Integrate D4200-VE IP speaker/siren with Geutebruck custom button

[AaronV155]

Hi,

I have gone through your VAPIX library and was able to find a json script that worked. I also found the same script inside the speaker itself. Working script is:
{
"apiVersion": "1.0",
"context": "my context",
"method": "start",
"params": {
"profile": "AHAlarm"
}
}

If I send this in Postman the siren works straight away.

The problem we are having is that Geutebruck doesn't except HTTP posts in json format, its looking to send it in a 1 line URL.

Are you able to take the above json and turn it into a 1 line URL post that will be accepted by the speaker?

Answers to your questions will most often come from the community, from developers like yourself. You will, from time to time, find that Axis employees answers some of the questions, but this is not a guarantee. Think of the discussion forum as a complement to other support channels, not a replacement to any of them.

If your question remains unanswered for a period of time, please revisit it to see whether it can be improved by following the guidelines listed in Axis support guidelines.

[AaronV155]

Yeah well thats how it works in Postman, the json being sent as the body of the http request.

For whatever reason Geutebruck does not accept json as the body of the http post, which i find really strange

I have both axis and guetebruck engineers working on a solution (if there is one)

I will post if we do end up getting an answer

[apljungquist]

I don't think so. The JSON is typically sent in the body of a HTTP POST request, which is separate from the URL ¹. One workaround I can think of is using a custom ACAP app that uses Web server via Reverse Proxy and VAPIX access for ACAP applications.

Hi @AaronV155 ,
I suggest something as middle ware may be an ACAP or Raspberry Pi 5 server/ ESP32-C6 server which receive the GET call and pass the POST call 😄

Gravio is made of Nodes
Node-RED Flows

[AaronV155]

Iv never done anything with ACAP, but do you mean having like a proxy server that essentially translates the message between the 2 systems?

[vivekatoffice]

Try combining the vapix example with web-server-using-fastcgi / web-server to create an ACAP which receive the GET call and map it with POST VAPIX APIs.

[apljungquist]

I thought this sounded like a fun app to write... so I did. I don't have a camera at hand this morning, so I haven't had a chance to test it, but if you are interested in using it then I will test it for sure.

[AaronV155]

Oh wow, you made an app that could potentially do what i need?

I would be happy to test it, probably wont be able to til next week unfortunately.

[apljungquist]

No rush, happy anytime I can build something that is useful to someone. Just let me know in advance if you want me to build the eap files for you :)

[apljungquist]

@AaronV155 did you have a chance to test the app and/or have you found another solution for your problem?

[vivekatoffice]

Hi @AaronV155 ,

I have tested the ACAP from @apljungquist successfully using AXIS D4100-E Network Strobe Siren (AXIS OS version 11.11.160) (armv7hf) 😄

I am attaching the build ACAPs here for you so it will be easy for your testing.

Thank you @apljungquist for the ACAP again 😄 . This can be used in various use cases. Now Geutebrueck VMS can send the GET request with Digest Auth via your ACAP😉

[AaronV155]

Hi guys,

Sorry for the late reply, i have been on other projects

I had a look at it, but honestly its a bit above my knowledge base. Im not much of a code programmer lol.

The main issue is Geutebruck seems very limited in what it can actually post as a http command.

I tried a bunch on curl commands also, quite similar to the ones you guys designed. I even tried the one you had that worked (changing fields accordingly) and it didnt work.

I tasked both Geutebruck and Axis tech supports with getting me a soultion. Neither have gotten back to me.

Instead i have opted to go for a solution i know will work 100% and thats an axis camera talking directly to the speaker.

Hopefully ill get out there sometime next week to finish this job off.

I honestly didnt expect much from this forum but you guys were fantastic.

Will use again in the future

Thank you all for your efforts 😀

What version of Geutebruck software do you use (4.x, 5.x, 6.x, 7.x)?
Do you use the AXIS or ONVIF plugin?

The simplest way Geutebruck->Axis virtual I/O->Axis Event.

If you want more advanced integration contacts with me directly.

[AaronV155]

Latest version, brand new NVRS and gsim server

[rocky-ji]

Axis device has 32 or 64 virtual input port, you can control to send http get to camera to control its status, change port to different number as you needed:
http://192.168.1.203/axis-cgi/virtualinput/activate.cgi?schemaversion=1&port=1
http://192.168.1.203/axis-cgi/virtualinput/deactivate.cgi?schemaversion=1&port=1

in Axis device event, you can setup event to judge that virtual input port status, and then send out http post to control it.

I think this should work for your case. No extra ACAP needed. Just setup

[rocky-ji]

port number should be the same, in my snapshot, i select port 2, so the command should also send to port 2:
To activate virtual port 2:
http://192.168.1.203/axis-cgi/virtualinput/activate.cgi?schemaversion=1&port=2

To deactivate virtual port 2:
http://192.168.1.203/axis-cgi/virtualinput/deactivate.cgi?schemaversion=1&port=2
