Frequently Asked Question
Use this article if the camera does not start and DeskCamera says that a port is already in use.
What you see
When you click Start, DeskCamera shows "Cannot start camera. Check log file for more details". The next line names the port. For example, it says "…TCP port 8090 is being used by another application." or "No free ONVIF port was found between 8090 and 8110…". The same can happen with the RTSP port.
What it means
Another program, or DeskCamera under another Windows user, already uses this port.
What to do
What to do first
Close the program that uses the port, or restart the PC. Then click Start. DeskCamera does not choose another port by itself.
Change the port
If you cannot free the port:
Click OPTIONS > General.
Under PORTS, find the port that the message names: ONVIF port or RTSP port. Click Fixed next to it.
Type another port number in the box next to Fixed, outside 8090–8110, for example 8200.
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.
Change the port number in the NVR/VMS too.
In Multiple cameras mode, DeskCamera ignores a Fixed ONVIF port. If the message names the ONVIF port, close the program that uses it instead.
If it still does not work
- Install the latest DeskCamera version.
- Check whether another DeskCamera camera or another ONVIF service is already using port 8090.
- Update firewall rules if the ONVIF port was changed.
- If several Windows users use the same PC, check the DeskCamera multi-user setup.
