OpenALPR Webhook Processor for IP Cameras

Well, I'm not sure this will ever finish

Current db size is 1.44GB, size when I started was 1.30GB. So we've done a 140MB in almost 6 hours

Given over 100GB of plates, I'm in trouble!

CPU isn't really even being used. I wonder if the limitation could be on the Rekor Scout side?

Here is a snippet of the log. Is that HTTP GET for the scrape? Looks like thats 120 seconds to respond!

 
Awesome project. Will likely contribute if you're open to PRs (and reading through the thread, it sounds like you are)! :)

Few questions:
1) If you run the Rekor web server locally, are you able to run this without opening any ports to the outside world?
2) The latest agent config software [local/desktop Windows] has 4 'destination' options -- including what I assume is 'direct' [LAN] access to the data in the Beanstalkd queues. Is there any reason not to use this instead of the webhook? Both for performance, speed, and in the interest of keeping everything local. Or is that option not available for the cheap $5/mo plans, maybe? [I'm on commercial trial atm].
3) Is there any data that is added/augmented [by Rekor] after local computation, on their server? Or is everything happening locally, their agent ships to their server, and then you're grabbing from there?

Bonus:
It took me a bit to get things setup -- some of the posts here reference old UIs/options & I didn't stumble on the GH wiki til I nearly had it all working. I had attempted to 'scrape' several times before I had a working config. Now when I hit scrape, I see the 'toast' message saying scraping started, and then it's immediately followed by a 'scrape finished'. Logs show the epoch it searched. I definitely have data (both local & remote [on Rekor's dashboard]) that didn't get imported, though. Is it date-range matching, and my "oldest scrape time" is making it fail to see older stuff? If so, where is that value stored/how can I reset it -- else, any thoughts on what might be causing the issue? New plate scans are coming in & no errors in log after running scrape; all is configured including my cameras & matching IDs, etc...

Awesome stuff. Very curious about #1 & #2 above -- if #2 is an option on the $5/mo plans then I'd likely volunteer to write the code to have "poll Beanstalkd queue/tubes" to parse the data directly via LAN -- though if that's not an option for $5/mo plan users then it's probably not as useful to add.

Thank you!
 
If you run the web server locally you don't need any ports. Most users are using the cloud version though, so they need the ports open.
I have never tried reading from beanstalkd directly, you are more than welcome to try.
 
Anyone noticing performance issues with large plate counts? I'm at around 242,000 plates, and lately the statistics are taking around 15 seconds to show a lot of the time, some faster, some slower. I'm wondering if I could be starting to get to the point where I have too many entries?

Running in Docker on Debian, dedicated VM for this. 8 Cores of an E5-2680 V2, 2GB RAM, all NVMe storage, 10G Networking. CPU load doesn't really seem high at all when loading plates, and memory is sitting at just 800MB used of 2GB
 
I noticed this also, having all of the possible plate numbers for each group in a single string is having performance problems once enough plates get into the database.

Try out v4.2.2-alpha6 with optimizations for this. You need to back up your processor.db file beforehand, this release has an irreversible database migration to increase performance. It might be a few minutes before the application will be functional once it starts, the migration takes a while. Monitor the logs and CPU usage to tell when it's finished.

Awesome, thanks!

Will latest get it, or do I need to specify v4.2.2-alpha6?
 
Woweeee, this is FAST now

Didn't really take any time for it to be functional, must have been super fast
 
go to v4.2.2-alpha8 this fixes an issue where lots of incoming plates cause the browser to constantly refresh the list and fixes an issue with processing alerts
 
Thanks I'm on it, never had enough cars to cause the other issue that I noticed

Is there a similar tweak that could make the main page load quicker? I've noticed as more and more plates go in, the slower it goes
 
When doing scrapes, are plate images still being pulled or is there a way to "opt out"? I stopped scrapping because I didn't want to have duplicates of plates (Rekor and your program). Too much drive space needed.
 
i could add a default date/time filter of 1 month, currently the pagination counts the total amount of plates that apply with the current filters applied. if i set the timeframe to 1 month it returns much faster.
 
v4.2.2-alpha14 sets the default date range to 15 days, which should speed up the list query.
 
v4.2.2 is released with searching optimizations.
  • default filter date is now 15 days in the past to increase searching speed by not reading entire database.
  • database optimizations with possible matches for increased searching speed.
  • fixed some edge cases with lots of vehicle being recorded causing the UI to refresh too much.
  • cancel ongoing searches when a new search is triggered.

I'm installing fresh on a new machine and I can't seem to add a camera anymore. I hit the "add camera" button, plug in my stuff, but the camera never gets added and the "add camera" button dissapears. Have to delete the .db and start over by hand in order to get the "add camera" to reappear.

Hm it's working fine for me. can you send me a screenshot of the fields you are populating when you add a new camera? that might have something to do with it.
 
Odd. I'm just hitting "Add Camera" and then inputting the Manufacturer, Model, IP address, username, and password. Leaving everything else blank for now. As soon as I hit "Save", that window goes away and the "Add Camera" with a plus button is still there. However, if I navigate away from the camera page, and try to go back, the page is blank. I can't add a camera and I can't see the camera I added. I have to hand delete all the processor.* files created in my config directory and then restart the service to get everything back to baseline. Tested with both Chrome and Edge.

Are these errors normal?

Code: 
Your application is running in Production mode, so make sure it has been published, or that you have built your SPA manually. Alternatively you may wish to switch to the Development environment.
System.InvalidOperationException: The SPA default page middleware could not return the default page '/index.html' because it was not found, and no other middleware handled the request.

@IReallyLikePizza2 If you get a chance, can you spin up a new VM and see if you can start from scratch (no user.db or database.db) and see if you can add a camera? I'm dead in the water here until I can figure this out.
