OpenALPR Webhook Processor for IP Cameras

[tech101]

Correct, I think I got all that rite my issue so far is I can do this like I can see in the browser..

http://localhost:5000/webhook

But as soon I try say on the same pc its local ip and port .. it does not resolve not sure why this is ..

 

[mlapaglia]

if you go to the webhook address you should get a http 405 error if you are getting to the service correctly.

you might need to mess with your firewall settings to allow the port into your computer.

Anyway just to put a conditional statement in for when it isn't there to just assign it "N/A"??

I'm surprised you can pull car model at night. My images are pitch black except for the plates.

Gymratz found this JSON URL which returns over 90% of plates' data on year, make, model, engine, VIN, single-owner, ever been in repairs, etc.
(Just substitute 'PLATE' for a real plate, and of course 'CA' for a valid state.)

Wonder if this data could likewise be included in an overlay . . .

I thought I got a 500 response if it was working properly. Maybe I am not remembering correctly though.

I'm sorry I can't be of more help @tech101 but I'm using the Docker version on Linux and not Windows . It could very well be a Windows firewall issue preventing it. If you are getting a successful webhook test then at least you know that is working properly. Maybe disable Windows firewall totally and try again? I hate Windows which is why I run Linux for just about everything.

you'll get a 500 error from the openalpr webhook page, because it's sending it an invalid payload
you'll get a 405 trying to get to localhost:5000/webhook because it's expecting a POST, not a GET request.

Interesting, could do a comparison between what openalpr thinks the car is and what that site thinks the car is, and if they don't match up by a certain percentage put a big STOLEN CAR FAKE PLATE alert ?

Ahh ok that makes sense.

I guess you saw my log earlier that the missing parameters are still causing everything to "bomb out" as you say. I guess it wasn't as easy to fix as thought.

 

[mlapaglia]

i need to see the actual payload to be certain, i assumed the array of vehicles would be empty, i think the array is not even present when there are no vehicles.

 

[biggen]

Is it anything I can provide?

 

[mlapaglia]

if your familiar with c# pull the repo down and run it locally for testing

i need to add a debug flag to dump the webhook payloads for troubleshooting also.

 

[biggen]

Sadly I’m not much of a programmer. I’ve dabbled with Python on and off over the years but never C.

If you add the debug flag at some point I’ll run with it to capture the data you need.

 

[mlapaglia]

I have added a debug option to the configuration file to dump the webhook payloads to the logs. When you get a failure copy the JSON from the log so I can take a look.

Correct, I do get 405 when i open

http://localhost:5000/webhook

However I cannot get it to do it from internal ip:5000/webhook for some reason and I have disable windows firewall as well and nothing. not sure why..

oh, duh, since you are running on windows you have to tell it to not just listen to localhost. in your appsettings add "urls": "http://0.0.0.0:5000" to get it to listen on all interfaces. you only need to do this if you are running the windows build. docker handles this for you.

Ah, Nice I was just thinking too it was binding issue after reading thru some other stuff ..

Can't access localhost via IP address

I'm viewing a locally hosted website (using grunt serve, if that matters). I can view it via http://localhost:9000/ or http://127.0.0.1:9000/, but not via http://10.0.0.16:9000/. 10.0.0.16 is my l...

Is it suppose to look like this

  "AllowedHosts": "*",
  "Cameras": {
    "Cameras": [
      {
        "Manufacturer": "Dahua",
        "OpenAlprCameraId": ID,
        "Password": "PASS",
        "UpdateOverlayTextUrl": "http://192.168.85.35/cgi-bin/configManager.cgi?action=setConfig&VideoWidget[0].CustomTitle[1].Text=",
        "Username": "admin"
        "urls": "http://0.0.0.0:5000"
      }
    ]
  }
}

Just pulled the new container image and running it now with logging "true". I won't get the errors till tonight more than likely but I'll post them when I do.

Thanks!

Ok, I'm attaching the log file since it s real big. For some reason I'm not getting overlays any longer and I'm not sure why since nothing changed on my end. I'm getting car make/model/color stuff in the OpenALPR dashboard now that its light enough so I know everything is still working there but nothing is being overlayed on the cam.

if you turn logging off does it start working again?

 

[biggen]

Good question. I'll check
