Delphi-ONVIF

Delphi library for ONVIF IP cameras and enterprise VMS integration.

Supported platforms

Win32, Win64, Android, Linux64 (Linux64 requires Delphi Linux SDK for linking).

Architecture

Module	Purpose
ONVIF.Core	SOAP transport, WS-Security digest, fault parsing
ONVIF.Device	GetCapabilities, GetServices, device management
ONVIF.Media	Media ver10: profiles, stream/snapshot URI
ONVIF.Media2	Media ver20 / Profile T
ONVIF.PTZ	Pan/tilt/zoom control
ONVIF.Imaging	Brightness, contrast, focus
ONVIF.Events	Pull-point event subscriptions
ONVIF.Analytics	Analytics modules and rules
ONVIF.Recording	Device-side recording, search, replay
ONVIF.Client	TONVIFDevice high-level API
ONVIF.Discovery	WS-Discovery probe

VMS application layer (not in ONVIF package):

Module	Purpose
VMS.CameraRegistry	Camera list, credentials, health check
VMS.EventHub	Event aggregation per camera
VMS.RecordingEngine	Server-side RTSP recording stub
VMS.PlaybackService	Local + ONVIF replay URI resolution

Quick start

var
  Device: TONVIFDevice;
  Uri: TStreamUri;
begin
  Device := TONVIFDevice.Create;
  try
    if Device.Connect('http://192.168.1.100/onvif/device_service', 'admin', 'pass') then
    begin
      Uri := Device.GetStreamUri(Device.Profiles[0].token, 'RTP-Unicast', 'RTSP');
      // Use Uri.Uri with your RTSP player
    end;
  finally
    Device.Free;
  end;
end;

ONVIF operations coverage

See tests/fixtures for sample SOAP responses used in parser tests.

Service	Key operations
Device	GetDeviceInformation, GetCapabilities, GetServices, GetSystemDateAndTime, GetUsers, GetNetworkInterfaces, SystemReboot
Media ver10	GetProfiles, GetStreamUri, GetSnapshotUri, GetVideoSources, Multicast streaming
Media2	GetProfiles, GetStreamUri, GetSnapshotUri
PTZ	ContinuousMove, Stop, GetStatus, GetPresets, GotoPreset
Imaging	Get/SetImagingSettings, GetOptions, Move, Stop
Events	CreatePullPointSubscription, PullMessages, Renew, Unsubscribe
Analytics	Get/Modify AnalyticsModules and Rules
Recording	GetRecordings, FindRecordings (+ GetRecordingSearchResults, EndSearch), GetReplayUri

Migration from legacy API

Replace GetONVIFAddr(XAddr, atMedia) with:

Device.Connect(XAddr, User, Pass);
MediaUrl := Device.MediaEndpoint;

Legacy functions in unit ONVIF remain available for backward compatibility.
