kmax1940 0 Posted March 27, 2015 We just installed a new Dahua NVR at a school. The NVR loses its network connection every second or so when connected to the schools gigabit network. We know its the NVR losing network connectivity because we can ping the NVR and see it dropping. When we move the NVR and camera off the schools network and on to our own gigabit network the nvr and cameras work fine with no drops. The strange thing is that when we put an OLD model of dahua NVR on the schools network... It works FINE with no problems. We have tried a couple of the new model NVR's and they both do the same thing.... dropping network connection. Any suggestions? Share this post Link to post Share on other sites

jazzar 0 Posted March 30, 2015 do you have enough bandwidth available on the school network- maybe the cameras are pushing it over its limit ? could you have a duplicate IP address assigned to the NVR ? Share this post Link to post Share on other sites
