node-onvif

The node-onvif is a Node.js module which allows you to communicate with the network camera which supports the ONVIF specifications.

The ONVIF (Open Network Video Interface) is an open industry forum promoting and developing global standards for interfaces of IP-based physical security products such as network cameras. The ONVIF specifications are available in their web site.

Recently, most of network cameras for business support the ONVIF standard. Furthermore, some network cameras for home support it though the implementation is partial. The node-onvif allows you to control network cameras which implement the ONVIF standard.

The node-onvif provides you with the APIs as follows:

  • Discovery the ONVIF network cameras
  • Access some services supported by the ONVIF network cameras as follows:
    • Device Management Service
    • Media Service
    • PTZ Service

Besides, the node-onvif provides you with simple APIs that allow you to control ONVIF network cameras easily even if you are not familiar with the ONVIF specifications.

Dependencies

Installation

$ npm install xml2js
$ npm install html
$ npm install node-onvif

Sample Application

This package includes a sample application "ONVIF Network Camera Manager". You can try this module with your PTZ ONVIF network camera easily.

ONVIF Network Camera Manager


Table of Contents


This section shows how to discover ONVIF network cameras, how to get the device information, and how to control the PTZ of the device.

This sample code shows how to discover ONVIF network cameras.

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

console.log('Start the discovery process.');
// Find the ONVIF network cameras
onvif.startDiscovery((info) => {
  // Show the device name and the URL of the end point
  console.log('- ' + info.urn);
  console.log('  - ' + info.name);
  console.log('  - ' + info.xaddrs[0]);
});

// Stop the discovery process in 3 seconds
setTimeout(() => {
  onvif.stopDiscovery(() => {
    console.log('Stopped the discovery process.');
    process.exit();
  });
}, 3000);

The code above will output the result like this:

Start the discovery process.
- urn:uuid:4d454930-0000-1000-8000-bcc34217e292
  - Panasonic BB-SC384B
  - http://192.168.10.17/onvif/device_service
- urn:uuid:812b12f7-45a0-11b5-8404-c056e3a2e020
  - Vstarcam
  - http://192.168.10.14:10080/onvif/device_service
- urn:uuid:6b2be733-6ad1-4467-8bd0-747bd8efd206
  - Avantgarde-Test
  - http://192.168.10.22:36000/onvif/device_service
Stopped the discovery process.

The most important information for controlling the device is the URL of the end point of the device. You can get the URL from the code info.xaddrs[0] above.

In order to control the ONVIF network camera, you have to create an OnfivDevice object for the device. This sample code shows how to create an OnvifDevice object and get the detailed information of the device.

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

// Create an OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '123456'
});

// Initialize the OnvifDevice object
device.init((error) => {
  if(error) {
    console.log('[ERROR] ' + error.message);
  } else {
    // Get the detailed device information
    var device_info = device.getInformation();
    // Show the result
    console.log(JSON.stringify(device_info, null, '  '));
  }
});

The code above will output the result like this:

{
  "Manufacturer": "Vstarcam",
  "Model": "Hi3518eV100",
  "FirmwareVersion": "2.4",
  "SerialNumber": "3056894",
  "HardwareId": "1.0"
}

This sample code shows how to get the UDP stream URL.

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

// Create an OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '123456'
});

// Initialize the OnvifDevice object
device.init((error) => {
  if(error) {
    console.log('[ERROR] ' + error.message);
  } else {
    // Get the UDP stream URL
    var url = device.getUdpStreamUrl();
    console.log(url);
  }
});

The code above will output the result like this:

rtsp://192.168.10.14:10554/tcp/av0_0

This sample code shows how to get the data of the snapshot and save it to a file.

var onvif = require('node-onvif');
var fs = require('fs');

// Create an OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '123456'
});

// Initialize the OnvifDevice object
device.init((error) => {
  if(error) {
    console.log('[ERROR] ' + error.message);
    return;
  }
  // Get the data of the snapshot
  console.log('fetching the data of the snapshot...');
  device.fetchSnapshot((error, res) => {
    if(error) {
      console.log(error.message);
      return;
    }
    // Save the data to a file
    fs.writeFile('snapshot.jpg', res.body, function (error) {
      if(error) {
        console.log(error.message);
      } else {
        console.log('Done!');
      }
    });
  });
});

The code above will output the result like this:

fetching the data of the snapshot...
Done!

You will find a JPEG file named snapshot.jpg in the current directory.

This sample code shows how to pan, tilt, and zoom the ONVIF network camera.

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

// Create an OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '123456'
});

// Initialize the OnvifDevice object
device.init((error) => {
  if(error) {
    console.log('[ERROR] ' + error.message);
    return;
  }
  // Create the parameters
  var params = {
    'speed': {
      x: 1.0, // Speed of pan (in the range of 0 to 1.0)
      y: 0.0, // Speed of tilt (in the range of 0 to 1.0)
      z: 0.0  // Speed of zoom (in the range of 0 to 1.0)
    },
    'timeout': 1 // seconds
  };
  // Move the camera
  device.ptzMove(params, (error) => {
    if(error) {
      console.log(error.message);
    } else {
      console.log('Done!');
    }
  });
});

If this code has been successfully finished, you could find that the camera turns to the right for a second at the highest speed.


In order to use the node-onvif module, you have to load the node-onvif module as follows:

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

The variable onvif in the code above is the Onvif object.

This section describes the methods implemented in the Onvif object.

This method starts the discovery process and tries to find the ONVIF network camera devices. Whenever an ONVIF network camera device is found, the callback function specified to the 1st argument will be called.

When a device is found, the callback will be passed a hash object as the 1st argument. The properties set to the hash object are as follows:

Property Type Description
urn String The URN (Uniform Resource Name) assigned to the device (e.g., "urn:uuid:6b2be733-6ad1-4467-8bd0-747bd8efd206")
name String The product name of the device (e.g., "Panasonic BB-SC384B").
hardware String The description of the hardware of the device (e.g., "BB-SC384B").
location String The physical location of the device (e.g., "China", "shenzhen", "office").
types Array The list of types supported by the device (e.g., "dn:NetworkVideoTransmitter", "tds:Device"). Basically, this module is for "dn:NetworkVideoTransmitter".
xaddrs Array The list of URLs of the end points (e.g., "http://192.168.10.17/onvif/device_service", "http://[2408:12:2e20:d000:bec3:42ff:fe17:e292]/onvif/device_service").
scopes Array The list of scopes set to the device (e.g., "onvif://www.onvif.org/Profile/Streaming", "onvif://www.onvif.org/location/office").

The sample code below shows the structure of the hash object representing the found device.

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

// Find the ONVIF network cameras
onvif.startDiscovery((info) => {
  // Show the information of the found device
  console.log(JSON.stringify(info, null, '  '));
});

The code above will output the result like this:

{
  "urn": "urn:uuid:4d454930-0000-1000-8000-bcc34217e292",
  "name": "Panasonic BB-SC384B",
  "hardware": "BB-SC384B",
  "location": "office",
  "types": [
    "dn:NetworkVideoTransmitter",
    "tds:Device"
  ],
  "xaddrs": [
    "http://192.168.10.17/onvif/device_service",
    "http://[2408:12:2e20:d000:bec3:42ff:fe17:e292]/onvif/device_service"
  ],
  "scopes": [
    "onvif://www.onvif.org/Profile/Streaming",
    "onvif://www.onvif.org/hardware/BB-SC384B",
    "onvif://www.onvif.org/location/office",
    "onvif://www.onvif.org/name/Panasonic_BB-SC384B",
    ""
  ]
}

This method stops the discovery process asynchronously. If you want to do something waiting for stopping the discovery process successfully, you can pass a callback function to this method as the 1st argument.

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

// Start the discovery process
onvif.startDiscovery((info) => {
  // Do something
});

// Stop the discovery process in 3 seconds
setTimeout(() => {
  onvif.stopDiscovery(() => {
    // If you want to do something after stopping
    // the discovery process successfully, write
    // codes here.
  });
}, 3000);

If you don't need to do anything after the discovery process has been terminated successfully, you can do this:

onvif.stopDiscovery();

The OnvifDevice object represents an ONVIF network camera device. You can control the ONVIF network camera through this object.

In order to control an ONVIF network camera, you have to create an OnvifDevice object from the OnvifDevice constructor by yourself as follows:

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

// Create an OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '123456'
});

The variable device represents an OnvifDevice object in the code above. The OnvifDevice constructor requires a hash object consisting of some properties as follows:

Property Type Required Description
xaddr String required URL of the end point of the targeted device.
user String optional User name for the user authentication.
pass String optional Password for the user authentication.

If you know the value of the xaddr property (the URL of the end point of the targeted device) in advance, you don't need to run the discover process(i.e., you don't need to call the startDiscovery() method).

The OnvifDevice object provides some properties as follows:

Property Type Description
services Object
       | `device` | Object | [`OnvifServiceDevice`](#OnvifServiceDevice-object) object
       | `media`  | Object | [`OnvifServiceMedia`](#OnvifServiceMedia-object) object
       | `ptz`    | Object | [`OnvifServicePtz`](#OnvifServicePtz-object) object

See the section "ONVIF commands" for details.

This method Initializes the OnvifDevice object. This method must be called before you control the targeted device. Actually, this method retrieves several information essential to control the device from the device.

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

// Create an OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '888888'
});

// Initialize the OnvifDevice object
device.init((error) => {
  if(error) {
    console.log('[ERROR] ' + error.message);
  } else {
    console.log('The OnvifDevice object has been initialized successfully.')
    // Do something.
  }
});

This method is executed asynchronously. The process of this method takes a little time to be completed because this method sends several commands to the targeted device and waits for the all relevant responses. Though the callback function is optional, you have to wait for the completion of this method to control the device. Therefore, the code below will doesn't work well:

// Never do this
device.init();
var info = device.getInformation();
...

Instead, do this:

device.init((error) => {
  if(!error) {
    var info = device.getInformation();
    ...
  }
});

This method returns a hash object consisting of several device information as follow:

Property Type Description
Manufacturer String The manufactor of the device.
Model String The device model.
FirmwareVersion String The firmware version in the device.
SerialNumber String The serial number of the device.
HardwareId String The hardware ID of the device.
var info = device.getInformation();
console.log(JSON.stringify(info, null, '  '));

The code above will output the result like this:

{
  "Manufacturer": "Vstarcam",
  "Model": "Hi3518eV100",
  "FirmwareVersion": "2.4",
  "SerialNumber": "3056894",
  "HardwareId": "1.0"
}

The ONVIF network cameras have several profiles by default. The profile is a set of configuration values such as the resolution of the video encoder, the URL of the snapshot, the URL of the video stream, the range of PTZ, and so on.

The OnvifDevice object is sure to select one of them and each method implemented in the OnvifDevice object is executed using the selected profile. By default, the OnvifDevice object selects the profile found first in the initialization process.

This method returns a hash object containing the information of the profile currently selected by the OnvifDevice object.

var profile = device.getCurrentProfile();
console.log(JSON.stringify(profile, null, '  '));

The code above will output the result like this:

{
  "token": "PROFILE_000",
  "name": "PROFILE_000",
  "snapshot": "http://192.168.10.14:81/snapshot.cgi",
  "stream": {

        "height": 720,
        "x": 0,
        "y": 0
      }
    },
    "encoder": {
      "token": "V_ENC_000",
      "name": "V_ENC_000",
      "resolution": {

      },
      "quality": 4,

      "encoding": "G711"
    }
  },
  "ptz": {
    "range": {
      "x": {
        "min": -1,
        "max": 1
      },
      "y": {
        "min": -1,
        "max": 1
      },
      "z": {
        "min": 0,
        "max": 1
      }
    }
  }
}

This method returns a list of the profiles set to the device as an Array object. Each element in the Array object is a hash object whose structure is as same as the hash object which can be retrieved by the getCurrentProfile() method.

See the section "changeProfile() method" for details.

This method changes the current profile to the profile corresponding to the index specified as the 1st argument, then returns a hash object representing the newly selected profile. The index is the position in the profile list which can be obtained through the getProfileList() method, which is in the range of 0 to the length of the list minus 1.

The sample code below shows how to change the current profile to the profile whose video resolution is the smallest:

// Get the current profile
var profile = device.getCurrentProfile();
// Show the video resolution of the current profile
var reso = profile['video']['encoder']['resolution'];
console.log('- Before: ' + reso['width'] + ' x ' + reso['height']);

// Get a list of the profiles set in the device
var profile_list = device.getProfileList();

// Find the profile whose video resolution is the smallest
var min_square = 4000 * 2000;
var min_index = 0;
for(var i=0; i<profile_list.length; i++) {
  var resolution = profile_list[i]['video']['encoder']['resolution'];
  var square = resolution['width'] * resolution['height'];
  if(square < min_square) {
    min_square = square;
    min_index = i;
  }
}

// Change the current profile
profile = device.changeProfile(min_index);

// Show the video resolution
reso = profile['video']['encoder']['resolution'];
console.log('- After: ' + reso['width'] + ' x ' + reso['height']);

This sample code will output the result like this:

- Before: 1280 x 720
- After: 320 x 180

This method returns the UDP Stream URL. Though the URL can be obtained from the result of the getCurrentProfile() method as well, this method makes that easy.

var url = device.getUdpStreamUrl();
console.log(url);

The code above will output the result like this:

rtsp://192.168.10.14:10554/tcp/av0_0

This method fetches a snapshot captured by the camera at the time. The snapshot is obtained as a Buffer object representing the image data of the snapshot.

As the snapshot is obtained asynchronously, a callback function has to be passed to this method as the 1st argument.

If an error occurs, an Error object is passed to the callback function as the 1st argument. If the snapshot is captured successfully, a hash object is passed to the callback function as the 2nd argument. The hash object consists of some properties as follows:

Property Type Description
headers Object headers object representing the HTTP response header. This object is of the http module of Node.js.
body Object Buffer object representing the image data of the snapshot.

The code blow shows how to get the snapshot and save it as an image file:

device.fetchSnapshot((error, res) => {
  if(error) {
    console.log(error.message);
    return;
  }
  // Determine the file extention
  var ext = 'bin';
  var mime_pair = res.headers['content-type'].split('/');
  if(mime_pair[0] === 'image') {
    ext = mime_pair[1];
  }
  // Save the data to a file
  var fname = 'snapshot.' + ext;
  fs.writeFile(fname, res.body, function (error) {
    if(error) {
      console.log(error.message);
    } else {
      console.log('Done!');
    }
  });
});

This method pans, tilts, zooms the camera if the ONVIF network camera supports the PTZ service. 2 arguments have to be passed to this method: the 1st argument is a hash object, the 2nd argument is a callback function.

The structure of the hash object to be passed as the 1st argument is as follows:

Property Type Required Description
speed Object required
      | `x` | Float   | required | Speed of pan in the range of -1.0 to 1.0.
      | `y` | Float   | required | Speed of tilt in the range of -1.0 to 1.0.
      | `z` | Float   | required | Speed of zoom in the range of -1.0 to 1.0.

timeout | | Integer | optional | Timeout in seconds (Default: 1)

The speed.x represents the speed of horizontal movement of the camera. If the value of the speed.x is positive, the camera will turn to the right. If the value is negative, the camera will turn to the left. If the value is zero, the camera won't move in a horizontal direction.

The speed.y represents the speed of vertical movement of the camera. If the value of the speed.y is positive, the camera will turn to the top. If the value is negative, the camera will turn to the bottom. If the value is zero, the camera won't move in a vertical direction.

The speed.z represents the speed of the zoom of the camera. If the value of the speed.z is positive, the camera will zoom in. If the value is negative, the camera will zoom out. if the value is zero, the camera won't zoom.

// Create the parameters
var params = {
  'speed': {
    x: 1.0, // Speed of pan (in the range of -1.0 to 1.0)
    y: 0.0, // Speed of tilt (in the range of -1.0 to 1.0)
    z: 0.0  // Speed of zoom (in the range of -1.0 to 1.0)
  },
  'timeout': 1 // seconds
};

// Move the camera
device.ptzMove(params, (error) => {
  if(error) {
    console.log(error.message);
  } else {
    console.log('Done!');
  }
});

This method stops the movement of the camera caused by the ptzMove() method.

// Create the parameters
var params = {
  'speed': {x: 0.5, y: 0.0, z: 0.0},
  'timeout': 60 // seconds
};

// Supposed to move the camera for 60 seconds
device.ptzMove(params, (error) => {
  if(error) {
    console.log(error.message);
  } else {
    console.log('Succeeded to move.');
  }
});

// Stop to the PTZ in 2 seconds
setTimeout(() => {
  device.ptzStop((error) => {
    if(error) {
      console.log(error.message);
    } else {
      console.log('Succeeded to stop.');
    }
  })
}, 2000);

Note that the all sections below are for those who are familiar with the ONVIF specifications.

The ONVIF specifications define a lot of SOAP-based commands. This module implements part of the commands. Actually, most of the methods described in the previous sections are implemented using the methods representing the commands described the sections below.

The methods for the ONVIF commands are exposed in the OnvifServiceDevice object, the OnvifServiceMedia object, and OnvifServicePtz object, which are available from the OnvifDevice.device property, the OnvifDevice.media property, and the OnvifDevice.ptz property, respectively.

For example, if you want to call the GotoHomePosition command, you can use the gotoHomePosition method implemented in the OnvifServicePtz object like this:

// Create a OnvifDevice object
var device = new onvif.OnvifDevice({
  xaddr: 'http://192.168.10.14:10080/onvif/device_service',
  user : 'admin',
  pass : '123456'
});

// Initialize the OnvifDevice object
device.init((error) => {
  if(error) {
    console.log('[ERROR] ' + error.message);
    return;
  }
  // The OnvifServicePtz object
  var ptz = device.services.ptz;
  if(ptz) {
    // The parameters for the gotoHomePosition() method
    var profile = device.getCurrentProfile();
    var params = {
      'ProfileToken': profile['token'],
      'Speed'       : 1
    };
    // Send the GotoHomePosition command using the gotoHomePosition() method
    ptz.gotoHomePosition(params, (error, result) => {
      if(error) {
        console.log('[ERROR] ' + error.message);
      } else {
        console.log(JSON.stringify(result.data, null, '  '));
      }
    });
  } else {
    console.log('[ERROR] Your ONVIF network camera does not support the PTZ service.');
  }
});

The code above will output the result like this:

{
  "GotoHomePositionResponse": {
    "$": {
      "xmlns": "http://www.onvif.org/ver20/ptz/wsdl"
    }
  }
}

Actually, the response from the targeted ONVIF network camera is SOAP. This module provides some representations of the response. the variable result in the code above consists of some properties as follows:

Property Type Description
soap String Raw SOAP response
formatted String Formatted SOAP response in order to be human readable
converted Object JavaScript object converted from SOAP response by xml2js module
data Object JavaScript object converted from the data in the <Body> element in the SOAP response

In most cases, only data property would be enough. If you need to evaluate the response in more detail, you can use the preferable property other than the data property.

This method sends a SetPreset command. The 1st argument params must be a hash object consisting of the properties as follows:

Property Type Required Description
ProfileToken String required a token of the profile
PresetToken String optional a token of the preset
PresetName String optional a name of the preset
var params = {
  'ProfileToken': '2_def_profile6',
  'PresetToken' : '12',
  'PresetName'  : 'PresetTest1'
};

device.services.ptz.setPreset(params, (error, result) => {
  console.log(JSON.stringify(result['data'], null, '  '));
});

This method sends a GetPresets command. The 1st argument params must be a hash object consisting of the properties as follows:
