ANPR with HikVision DS-2CD4A26FWD-IZS/P
Completed
Hey All,
I'm using the above camera to do ANPR.
What information is passed to NX from the camera and can it be accessed as a set of variables?
As an example, push notification allows you to customise the header and body of the message. Is it possible to include the read number plate in the custom message? something like this... "Number Plate %NUMEBRPLATE% seen"
The other idea is to be able to include it as a variable in a HTTP request. The idea being each time a number plate is read it does a HTTP request to a website that checks the number plate to see if it has been reported stolen?
or the ability to use HTTP Request to write the number plate to a file with the date and time.
Thanks
Grant

Hi Grant Watson,
Currently, Nx Witness does not support sending the license plate number through the notification. This feature requirement has been noted, however, I am not able to provide any firm schedule or whether it will be implemented so far.
In the meanwhile, we suggest using the bookmark to record the time when the event occurs, you can also review the bookmark to get the image and the license plate number. Please refer to this support ARTICLE for further information.
Thank you.

I don't know if you have an Analytics event in the Event Rules for this camera or if it can send HTTP requests. But we do have some variables for the Do HTTP request action, but only Analytics events and Generic events might generate the variable output.
The placeholders syntax is:- {event.caption} is replaced with the event caption (the string is shown in Desktop Notifications);
- {event.description} is replaced with the even description (the string is shown in Desktop Notifications);
- {event.cameraId} is replaced by a corresponding camera guid;
- {event.cameraName} is replaced by user-readable camera name, it’s skipped if for some reasons server doesn’t have a valid camera id (e.g. when the event was created by incorrect API call);
- {event.eventType} is replaced by internal unique event identifier (e.g. “nx.stub.lineCrossing”);
- {event.eventName} is replaced by human-readable event type (that’s the value shown in rules configuration widget, e.g. “Line Crossing”), it’s skipped if eventType id is incorrect.

So if the LPR number will come to Nx as a part of Generic Event (caption or description) -- it will be included in all notifications. Custom text can be configured on the side of the integration (so you'll need to send to Nx "Number Plate %NUMEBRPLATE% seen" in Generic event).
Also, if LPR is present as event in Event Rules -- then you can configure a rule Analytics event -> Send mobile notification, and it will send a default text, but it will include camera name and license plate number
