Correct; AI Port treats every ONVIF device the same

Unifi AI Port- Works great!

Nice! How many ONVIF devices can it support at this moment? Also, is there still an issue with the capture of plates after dark?

That was a surprise to me when I got the AI Port, that it need not even be connected to a camera, it just needed to be on the network. I have 4 ONVIF cameras as well as the G4 on the Protect. The use of plate collection, though, is weak even during the day. My Z12 is also on Blue Iris, and I have a Rekor account for collecting plates, and the Rekor captures most while the AI Port can miss maybe half. The AI Port would be useful for a business where the camera is directly in front of the cars, say, in a corporate parking lot. But for LPR, I am staying with BI and Rekor.
Thank you for sharing your experience. I was contemplating buying one but I'll have to pass for now if it is only capturing half the plates compared to the Rekor.
I ordered the AI Port to evaluate its performance and paired it with an Axis P1468-LE 4K camera. Vehicle, person, and license plate recognition work very well, but face and animal detection leave a lot to be desired. One thing that really surprised me is that the maximum supported recording bitrate is capped at just 8 Mbps (see "Video compression" in the attached screenshot), while the camera actually streams at 20–30 Mbps. Is this a bug on my end, or are others experiencing the same limitation? Overall, I'm quite happy with the product, but this could be a dealbreaker for me.

It also seems that the AI Port itself can’t process a stream at 20 to 30 Mbps. I hadn’t noticed it at first, but after reviewing some of the recordings, I realized that many of them have brief skips—usually missing about a second of video. I compared them to recordings made at the same time by Blue Iris, and those didn’t show the same issue.
I can imagine plates just slipping through the cracks due to bad bitrate
Thanks for pointing that outLicense plate recognition has actually worked really well for me with Dutch plates. I reached out to Ubiquiti because I find it hard to believe that the AI Port only supports an 8 Mbps output stream—it seems more like a bug to me. Unfortunately, their support hasn’t been very helpful so far.
I was hoping someone else here has tested a 4K camera and managed to get higher bitrates. Anyone?

I've been in ongoing communication with Ubiquiti support over the past week, and it turns out that the AI Port only supports a maximum bitrate of 8 Mbps. It also transcodes the incoming video stream into a different format for the outgoing stream. This means that the high-quality video from my Axis P1468-LE is significantly degraded when recorded by Protect. Needless to say, I ended up returning the AI Port.
it looks like now is possible to do 4 cams at 4MP (2K) (like 5442 or 3449) or 2 4K cams at once on one AI Port (199 USD or 222 EURO)...
EDITED:
But I had read one more time the changelog and found that is about UI cameras not ONVIF ones
So we need to wait for another firmware update with multiple ONVIF cam support...

You can create a stream profile in the Axis camera for the AI Port and use Maximum bitrate instead of variable. When you choose Maximum for bitrate type, you can enter the maximum bitrate as 8 Mbps. This will only affect devices using that stream profile and won't affect BI. Also, if the P1468-LE is normally streaming between 20-30 Mbps a settings is off. Normally, mine is between 2-15 Mbps depending on how busy the scene is, where it only jumps to 15 Mbps momentarily. I would only see the camera streaming at or over 20 Mbps when the entire image is filled with moving objects such as a heavy snow storm.
You can have multiple different stream profiles that have different bitrate settings with that camera.
Yeah, I’m aware that I could set up an ONVIF stream profile on the Axis camera with a max bitrate of 8 Mbps. But honestly, that kind of defeats the purpose of investing in a high-end camera like the P1468-LE. I want the camera to be able to use the full range of its encoding capabilities and push up to 15–20 Mbps when there's a lot of activity in the scene. Capping it at 8 Mbps just to accommodate the AI Port feels like I'm nerfing the camera’s potential.
