Taking LPR database from dahua camera and exposing it elsewhere?

Getting the hang of it
Hi All

Does anyone know if this data can be exported to a file on another system or something so that it can be formatted/displayed in something like a home automation system? when using the Dahua LPR camera? I do not use a Dahua DVR.

I use blueiris.

Would it be best to look at something like the Dahua DHI-ITC237 and use OpenALPR? BlueIris runs on windows, so I could run the OpenALPR software on the same windows machine.

Thanks

Curious what you would use the LPR data for in a home automation environment? Receive text or email alerts from specific plates driving by? Unlock a door?

Gymratz and I are developing a Windows program to automate the periodic downloading of the OpenALPR data, and import it into a SQL database. A companion program will allow for viewing, filtering and correcting of the data. The programs will be open source, so that if you or anyone with coding knowledge wishes to can build upon it.

Ideally, id like to display the last 3 number plates on a web page as a JPG. And yes, receive alerts if the plate number is not white listed for example.

There's a number of varifocal Dahuas which will work well as LPR collectors. OpenALPR offers a free cloud tier with 48 hours of data. With our program you can download the data by the minute, hour, or day, etc. With a Pushover.net account you can receive text alerts on specific plates, and while the account is free, the app has a cost, and has a limit on the number of SMS messages it can send out per month.

Once the data resides in your own database then you can pull from the table with a query and embed the images as needed, but our program itself won't create a webpage as such.

With the OpenALPR cloud service, all JPG files are locally stored and accessible from the local server by the image's unique ID number (whose field name is 'best_uuid').

Here are some examples of rendering into a webpage:
strHTML = "<html><body><img src=" & txtIPaddress.Text & ":" & txtPort.Text & "/img/" & thisPlateID & ".jpg height=1181 width=2100></body></html>"
strHTML = "<html><body><img src=http://192.168.1.123:8355/img/" & thisPlateID & ".jpg height=1181 width=2100></body></html>"

I use the Z5 Dahua (IPC-HFW5231EZ5) and believe many use the Z12 model for a tighter zoom on plates.

Update: Should clarify that the OpenALPR software runs on the same Blue Iris PC.
