I would like to discuss my particular system details?
