MP/s of my system and are there any concerns with adding?

[Ri22o]

I saw MP/s mentioned the other day so I decided to look into the Wiki to calculate my system.

I am running 32gb of DDR4 ram with an i7-10700K using Quick Sync (benchmark is shown as 18,998). I think I have a memory leak and need to update the driver, but memory is typically 42-50% and CPU is 5-7%.

Using the chart below, I have calculated my MP/s at 1,808 with full resolution, and 162 at D1. Multiplying by 10 (per the Wiki) puts my full resolution at 18,080. Do I have any concerns with my system or adding additional cameras? Is this all nothing to worry about since I use sub streams? Just not sure how to interpret the info from the Wiki.



30fps
(2) 2MP

15fps
(1) 4K
(1) 5MP
(23) 4MP
(2) 2MP

10fps
(2) 4MP

The MP/s numbers in the wiki are dated and before substreams were available.

People are running 50 cameras on 4th generation CPUs now with substreams, so on your 10th generation you will be fine for a long time lol.

If you turn off subs then it would start becoming an issue or use BI AI on lots of cameras.

Much of the answer depends on whether you will be using CPAI and on how many cams and how often they are generally triggered simultaneously.

That's what I thought, but wasn't sure.

Currently using CPAI on the two LPRs and person detection on one that gets a lot of vehicle traffic. I will see CPU spike to 90%+ at times, I am guessing it's the camera running person detection. I would like to use it on more, but I don't think it's necessary on more than a couple.

There is nothing wrong with it spiking. Also CPAI is coming along with Coral and Orange PI integration so you will be able to cheaply add AI processing power.

Should I update the drivers? I saw this in regard to the memory leak.



And this is the driver on my machine.
