I have built 3 BI systems. My house with 12 4mp cameras, a school with 34 4mp and 2 4k cameras and a Church with 32 4mp cameras. All have been i7 machines and function flawlessly. Our Church is moving and would like to set up a new system with around 40 cameras (mostly 4mp), but they have 2 servers that they are "getting rid of" which I quickly claimed. 1 has an i7-7700@3.6Ghz and the other has and AMD Ryzen 5 3600X. There is also a Nvidia GTX 1660 Super video card.

Any recommendations on which processor to build with?

Doesn't quicksync give you some extra processing with the i7 even if using substreams?

Around the time AI was introduced in BI, many here had their system become unstable with hardware acceleration (hardware decode) (Quick Sync) on (even if not using DeepStack or CodeProject). Some have also been fine. I started to see errors when I was using hardware acceleration several updates into when AI was added.

This hits everyone at a different point. Some had their system go wonky immediately, some it was after a specific update, and some still don't have a problem, but the trend is showing running hardware acceleration will result in a problem at some point.

However, with substreams being introduced, the CPU% needed to offload video to a GPU (internal or external) is more than the CPU% savings seen by offloading to a GPU. Especially after about 12 cameras, the CPU goes up by using hardware acceleration. The wiki points this out as well.

Plus substreams opens up the possibility for older machines to be just fine, along with non-intel computers.

My CPU % went down by not using hardware acceleration.

Here is a recent thread where someone turned off hardware acceleration based on my post and their CPU dropped 10-15% and BI became stable.

But if you use HA, use plain intel and not the variants.

Some still don't have a problem, but eventually it may result in a problem.

Here is a sampling of recent threads that turning off HA fixed the issues they were having....

No hardware acceleration with subs?


Hardware decoding just increases GPU usage?


Can't enable HA on one camera + high Bitrate

And as always, YMMV.

Interesting....

I am running BI on an old E3-1245 because it has Quicksync. I am using substreams but kept the hardware acceleration. I have not noticed any instability since I moved the OS to a SSD.

I have another server running an old E3 without Quicksync. That runs Homeseer/HomeAssistant and a bunch of other apps (Mosqutto, etc) on docker.

And I have a NAS with 24 drives for ZFS. I actually used that and an Orange Pi for Codeproject.

I also got a N100 to run plex. That runs well on Quicksync.

I'd love to build one machine and run BI virtualized again. I did that initially but had to break it out onto its own machine at some point as I added camera.

Maybe if I got an i9 processor, I could accelerate Plex on the Quicksync, get a NVIDIA card and use my Coral.AI for Codeproject and then just run Blue Iris in VM Ware or something. Consolidating might make my life easy...

Like I said, many are using it without an issue, but I linked several threads where people were using Quicksync and disabling it stabilized their system.

Everyone has different computers with different parts, etc. so it may work better on some than others.
