I've set up a 9-camera system, using the Dahua 4300S series, along with some of the newer Dahua 1320S cameras. Individually, each camera works just fine with Blue Iris. However, when all the cameras are running, the data rate for one of the cameras will drop down to almost nothing, and often the other 3 cameras on that "leg" of the system get pulled down as well.
I'm trying to run the system at 15 FPS, using 1080P resolution, and for the 5 cameras on the other leg, it runs just fine. I have checked and changed cat-5 cables (a pain, because they run through the attic), I have swapped the POE switches, and still it simply doesn't want to run nicely. Oh, and I've tried reducing the resolution and frame-rate on all the cameras, but the problem seems to be unaffected by that change.
In the status window, the "good" cameras are running at around 240 kBps, the "pulled down" cameras at around 60 kBps, and the "problem" camera at around 6 kBps. Of course, if I run that camera solo, or with the 5 cameras on the good leg, it typically shows the 240 kBps.
I am using powerline adapters to get the network connection to the POE switches, but that doesn't seem to be causing any bandwidth limitations, as I'm able to stream HD video to my television and run other computers on the network with zero issues.
Another symptom... as soon as the problem camera switches to IR at night, the data rate drops to nothing... nada, zilch for that camera, and the other cameras on that leg get pulled down to much lower data rates as well.
And a curiosity... If I use the Dahua SmartPSS software to monitor these cameras, I do not have the problem at all. The problem camera behaves nicely, and the others on the leg perform nicely as well.
Does anybody have any clues as to what is going on? I suppose I could try to figure out how to fully configure the Dahua SmartPSS software, but it's documentation is difficult at best to understand, and I'd much rather continue with Blue Iris. I'm reluctant to buy a replacement camera for one that works pretty well by itself, but that may be what I need to do. I just hate doing the thing with replacing stuff until it all works.
