Today make a visiting at CPSE, the biggest exhibition about security products. Here are some of my thinking after the visit. 1.Dahua and hikvision lanuched some new cams,but these 2 big companies focus more and more on the cloud platform, esp for intelligent video analytics. 2. The AI tech has...
Ultimate question is, how will this perform in low-light?Dahua will release a new 12MP camera, same series as IPC-HFW7442H-Z.

Arjun, take a look at the night video shared in post 3 (initial night video), it performs very well and is a nice bright lens even with minimal lighting as I show there with the cars and deer shots.
@Davahad
I didn't want you to think I'd forgotten about your question. The answer is really in what you want to see as an output and where you pull the data from.
For example, in camera you can pull, hourly, daily, monthly, yearly counter type reports in Bar or Line Chart as I show below when using Video Structuralization (counts Vehicle, Non Motor Vehicle, People etc and you can select what you want to report on)
You can also do the same for ANPR but again as the Video Structuralization captures more statistics I would advise using that instead.
Either way both charts can be exported as a BMP picture only.
Now if you move to an AI NVR then you can only pull 7 days BUT gain a LOT more. Specifically you can export to a CSV file like below (removed plate numbers for privacy) and choose the amount of information you want to see. You also get a download folder that contains all vehicle and plate captures in JPG for the same period). This is great because there is an embedded hyperlink in the spreadsheet that when you click brings up the associated image. It can do this for the full res, close up and plate views, I just removed those from this export and only used the wide, full res pics.

What AI NVR are you using? What about the firmware update for the older models? The 5216 Pro Series has the ability for some AI now thanks to the NVR 4.0
@Arjun , I'm currently testing the...........5216 pro with NVR 4.0 loaded for the AI features 
Will be working on a review of both the HW and the FW soon as well 
Will be working on a review of both the HW and the FW soon as well Awesome, that means existing owners don't have to upgrade to the recently released AI NVR's.
@Arjun , I'm currently testing the...........5216 pro with NVR 4.0 loaded for the AI features
Is 4,0 stable now? I loaded 1st version but then stopped getting push notifications and reverted back to 3.X
Yes you can. Now in answer to your other question ‘is it stable ?’, there are still a number of quirks and bugs that need ironing out (I’m building a list to have sent to Dahua) so yes you can use it and it is functional but you may find certain elements don’t work as expected or at all currently.
The good news is FW is coming at least once a month and personally, I’ve found the power and feature set of NVR 4.0 (vs 3.0) worth the upgrade especially with AI cams. Will post more details when I do the NVR and OS review.

Thanks. I am going to order the IPC-HFW7442H-Z4 with the 32x zoom and will let you know how it works for license plates, car counting, etc.
I’m going to move the cam and post more LPR shots soon so you’ll see how it performs when setup at a more LPR friendly location. This will be in line with my 5231 & 5241 LPR setups.
The Z4 version will certainly allow more flexibility on install location with the 8mm to 32mm than the standard lens and depending on your location, distance to target, choke points etc will impact the end result.
The Z12’s I mentioned (5231 & 5241) above allow for even tighter image and further flexibility with the Z12 of the 5241 being part of the Pro AI series (human and vehicle detection only but no ANPR or Video Structuralization) series but at 2MP. I think you’ll be happy with the 7442 but msg me directly with install location details and will help with tips / tweaks if you’d like.
I intend to mount this 7442 as close as I can get to provide a similar comparative LPR image for all here.

I have the HFW5241EP-Z12E and it is working great with OpenALPR day and night. I added a separate Axton IR Emitter MGPXL AT-11E-S PoE IR ILL/850nm/20x10D to help as it is a long distance away.
So I noticed car flashers in video which did not prevent capture, kewl. Too much snow for this Southern Boy
, have a friend up in the mountains of Bailey, Colorado that pretty much almost every morning during winter had to snow blow driveway just to go to work. I think I would get a job where I worked at home Thanks again for video/info...hey David, to clarify, every car in the video resulted in a capture even with the flashers. Just dial in HLC OR set exposure high enough to compensate. I wasn’t quick enough to pull some of the close up pics before I formatted the drive but every vehicle I show got an ANPR hit across all videos. Hope that helps

On the AI NVR you can setup B/W list with alarm outs for each. .What is really cool is that you can also PT activate from your AI LPR cam when a blacklisted or whitelisted vehicle is detected. For example AI LPR picks up blacklisted plate, PTZ activates to set location and tracks from there. So although PTZ activation through NVR's etc is not new, doing this on plate detection is really useful.
