Be more specific?
Are you looking at taking a camera and tweaking settings to be able to visibly read the plates but the system cannot log the actual plate numbers or are you meaning a camera that can read the plates and log the plate and store the plate information?
If you have a NVR that can read and log plates, that is one that has ANPR, but you also need a camera that has ANPR for it to work.
If you are looking at taking a camera that you can tweak the settings to be able to visibly read a plate but cannot do anything about it like log and store it, then a third party solution to log and store the plates is needed like OpenALPR or Plate Recognizer.
Or you can go with an analog system as well that is capable of reading and logging plates.
Regardless of the answer, the camera still has to be tweaked for LPR duty and as such, it cannot do double duty like be an overview camera and read plates. Maybe in the daytime you can get away with it, but not at night with the shutter speeds needed to read plates unless you have a crazy ton of light like the toll booth cameras with plate readers.
