Frequently Asked Question
Use this article to change the ONVIF port: the port that your NVR/VMS uses to find and control DeskCamera.
By default, DeskCamera uses ONVIF port 8090 for the first camera. DeskCamera picks ONVIF ports from 8090–8110. It keeps the same ports after restarts, updates and user switching. Usually it is best to leave ONVIF port set to Auto.
For the full port list and firewall details, see Ports Used by DeskCamera and Firewall Rules.
Multiple Channels mode and Multiple Cameras mode
A Fixed ONVIF port works only in Multiple channels mode. In Multiple cameras mode, DeskCamera picks the ports itself, even if Fixed is selected.
Set a fixed ONVIF port
Click Stop.
Click OPTIONS > General.
Under PORTS, next to ONVIF port, click Fixed.
Type the port number in the box next to Fixed.
When you click outside the box, DeskCamera can ask to reserve the port. Click Yes.
If Windows asks for permission, click Yes.
Click << BACK, then click Start.
After the camera starts, check the Started Cameras list and use the displayed ONVIF address when adding DeskCamera to an NVR/VMS.
If the port number changed, change it in the NVR/VMS too.
Multi-user mode notes
If several Windows users may run DeskCamera at the same time, avoid using the same fixed ONVIF port for more than one user. Use Auto, or give each user a different Fixed port.
Firewall notes
If you use a fixed ONVIF port outside the default range, allow inbound TCP traffic for that port on the DeskCamera PC. If the firewall rules are managed by hand, allow the ONVIF port in the same way.
If it does not work
If DeskCamera cannot start after changing the ONVIF port:
- Make sure the port is not already used by another application.
- Choose another port, or click Auto.
If DeskCamera says that the port is already used, see Fix ONVIF Port 8090 Already in Use.
