easy_onvif 1.0.2

A pure Dart library designed primarily for command line automation of Onvif compatible devices, but can be used anywhere Dart is used.

ONVIF Client protocol Profile S (Live Streaming) Dart implementation

This is a wrapper to ONVIF protocol which allows you to get information about your NVT (network video transmitter) device, its media sources, control PTZ (pan-tilt-zoom) movements and manage presets. It will also allow you to get information about your NVR (network video recorder).

New for version 1.0.0

As of the 1.0.0 release of this package, there is a cli utility included that can be used to return data for any API call currently supported by the package. If you want to get started quicky with the cli utility run these commands in a termainal session:

pub global activate easy_onvif

onvif --help

Please see the cli documentation README.md for more detailed usage information.

Getting Started

To use this package in your code, first add the dependency to your project:

dependencies:
  ...
  easy_onvif: ^1.0.2

Usage Example

Import the easy_onvif library.

import 'package:easy_onvif/onvif.dart';

Connecting to an Onvif device

final onvif = await Onvif.connect(
 host: [hostname or ipaddress],
 username: [username],
 password: [password]);

Interacting with the device through Onvif operations

Refer to the tables below for the supported operations.

Through the deviceManagement operations you can get information about the connected device.

var deviceInfo = await onvif.deviceManagement.getDeviceInformation();

print(deviceInfo.model);

Many operations require you to supply a profileToken which can be retrieved through media operations.

var profiles = await onvif.media.getProfiles();

profiles.forEach((element) {
 print(element.name + ' ' + element.token);
});

var profileToken = profiles[0].token;

With the ptz operations you can get a list of camera presets from the connected device.

var presets = await onvif.ptz.getPresets(profileToken);

//get a specific preset
var preset = presets[11];

//print the preset values
print(
 'preset: ${preset.position.panTilt?.x}  ${preset.position.panTilt?.y}  ${preset.position.zoom?.x}');

//use the GotoPreset operation to point the camera to the given preset
await onvif.ptz.gotoPreset(profileToken, preset);

Be sure to look through the API Reference for information about the parameters required for the supported Onvif operations.
