PTZ control (rotation control)

[jimdaft]

I m starting to work on how the camera rotation is controlled. Any ideas are welcome.

Good job I played a bit with this myself https://github.com/futomi/node-onvif It has also PTZ controls

[jimdaft]

This cam does not support Onvif

[diekaines]

Maybe my bad but i tested that script and i was able to get the information from camera.

It does support onvif PTZ. I've tested it using various Android apps.

[diekaines]

This is the results using that nodejs library. Whats strange though is that the PTZ min/max are null but like @ant-thomas said it works with many PTZ apps for android and also the usual ONVIF DEVICE MANAGER

Playing a bit with ONVIF DEVICE MANAGER and doing a bit of wireshark capture i was able to replicate the PTZ by sending a POST ( via POSTMAN ) to the camera and it moved https://prnt.sc/hjf44a

Here the code for the nodejs library i mentioned above

I had to change the XADDR to the one you see on the code below and it worked

const onvif = require('node-onvif');

// NOTICE THE URL which is different from the examples on https://github.com/futomi/node-onvif
let device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.66.101/onvif/PTZ',
  user : 'admin',
  pass : '12345'
});

device.init().then(() => {
  // Move the camera
  return device.ptzMove({
    'speed': {
      x: 1.0, 
      y: 0.0,
      z: 0.0
    },
    'timeout': 1 // seconds
  });
}).then(() => {
  console.log('Done!');
}).catch((error) => {
  console.error(error);
});

Good Job. I was doing same thing yesterday and I confirm that with ONVIF DEVICE MANAGE it works (onvifer app didn't recognize it as onvif device).

With IP Cam for Android get the picture very nice, but the PTZ dosent work.

:(

@DrakoZ900

Make sure your connected to ONVIF port 80. If you connect directly to the stream via rtsp 554 you wont get PTZ control.

Using this project https://github.com/futomi/node-onvif I have managed to run PTZ using onvif :) Sample project written very clearly. Only case is server application couldn't get a snapshot from the camera. Whenever I disable "this.fetchSnapshotCallback(data);" function from the client (sample/html/onvif.js), you can move the camera using keyboard direction buttons :) Only thing is library can't get a snapshot from camera. Right now I'm working on figuring out why server can't get a snapshot from the live stream. Somehow cameras are not giving proper response and client-server socket connection dropping :(
