OK, thank you. I’ve set it to ‘Automatic (Delayed Start)’ - correct ? One last question. On the Netcam Studio app on the iPhone, whenever the server starts, it sends a notification and the app responds by putting up a number on top of the icon to count the notifications. What is the proper way to clear those ? I’ve done it on a few occasions, but never really worked out how. After I’ve been into the app and done something, it’s “Oh, they’ve gone !” 
Finally (finally !) what sort of subscription do I need to run six or up to say ten IP cameras on a home installation ?
Thanks for all your help. Greatly appreciated
