The NVR can store license plates It says " dedicated license plate capture camera". Does the camera B52IR-Z12E S2 work for the purpose?
TIA
TIA
Can I use this NVR DHI-NVR5216-16P-I with camera IPC-B52IR-Z12E S2?

No it does not. The Z12E is used by us to manually read the plates, but it is not designed as a plate camera.
You would need an ANPR or ALPR camera that can actually read and log the plates. Something like this:

Mini-Review - EmpireTech LPR413-Z3
Would this camera capture out to 120' or so? I have a 437 and would like to get this to grab plates from the other direction.

That NVR can do 'AI by device' functions, including 1ch 'video metadata'. In video metadata it does try it's own LPR detection.
I don't know if this would work at night when only the plate & headlights show on an LPC camera's image.
I use this function on a spotter camera (handy to search every human/vehicle/bike that has gone past).

Is there a NVR that works like how you do with BI for the z12e?No it does not. The Z12E is used by us to manually read the plates, but it is not designed as a plate camera.

I have not had time to check on metadata. Does it need lots of setting and fine tune? How well is it during the day?
What else did you do? Like what setting in the camera GUI? I tried this on my neighbors NVR and it never read plates.

I dont have the angle for plates on this camera, but because it (5442-Z4-S3) has MetaData capability, I can get other stuff with my 2018 5216-16P-4KS2E NVR.
Not so good on vehicle attributes, but again I think that's mostly due to the lousy angle, This camera is zoomed and intended for facial ID on the street

'Video metadata'.
Enable it for Human, vehicle, and non-motor vehicle detections.
When it detects a vehicle it does it's best to recognise the licence plate (as per the image I shared). But keep in mind this does not have the same 'trigger' thresholds like a dedicated LPR camera does, which means it might miss licence plates at night because the NVR does not detect the shape of a vehicle.

Mark does the camera you are using that one have Video Metadata enabled?
I had to enable it on the Z4 itself to get the stats and I think the database on the NVR under AI Search (non-AI NVR)

This is the '-I' NVR with built in AI video metadata.
For a person walking past, it will do face detection (NOT recognition). It does an okay job. A few times it double counts when there is loads of people.
Non-motor vehicles, bikes (& 'motor'bikes???). It got this one correct of helmet vs no helmet.
And you can see the 'AI live' at the right side of this video. And the thumbnail.

It works during the day fine. At night I think it would not work properly.
I don't use this camera for LPR. I enabled video metadata for this spotter camera.
