Where to find LPR log file location?
AnsweredI am using NX with an ANPR camera which has an Event rule created for every time LPR (License Plate Recognition) recognises a license plate. This event rule write this to the log.
However, I would like to export the LPR data externally, if possible automatically. Does someone know where the LPR "Write to log" action is saved in the NX directory?
I did some exploring on my part, however, I have not been successful in locating the files, help would be very much appreciated!

Hi @...,
Please check the in-client manual:

Or the applicable Support Article HERE.
That being said, most people use the LPR events to create bookmarks, which allow you to play back and download the corresponding footage easily, and these will be added to the Event Log as well, without making a separate rule for it.

Hi Norman,
Thanks for the quick response.
I have already read through the client manual and support article you have linked. However this still doesn't answer my question, this only shows how to view the logs within the NX Client app.
I just want to know where the actual log for these events is getting saved on the server so I am able to export these logs.
Are you able to help me further with this?

Hi @...,
The event logs are stored in the mserver.sqlite file.
These can be found at the following locations:
C:\Windows\System32\config\systemprofile\AppData\Local\networkoptix\mediaserver\mserver.sqliteor
/opt/networkoptix/mediaserver/var/mserver.sqliteThat being said, we don't recommend and don't support fiddling in the sqlite databases.
If you want to do something with the event log outside the client, we do recommend using the server API for this.
You can use the following API call.
/ec2/getEvents
Please, check the server API for all available parameters.
