Thank you for your guidance. I will get busy ordering the NVR5216-16P-4KS2E then. I was told it was a good NVR so seems worth the investment. I am holding of ordering another Z4E as I am sure I read a thread from Andy implying new 2021 Camera range is imminent, so may be worth holding of just a while longer .The Z4E does not have ANPR capability, but the NVR does. Both need ANPR capability for it to work. But with ANPR capability, then you don't need a 3rd party solution like OpenALPR....(well many here that have ANPR capable systems say that the 3rd party apps are more accurate).
The Z4E is certainly capable of being configured to then use a 3rd party like OpenALPR or Plate Recognizer and many here use that camera for LPR purposes, but then at night all it does is plate reading due to the fast shutter needed. If you can get the right angle to I think it was around 60 feet or so (might be a little more), then it certainly is possible.
