Our i-PRO camera with Vaxtor application on camera has function to detect license plate and send the data via Analytics event(XML)( or json format).

I understand these data can be used on Alarm manager tab on Smart client but black or white list of plate number cannot be created on XProtect server side without any plug-in software.

​

Can these plate data (sent by analytics event) be used on XProtect LPR add-on ?

If possible, I would like to know if registration to black/white list and matching plate functions can be used or not.

Yes, it is possible to purchase one license of Milestone XProtect LPR and then send the Analyitcs Events from you application or device mimicking the same format.

Thank you for answer. I will try to use.

In this case, LPR server detect license plate from video stream on server side and there is no meaning in detecting on camera side. Is my understanding correct ?

If you purchase and use Milestone XProtect LPR for all your Camera/LPR channels the detection is done by the Milestone LPR server and there is no need for the detection in the cameras. What I was proposing is that you buy one license so that you can have the Smart Client LPR tab, the white lists and other functionality, but let your cameras do the detection and deliver the analytics events. You will have to have minimum one license of LPR to have the functionality, but you could use many of your cameras as you would not need the detection server functionality. I hope it makes sense.

Thank you for proposal. It makes sense.

In that case, is one base license for XProtect LPR enough ? Or both one base license for XProtect and 1 LPR camera license required ?

The base license of XProtect LPR should be sufficient in this case.

I started thinking…

If you are a Milestone partner you might be able to get a test license, at least you can ask. In that case please write to partner@milestonesys.com and ask.

If you are not a partner maybe have a look into it.. https://www.milestonesys.com/partners/become-a-partner/technology-partner-program/

Thank you for support. We have got test license and confirmed.

​

What was worked as expected.

​Detected plate on camera side were shown on LPR tab without camera registration to LPR server.

​What was not worked.

​It was not possible to display only matching plate events on LPR tab for plates in the matching list registered on the LPR server even if we register the same camera to LPR server and configure “Math lists”.

Analytics Event that camera sends

We found that “LPR Event” is important so that LPR tab show the event and is used for Country in LPR tab.

Our estimation

Plate match processing on LPR server side cannot be applied for plates that camera side detect.

Is our understanding correct ?

8

In the RestAPI and in the Configuration API there is functionality to handle LPR Match Lists.

https://doc.developer.milestonesys.com/mipvmsapi/#operation/getAlllprMatchLists

https://doc.developer.milestonesys.com/html/index.html?base=gettingstarted/intro_configurationapi.html&tree=tree_4.html

There is a known limitation that the Config API Client sample and the strongly typed Configuration API - VideoOS.Platform.ConfigurationItems classes - cannot work with the LPR Match Lists.

Unfortunately, this means there is no sample that can show you how to work with LPR Match Lists. I hope you will be able to make it work.

More importantly, if you do not use the Milestone LPR, you need to be aware that when you submit the analytics event it is not put through a process that detects whether a match list is matched. It is the other way around. You can read the match lists as per above, then you can trigger the match list event at the same time as you submit the analytics event!

I understand

- XProtect can have matchinglist database and we may manage the list via SDK

- Matching process itself should be done in another software, not XProtect side when we do not use XProtect LPR server side processing.

Thank you, all clear for me now.
