I use Netcamstudio on a MS Server 2008 R2 (no commercial use) so I just created my own certificate.
Thanks' for the suggestion.
Unfortunately the service and the NCS X seems not to be be possible at the same time.
The service always stops when NCS X is already running.
So difficult to switch when I'm away.
I tried netcamstudio without SSL but using a reverse proxy which takes care about SSL.
But I couldn't get it to work event without SSL.
Before I bought netcamstudio I evaluated a software called go1984.
Very nice software but way to expensive for private use.
They allowed both http and https at the same time using different ports.
Maybe something for the "suggestion" list of netcamstudio
