Context:
3 IP cameras using one point-to-point Ubiquiti radio link.
1 camera is a Dahua IPC-HFW2431S-S-S2 (4MP) and the other 2 are cheapo Nivian cameras (5MP) which will be replaced soon with decent cameras.
All cameras running at 15fps, keyframes 15, H264, the Dahua at CBR 6144, the other two around VBR 5120 as they cannot handle any better.
The Ubiquiti link is not saturated. It is running at around 14-16MBps with a capacity of 100MBps+
Issue:
If I run the Dahua alone, the fps is quite stable. If I run all three cameras at the same time, the fps on the Dahua becomes unstable, oscillating between 8 and 24 fps... it's all over the place. The cheapo cameras stay stable...
Additional considerations:
I have other parts of the property running a mix of Dahua / Hikvision cameras on the same types of link (or even worse, as one end is a WIFI access point and the camera end is the Ubiquiti, so not a dedicated point-to-point) and for all of them the fps stay stable for all cameras
Any thoughts?
Could there be something in the network configuration / behaviour of the cheaper cameras that interferes with the stream from the Dahua?
I have tried all sorts of changes in config on the cameras but the problem is still present.
I suppose I could try to move a couple of the other Dahua/Hikvision cameras and temporarily use them in place of the cheapo ones and see if all goes back to normal, but quite a bit of work to move everything around.
