Change ONVIF, RTSP, HTTPS, RTSPS, and service ports

Last Updated 16 days ago

ITVDesk exposes network services so a VMS/NVR can discover the virtual camera and receive video streams. Port configuration must match your network policy, firewall rules and recorder settings.

ITVDesk network settings — Network settings define service ports and interfaces used by ONVIF, RTSP and secure transports.

ITVDesk network interface list — Select the correct network interface or bind IP when the computer has multiple adapters.

ITVDesk ONVIF over HTTPS settings — Use HTTPS/TLS for protected ONVIF communication where supported by the client.

When to change ports

Another application already uses the default port.
Multiple ITVDesk services or virtual cameras need separate service bindings.
The recorder, firewall or customer network requires specific ports.
You are enabling HTTPS, RTSPS, RTSP over HTTP or secure profiles.

Recommended order

Change the port in ITVDesk.
Allow the port in Windows, Linux or macOS firewall.
Update the VMS/NVR camera configuration.
Run ITVDesk Network Camera Test before production use.

Firewall notes

ITVDesk Windows firewall rule scope: the firewall rule created for ITVDesk is bound to ITVDesk.exe. This means the rule is intended to allow ITVDesk network services only and does not open the same ports for unrelated applications.

The default ITVDesk firewall coverage is designed for the common ITVDesk service ranges:

ONVIF / Web management TCP: 7000-7099
RTSP TCP: 554, with fallback range 555-585
RTSPS TCP: 322
RTSP-over-HTTP TCP: 8080
ONVIF discovery UDP: 3702
RTP / RTCP UDP media: 22000-22127

If you use custom ports outside the default ITVDesk range, or if firewall rules are centrally managed by domain policy, allow the selected inbound TCP/UDP ports for the ITVDesk computer and keep the rule scoped to ITVDesk where possible.

Troubleshooting after changing ports

Make sure the selected port is not already used by another application or service.
If multiple ITVDesk virtual cameras are running, make sure two services are not configured to use the same static port.
Choose another port inside the recommended ITVDesk range when possible.
Check that Windows Firewall, domain firewall policy, antivirus firewall, or router rules allow the selected ITVDesk port.
If ITVDesk asks to register or allow the service port, confirm the prompt and provide administrator approval when Windows requires it.
After changing the port, update the VMS/NVR camera configuration because recorders usually keep the old port until it is changed manually.
If ONVIF discovery does not work, verify UDP 3702 and the selected ONVIF/Web management port.
If live video does not work, verify RTSP/RTSPS and the configured RTP/RTCP media transport range.

Common mistakes

Using the wrong network adapter on a multi-NIC machine.
Forgetting to update the recorder after changing ITVDesk ports.
Blocking ONVIF discovery or RTSP transport in the local firewall.
