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 every second or so...
Any suggestions?
