Sony VISCA over IP unable to connect to NDI sources with error Only one usage of each socket address

The following error may be received when attempted to connect to Sony VISCA over IP on a NDI source:
Only one usage of each socket address is normally permitted.
This is caused by a limitation of Sony VISCA where it can only be used by one application at a time on the computer.
NDI connects to this when a camera source is added, preventing vMix from doing so.
To solve this, install the latest vMix ( or higher) and go to Settings -> Options.
Tick the box Enable Sony VISCA over IP with NDI click OK then restart vMix.
You will now be able to connect via PTZ.
This option reserves Sony VISCA on startup, preventing NDI from accessing it so it can be used by vMix instead.
