  Hi @...,

  Please check out server API in the WebAdmin:

  1. Click onm the For Developers tab and select API Testing Tool (new).
  2. Navigate to ptz.
  3. Enter the cameraId of the applicable PTZ camera.
  4. Select the proper command at the command enum.
  5. Call the GetPresetsPtzCommand to get the list of available presets and select the one you want to trigger.
  6. Call the ActivatePresetPtzCommand + presetId + speed parameters to move to the selected preset position.

  

  The URL would look like something like this:

  https://localhost:7001/api/ptz?cameraId=<cameraId>&command=ActivatePresetPtzCommand&presetId=<presetId>&speed=1

  Hi Norman Graafsma,

  I have tried to activate the preset PTZ through the API, and API looks to return "successfully done", however it didn't work (not move to preset position). May I know any possibilities why it did not work?

  Camera: Panasonic WV-S6110

  // get a list of presets.
  curl 'http://admin:Demo1234@192.168.1.254:7011/api/ptz?cameraId=2bc31e89-d842-6f68-5da5-3b16b25fa00e&command=GetPresetsPtzCommand'
  {
    "error": "0",
    "errorString": "",
    "reply": [
      {
        "id": "{3ceb4385-9eb6-4a1a-8f91-88f365636814}",
        "name": "MTG"
      },
      {
        "id": "{7f721fc2-e98a-4a20-90b1-4f984b5c3d40}",
        "name": "Top"
      },
      {
        "id": "{10a81ba7-945d-4561-ad43-2f6b0154869e}",
        "name": "Home"
      }
    ]
  }
  // activate preset PTZ.
  curl 'http://admin:Demo1234@localhost:7011/api/ptz?cameraId=2bc31e89-d842-6f68-5da5-3b16b25fa00e&command=ActivatePresetPtzCommand&presetId=7f721fc2-e98a-4a20-90b1-4f984b5c3d40&speed=1'
  {"error":"0","errorString":"","reply":null} // looks OK.

  Hi @...,

  Can you paste the URL in the web browser and capture this event in Wireshark and share the Wireshark capture file with us?

  Thank you for your support. Okay, let capture packets between browser and Nx Witness Media Server. Or do you need the captured packets between Nx Witness Media Server and IP Camera?

  Hi @...,

  Browser and server, since the browser sends the command to the server.
  We would expect an HTTP 200 OK reply.

  Besides that, we would like a capture between server and the applicable PTZ camera, to check the response there.

  Also, it might be useful if we can have the reply to the following API call:

  http://<serverIpAddress>:7001/ec2/getCamerasEx

  Thanks a lot. I have captured packets between browser and server, an authentication error and an internal server error happened. Could you give me any further instruction?

  

  (Pasted URL to browser)

  http://admin:Demo1234@192.168.1.254:7011/api/ptz?cameraId=2bc31e89-d842-6f68-5da5-3b16b25fa00e&command=ActivatePresetPtzCommand&presetId=7f721fc2-e98a-4a20-90b1-4f984b5c3d40&speed=1

  If you need entire captured packets, please let me know.

  Hello Keisuke Sawada,

  I'm sorry, I have not read attentively enough. No need in HTTPS in this case.

  What is the build number of the server, you are using?

  Could you please redo the test with capturing packets and share this network dump with us?

  Hi Andrey,

  No problem. I have captured packets btw client and server as following. At 39 & 41, successfully got a list of preset PTZ, but at 78 & 79, internal error occurred at activating PTZ. Could you take a look at this?

  Hello Andrey Terentyev,

  May I know current progress of handling this query? Now our customer is evaluating Nx Witness how to activate preset PTZ with an external application. If you need further information, please let me know.

  A support ticket had been crated to investigate  behavior or the camera in question.

  Here is the result.

  Thank you for handling my request.
  Unfortunately, the camera (Panasonic) caused the issue has already been returned back to a vendor. So I cannot set up the investigation environment for you.
  On the other hand, the PTZ activation through API of another camera (Axis) worked very fine. Now we have updated current situation to the customer and waiting for the reply.
  If we need to have further investigation of the Panasonic camera, then let me request you to have detail investigation again.
