# ONVIF cameras

Video Capture SDK .Net VideoCaptureCoreX VideoCaptureCore

ONVIF is a standard for physical IP cameras. Many cameras and NVRs support the ONVIF protocol. It is a good idea if you need to support many cameras.

# How to enumerate ONVIF cameras

Enumerate ONVIF sources and add them to a combo box.

var uris = await VideoCapture1.IP_Camera_ONVIF_ListSourcesAsync(null, null);
foreach (var uri in uris)
{
    cbIPCameraURL.Items.Add(uri);
}

var uris = await DeviceEnumerator.Shared.ONVIF_ListSourcesAsync(TimeSpan.FromSeconds(2), null);
foreach (var uri in uris)
{
    cbIPCameraURL.Items.Add(uri);
}

# How can I get camera capabilities and information?

Create a new camera object and connect it to the camera:

var onvifControl = new ONVIFControl();
var result = await onvifControl.ConnectAsync("http://192.168.1.2/onvif/device_service", "username", "password");
if (!result)
{
    onvifControl = null;
    Debug.WriteLine("Unable to connect to the ONVIF camera.");
    return;
}

var onvifDevice = new ONVIFDevice();
var result = await onvifDevice.ConnectAsync("http://192.168.1.2/onvif/device_service", "username", "password");
if (!result)
{
    onvifControl = null;
    Debug.WriteLine("Unable to connect to the ONVIF camera.");
    return;
}

Get camera information:

var deviceInfo = await onvifControl.GetDeviceInformationAsync();
if (deviceInfo != null)
{
    Debug.WriteLine($"Model {deviceInfo.Model}, Firmware {deviceInfo.Firmware}");
}

var deviceInfo = onvifDevice.GetDeviceInformation();
if (deviceInfo != null)
{
    Debug.WriteLine($"Model {deviceInfo.Model}, Firmware {deviceInfo.Firmware}");
}

Get profiles:

var profiles = await onvifControl.GetProfilesAsync();
foreach (var profile in profiles)
{
    Debug.WriteLine($"{profile.Name}");
}

var profiles = await onvifDevice.Media.GetProfilesAsync();
if (profiles != null)
{
    foreach (var profile in profiles)
    {
        Debug.WriteLine($"Profile {profile.Name}, {profile.token}");
    }
}

Get video RTSP URL to connect:

// Get URL using the profile index
var url = await onvifControl.GetVideoURLAsync(0);

// Get endpoints
var endPoints = onvifDevice.MediaEndpoints;
if (endPoints.Length > 0)
{
   // Get URL using the profile index
   var rtspUri = endPoints[0].Uri.Uri;
   if (rtspUri != null)
   {
       uri = new Uri(rtspUri);
   }
}

Retrieve PTZ ranges (optional):

var ranges = await onvifControl.PTZ_GetRangesAsync();

var ranges = onvifDevice.PTZ.GetRanges();
