The camera overview view has substantial lag for some cameras. Viewing individual cameras fullscreen works, with virtually no lag. The last individually viewed camera seems to retain the no-lag, but the other camera lags about 10-20 seconds. This seems to be a bit random, which camera and for how long. When I just configured the camera it's faster but after some time it lags again.
  • 1x 4MP and 2x 8mp Hikvision camera's.
  • Gigabit POE Switch.
  • Computer: Threadripper 16 core 3.8Ghz with 64 GB Ram and NVidia GTX 980TI
I have already tested multiple things:
  • Set all cameras to H264 (non-plus)
  • Directly connected the POE switch with the cameras to BI PC.
  • Lowered bitrate of the Cameras.
  • Increased and decreased buffer size for cameras.
  • Changed hardware-accelerated decode to 1) No - 2) Default - 3) Nvidia
None of these things makes much difference.

Yes I meant within the camera itself.

Do you use substreams and what version of BI are you using?

The latest version of BlueIris. Substreams are enabled in the camera web interface but I don't use them.

I thought at first that the network may be has too little bandwidth, meaning 2x 4k streams would be too much. But that makes no sense. Lowering the bitrate does not solve it or improve it.

I chased a problem a bit like this, delayed frames from cameras, and delayed frames on UI3.
I changed the switch to one that could handle more packets, no help, It ended up being the linksys router.
Even though all cameras and blue iris was on the same gigabit switch, after the change to a newer
router, things smoothed out.

What router do you have now? I have a Netgear Nighthawk R7000.

I dropped an ubiquity Edge router-X in, then ran the old linksys
without DHCP, just for the wireless.
There are threads on setting up a Edge router-X on here, also
some good videos on you tube.
 
I would first try fenderman's suggestion. He forgot more about blue iris then I know.

The nighthawk is a good router when it works, but lately we have had some that developed
intermittent problems, and would have to be rebooted to fix it. This is not a big problem for
residential use, but in an office environment did not work.

I did this at a customer location, so used a "pro" router that I could use for VPN also.
It is a basic router only, is not the most user friendly, but works very well.
I would probably not recommend it unless you have some network experience,
or if you want tl learn new stuff. $61

They you would either use your old wireless router for only the wireless, or add a access point.
