Hi,
I will investigate that. However, Windows is very strict what is allowed or not due to security. It also differs from running NCS as a service or in console mode. If you run the Windows client this can be enabled in the Settings.
Using rules and push nots is one way to handle this. Another way is described in the section for guides&tutorials How to control a remote computer from Netcam Studio server - play a sound when motion is detected
Thete might be other ways also …
