If they had one of these capable of reading out to 100' to 120' I'd be very tempted to purchase one.
Perhaps next year.

Only when a porch pirate hits a legislator's porch and no one could capture the image of the nice vanity plate will this trend change.

Gotcha 3M Printed Plates at Night - LPR
As many of us have experienced, and well documented in this thread, that the 3M printed plates, especially those with blue in them, are very difficult to get with infrared. Unlike the stamped/raised plates, these printed plates do not have the same reflective properties and the flat nature of...
We will invite @wittaj to do this testing,
It can capture 120km/h car license. Hopefully it's a nice one on this 730nm one. The sample i wait around 2 months. This week can be ready.

Do you have a model number and/or possible price point on this camera? I may be upgrading one of my Z12's to the S2 and another Z12 to either the S2 or to a Z4 S3. I may hold off if a better option is coming soon. You described it an an ANPR camera. Is it a proper ANPR camera with ANPR functions or would it be a camera that can also be used an a plate reader?

Thanks. That was one of the results when I searched for dahua anpr 730nm ir. But I got to this thread late and I'll admit I didn't read all 300+ previous posts.

I would much rather see a 730nm or warm white light version of the -Z12E camera. A friend of mine has tested the built-in ANPR function in the Dahua ITC413-PW4D-Z3, and found that external LPR software (i.e. Rekor Scout) did a much better job of reading plates. He was completely unimpressed with the built-in ANPR functionality.
What is needed is a "dumb" 730nm / warm white LED camera with a good sensor and plenty of optical zoom, and without the built-in ANPR. A modified -Z12E would be much cheaper and far more practical. Let the end user deal with LPR functionality if required.
Just noticed I had some extra letters in there, didn’t mean to say “linked to”
from the descriptors so far it’s a possible candidate

I do a rough testing indoor. found this camera also can watch clear on the computer's screen at night time with 730nm, The NEW ANPR have really big IR light, so for professional IR camera, this one should be great.

He already did and reviewed here:

My choice right now is either to wait for a new camera with similar zoom as the Z12E or get an IR White Light Illuminator from Raytek or Axton to read the TN tags. Is there such a camera in the works?
Sorry for bumping this old thread, but I wanted to inquire here if anybody had found a confirmed solution to addressing the IR issue with some LPR cameras picking up the 3M printed license plates, like Tennessee.
I saw comments about different IR wavelengths being a potential reason, but before I made an investment purchasing an IR blaster I guess I just wanted to post here and see if anybody knew exactly what type of IR wavelength was needed to get an accurate read. I tried to get capture in Color, but unfortunately, there's just not enough light to produce a good clear image. Regular stamped plates work like a charm, but those pesky 3M plates are a real thorn.

Currently the only two options are a camera that works with 730nm IR or a white light illuminator.
Thank you! The 730nm IR is what I was looking for. I had seen some discussions about the different IR types but wasn't what had been confirmed. Ill check out the 730nm and see about making an investment for those.

Thanks. I just got to looking and realized that you don't seem to be able to buy an actual 730nm IR blaster
. Unfortunately I already have 3 LPR cameras we purchased, about $2k each and didn't realize that they didn't like Tennessee's license plates.
