Frequently Asked Question

After ITVDesk is installed, activated, and configured with a video source, first verify the stream directly inside ITVDesk. After the internal test is successful, add ITVDesk to your VMS/NVR as a virtual ONVIF IP camera.

1. Confirm ITVDesk is running

• Start ITVDesk on the computer that will act as the virtual IP camera.
• Confirm that the selected source is active and the stream is running.
• Check the computer IP address and the network interface used by ITVDesk.

2. Use Preview & Test before adding ITVDesk to a VMS/NVR

ITVDesk includes built-in test tools for checking whether the virtual IP camera is ready for a recorder or VMS system.

• Open the ITVDesk front application and use Preview & Test.
• Check the ONVIF and RTSP service indicators.
• Use Test Stream to verify that ITVDesk can serve the video stream locally.
• Use Network Camera Test (NVR Readiness) to verify port access, bind IP, authentication, and stream profile readiness.
• If the internal test fails, fix ITVDesk source, service, firewall, or port configuration before adding the device to a VMS/NVR.

Detailed documentation: Preview & Test and Network Camera Test (NVR Readiness).

3. Check ONVIF and stream settings

• Verify that ONVIF service is enabled.
• Check the ONVIF HTTP/HTTPS port configured in ITVDesk.
• Check RTSP/RTSPS/SRT stream settings if your VMS/NVR will use direct stream URLs.
• Confirm username/password if authentication is enabled.
• Allow the required ports in Windows Firewall, Linux firewall, macOS firewall, or network security equipment.

4. Add the device in your VMS/NVR

• Use ONVIF discovery if your VMS/NVR supports automatic discovery.
• If discovery does not find ITVDesk, add it manually using the ITVDesk computer IP address, ONVIF port, and credentials.
• Select ONVIF or a compatible generic camera profile when required.
• For systems that prefer direct streams, use the RTSP/RTSPS/SRT URL generated by ITVDesk.

5. Test live view and recording in the VMS/NVR

• Open live view in the VMS/NVR.
• Verify video resolution, frame rate, codec, audio, and stream stability.
• Start recording and confirm playback works as expected.
• Test PTZ desktop interaction, two-way audio, OSD/subtitles, events, or secure transport if those features are required.

6. If discovery or video does not work

• First run ITVDesk Preview & Test and Network Camera Test.
• Confirm ITVDesk and the VMS/NVR are on reachable network segments.
• Check local firewall rules and port conflicts.
• Verify ONVIF credentials and authentication mode.
• Try manual add using the ITVDesk IP address and ONVIF port.
• Check codec support in the VMS/NVR and lower resolution/frame rate for testing.
