IPC-Color4M-T: got a false positive with IVS, what should i tweak?

[pol]

Hello all,
I have some IPC-Color4M-T configured with: MD/SMD off, AcuPick off, IVS on, large scale ai models on. For IVS, I have just a basic intrusion rule with appear/cross for human and/or vehicle. Up until yesterday night, everything has been working beautifully. I have some cats running around and some big birds/whatever I don't even know the Italian name let alone the English one
I never had a false positive in the past ~1.5 months (when I started using IVS) but yesterday night this cat triggered the "intrusion alert". I wonder why it happened and what I can tune what setting to avoid this from happening again.

The cat came running from the bottom of the frame to the top. Maybe because it was running/jumping fast it thought it was a human?

I'm using the latest NVR and camera firmware available from Andy's website. AI is by camera.

Thanks

Turn OFF large scale models and reboot the camera.
Go back and double check it is OFF

Ah cool, thanks I'll try that. Out of curiosity, what's that parameter purpose?? Thanks

AI mumbo jumbo that in theory is better more precise detection at further distances and can detect various animals by type.

So if you have a problem with Giraffes in your backyard it may be beneficial to keeping it on.

I suspect it picks up birds too

I see, interesting. Thanks a lot

I have disabled the large scale models. But still get the human intrusion when this cat appears.
It was walking slowly and video is very clear. No streaks or else.

Any idea what I could tweak?

Have you tried the global config or setting a min object size bigger than the cat?
